Upgrading my mother in law’s Compaq Presario S5140WM

Dave Farquhar Hardware , , , , ,

About the time my wife and I started dating, my mother-in-law bought a new computer. With an Athlon XP 2600+, that Compaq ought to be faster than anything I own. Even though it’s almost three years old now, it ought to still be pretty good.

It wasn’t. I fixed that.It has the Compaq name on the front but anymore that doesn’t mean much of anything. It’s a clone made in the Far East, with bog standard parts inside. When I visited earlier this month, she complained about its speed. I couldn’t find anything obviously wrong, but I checked the memory usage. It was over 250K with nothing loaded. Not good.

I happen to know the F-Secure-based security suite her ISP issued her can use nearly 256 megs all by itself sometimes. Not good.

So I paid Newegg.com a visit and ordered her 512 megs of memory. For 35 bucks, shipping included, why not? It’s overkill, but memory requirements are going to go up before they go down, and there was little point in buying half as much memory for 10 bucks less.

I bought Viking. I prefer Crucial or Kingston, but in my days doing desktop support, the people who insisted on Viking did OK, and it was cheaper the week I ordered it, so I got it. Don’t buy the cheap and nasty no-name stuff; the failure rate on no-name commodity memory has always been very high–somewhere near 30 percent, in my experience, and computers are more sensitive to memory today than they were in 1995 when I got my first job doing desktop support.

When I got the computer open, I saw it has an AGP slot. I really should get an AGP video card to put in the computer. Built-in video steals some system memory, which isn’t a big deal when you have 768 megs, but it also steals memory bandwidth. It’s like that bridge I cross over every day to go to work–it’s normally three lanes, but they have it closed down to two or even one lane some days. So it takes a longer time to get over that bridge. If I put a video card–even my old Nvidia-based card I bought back in 1997, if I could find it–with its own memory in her computer and disabled the onboard video, it would be like reopening that lane, and her CPU would have a full three lanes to work with when accessing memory.

I just checked Ebay, and found an Nvidia TNT2-based card for 99 cents Buy-it-now, with $9 shipping. The shipping is a ripoff, but the seller is probably paying a couple of dollars for the card and making $4 on shipping. At $10, the card is more than anyone needs for word processing and Internet use, and it’s probably better than the built-in video would be for light gaming. It’s a cheap way to soup up a computer like this.

If you can’t afford to buy any memory for this or any other computer with built-in video, but you’re running short on memory, here’s a free upgrade: Go into the BIOS, and set the amount of memory dedicated to the video card as low as you can. In this case, I can go to 8 megs. You won’t be able to run high colors at high resolution after doing this, but if you’re happy with 1024×768, it’ll give your system some memory back and make it a little more peppy.

I sure wish Intel or AMD would steal the old Amiga concept of chip memory, which was a bank of memory that could be used by either the video chip or the main CPU, at the expense of speed of course. But slow memory is still way faster than the swap file. The system just gave priority to the main memory (called fast memory) when it was available. It’s amazing how many good ideas were out there 20 years ago, some of which we’re enjoying today but some of which are sadly lost to history.

And, as always, a newer, faster hard drive is a good way to hot-rod an aging PC if it feels a bit sluggish.

But, $35 worth of RAM and a $10 video card goes a long, long way.

The tipping point of obsolesence

Dave Farquhar Hardware , ,

Gatermann just sent me a link to a $33 Dell P3-500 at Surplus Computers. It got both of us feeling old, because the day when that was a hot machine doesn’t seem long ago at all to either of us.

My initial reaction: That’s a lot of computer for 33 bucks. You get a 500 MHz CPU, 128 megs of RAM, and a 6 gig hard drive.

And then I got to thinking about it some more. I can think of people who could get by with that machine, but there’s a good reason why the P3-500’s star has fallen and you can get one for $33 without feeling like you’re at a Who concert.I guess first and foremost, you don’t get an operating system. That’s fine; OEM copies of XP home are cheap enough. Older versions of Windows are even cheaper because nobody wants them.

But even if you’re running 2000, you really want a minimum of 256 megs of RAM. For XP you want more than that; my mother-in-law’s PC, which is a Compaq with some flavor of Athlon in it, really drags these days because it only has 256 megs.

So I bopped on over to Crucial to see what I’d need to make that old Dell Optiplex GX1 rev its engine. And the price of a 256-meg DIMM was (sit down): $77.

So to max out the memory on this $33 machine, you’d need to spend another $231.

Gatermann just bought a gig of PC3200 DDR memory for $98.

So rather than spend $231 on 768 megs of PC133 SDRAM, you’d literally be better off buying the PC3200 and getting a $50 motherboard and a $60 CPU to put on it.

Trouble is, this is a Dell. You can’t swap off-the-shelf motherboards into a Dell. Some Dell cases will take a standard board, but you’ll have to replace the power supply. But the GX1 doesn’t use an ATX board.

That’s why this system costs 33 bucks. It’s pretty much at a dead end, and the memory it uses is no longer a mass-market item, so its price is inflated. It’s the same thing that happened to the 72-pin EDO SIMMs we used to put in our original Pentiums–you know, the ones that topped out at 233 MHz.

It’s a great machine for a tinkerer who happens to have a lot of PC100 or PC133 memory around, or for the Ebay addict. Obsolescent memory always sells more cheaply on Ebay.

I’ve always been in favor of upgrading a computer until it no longer makes economic sense to do so. If you’ve ever wondered when that is, this is a classic example.

Running Knoppix on a Proliant with a SmartArray controller

Dave Farquhar Servers and Networking ,

If you’ve ever tried to run Knoppix on a Compaq or HP Proliant with a Smart Array controller, you probably got a rude surprise.

Here’s how to make the hard drive(s) show up.Open a shell window.

Type ‘su’ (no quotes) to become root.

Type ‘insmod cciss’ — you may get a message that it’s already installed.

Type ‘cd /dev’

Type ‘MAKEDEV cciss’ (this is case-sensitive).

Now Knoppix will see your drives so you can mount them and/or edit the partitions with qtparted.

Troubleshooting a Compaq Proliant 1600

Dave Farquhar Servers and Networking , ,

I still work on a lot of Compaq Proliant 1600s. In their day, they were a very versatile server, packing lots of drive bays and open expansion slots into a 5U package. They were also very reliable.

Now that they are five years old or even older, they are less so. But I’ve collected some good suggestions from Compaq and HP technicians about working on them.The biggest problem with the 1600 is that so many parts are socketed. Over time, socketed components tend to work themselves loose. So, when a 1600 crashes a lot but will pass its built-in diagnostics with flying colors, the best thing to do is to completely disassemble it and put it back together.

If it seems to be having memory problems, don’t just reseat the processor board and/or replace the memory. I had one 1600 exhibit memory failures that would not go away until I replaced the PCI board, of all things. Why? Beats me. The HP technician was as stumped as I was. So reseat that board too.

It never hurts to clean the connectors when you have the system apart. Get some zero-residue contact cleaner from a hardware or auto parts store. Be sure it’s zero-residue. A lot of contact cleaners contain oil, which isn’t going to help intermittent electrical connections at all. If in doubt, skip the contact cleaner entirely and clean the contacts with a cotton swab and rubbing alcohol instead. Need I also mention you need to stay grounded at all times while doing these procedures?

When replacing the PCI and CPU modules, you have to use a lot of force. Don’t rely on the plastic releases on the back to put them in. Whenever I’ve seen a veteran Compaq technician reinstall one of these modules, he’s slammed the module into the back computer with so much force that it moved the system. If you don’t think you’re going to break it, you probably aren’t doing it hard enough.

Newer Proliant servers have many fewer socketed components, so their long-term reliability prospects are higher. They also usually have LEDs that indicate failed components, making diagnostics virtually irrelevant and system repair much more straightforward. But when replacement isn’t an option just yet, it’s nice to know there are things to do to return a 1600 to life.

Hard drive upgrade tips for older PCs

A hard drive upgrade is one of the best ways to extend the usable lifespan of a computer.

A lot of people come to this site looking for hard drive upgrade advice, but I realized that it’s been a long time since I’ve written anything about that. Since there are some gotchas, I need to address them.

Is this Apple a surprise to anyone?

Dave Farquhar Macintosh , , , , , , , ,

So, Apple unveiled its new Imac today. (I’m sick of improper capitalization. We speak English, not C++.) To no one’s surprise, I’m sure, it has a bigger screen. And I’m sure it’s not too surprising that they crammed everything into the unit next to the screen. It’s the next logical step, after the lamp-shaped Imac.

So how’s it gonna do?I think it has potential. Do people really want laptops because they can carry them everywhere they go, or do they want laptops because they can move them about the house freely and don’t have to have a dedicated “computer room”?

I suspect to most people, the latter is more important. Most people have better things to do with their lives than surf the ‘net at Starbucks or Panera Bread.

This new Imac can go on a small desk in a study or spare bedroom and not take over an entire wall the way computers have been doing since the late 1970s. As long as there’s a way to add some memory, and there are ports for people to plug in their digital cameras and their portable MP3 players and a printer, they’ll be happy.

Who knows, maybe demand for wireless printers will increase too.

Some analysts have said they don’t think all-in-one is the slam dunk it was in 1998. I agree it isn’t, but small is a slam dunk. Witness the explosive popularity of cube PCs. Yes, it flopped for Apple, but Apple’s cubes lacked the flexibility, there was too much confusion about their expandability and what exactly they were compatibile with–I designed a Mac network for a client right around the time the Cube was released, but the rumor was it would only work with Apple monitors. That alone killed the deal. They bought G4 towers instead, which would work with NEC and Viewsonic monitors.

But the other problem with the Cube was the price. Yes, it was cheaper than a G4 tower. But the price difference wasn’t enough to make people willing to take a chance on it. And besides, if it was cheapness you wanted, there were at least four companies willing to sell you a PC for half the price of a Cube. Emachines would even sell you a PC for half the price of an Imac.

And that’s the biggest problem I see with this new Imac: price. $1299 gets you in the game. Ten years ago, that was cheap. But this isn’t 1994. Emachines didn’t exist in 1994, and while a Mac would cost you more than a Packard Bell, there wasn’t much price difference between a Mac and a Compaq or an IBM. Compaq or IBM usually had one model that sold for a hundred or two less than the cheapest Apple, and Apple usually wouldn’t give you quite as much CPU speed or quite as much disk space, but if you walked into the store with $1500 in your pocket, which was pretty much the selling price of an average PC, you could walk out with a Mac just as easily as you could walk out with something that ran Windows.

What will Dell give you today for $800? 2.8 GHz, 256 MB RAM, 40 GB hard drive, CD burner, printer, 17-inch monitor, and some software.

For the same money, Apple gives you 1.25 GHz, 256 MB RAM, 40 GB HD, CD burner, and a 17-inch display. No printer.

For $1,299, the price of the new Imac, Dell gives you twice the CPU power and twice the memory. Just not as much wow factor.

Yes, I know the Pentium 4 is a horribly inefficient processor but the design does scale surprisingly well, and efficiency alone won’t make up a 1.6 GHz speed deficit. Besides, if you’re willing to spend four figures, you can get an AMD Opteron. Just not from Dell.

Will this Imac sell? Yes. Will it do much to increase Apple’s 2.2 percent market share? I doubt it. The main audience is going to be people with aging CRT-based Imacs who’ve been holding out for something with a G5 in it. They’ll buy it, find it’s a lot faster than their old one and takes up less space. Of course they’ll like it. But it’s still the Amiga problem. The Amiga didn’t take over the market because it it only sold 6 million units. The Amiga was a commercial failure because those 6 million units sold to 1.5 million people.

People will ooh and ah over how little space this new Imac takes and how convenient its wireless keyboards are. But most of them will buy a Dell because it’s faster. Or cheaper. Or both. Maybe they’ll complain about how much less convenient it is, but it’s just as likely they’ll forget about it.

It happened with the first Imac and it happened with the Cube and it happened with the dual G4 and it happened with the G5. Who are we kidding? To some extent, it’s been happening since 1983 when the Lisa came out. People see the machine and it knocks their socks off until they see the price tag. The classes buy it anyway, while the masses figure out how to get by with something cheaper.

History is going to repeat itself one other way too. Somewhere in the Far East, I guarantee you a no-name maker of whitebox PCs is designing a box that puts the brains of the outfit behind the LCD, just like this Imac. Maybe the thought didn’t occur to the designer until this week. Maybe the designer has been working on it for months already.

It will look a lot like this new Imac, only it will have an AMD or Intel processor in it, and it will run Windows. It might be three months before we see it. It might even be six. But it will appear, and it will be priced under $1,000.

It will sell. And within another six months, everyone will be doing it. This new form factor may not come to dominate the market, but it won’t take much for it to outsell this new Imac. A small percentage of 97.8 percent is likely to be a lot bigger than even a large percentage of 2.2 percent. Compared to the new Imac, these clones will look like a runaway success.

And Mac fanatics will be screaming about another Apple innovation stolen by someone else.

No surprises in the PC Magazine reliability/service survey

Dave Farquhar Hardware , , , ,

It’s that time of year again. Time for PC Magazine’s annual reliability and service survey. I’ve been reading it for almost half my life, and half a lifetime ago, it really meant something.

Today, the subtitle ought to be “What happens when you outsource.”So what does happen when you outsource? All the PCs are basically the same these days. It makes sense. We’re down to three or four suppliers for almost all of the chips on the motherboard, and everyone, including the big vendors, buy their motherboards from one of a half dozen or so companies now. Some contract manufacturer in the Far East puts them all together and puts some other company’s name on it.

The good news is that if there’s a secret to building good, reliable PCs, it’s really poorly kept. The basic hardware is much more reliable today than a decade ago. Back when I sold computers at retail, I remember a Compaq sales rep complaining bitterly that Intel’s “Intel Inside” campaign was hurting them by making everyone think all computers were the same inside. At the time they weren’t. Compaq’s engineering and rigorous testing didn’t always produce the fastest PCs, but they were always near the top, and it did produce some really reliable stuff.

Would that same philosophy applied to today’s technology yield something better? It’s impossible to know. Compaq PCs are exactly the same as everyone else’s these days. The good news is the hardware is about as problem-free as it was back then. And so is everyone else’s. The only difference is the software the manufacturer loads on them.

You may be surprised, but even the bargain-basement eMachines scored high on reliability ratings. It turns out it’s cheaper to get things right the first time than it is to cut corners on quality and have to accept lots of returns. Their machines were dirt cheap, the company was profitable, and the reliability was good. That’s why Gateway bought them and then turned management of the combined company over to the eMachines management.

Speaking of Gateway, support is almost uniformly lousy across the board. People have always complained to me that the support people don’t know what they’re doing. Now it’s hard to know how much the phone techs know because you can’t understand them.

Someone has got to realize this makes poor business sense and make a change. IBM knows, but IBM doesn’t sell PCs at retail anymore. In the early ’90s, Gateway had tremendous brand loyalty. Their PCs were terrible, but the tech support was friendly and determined. When Dell and others started undercutting Gateway’s prices, they cut costs by decimating their tech support. The result was lousy computers and no help getting the problem fixed. The only thing left to do was to buy eMachines, whose management had walked into a similarly bad situation in 2001 and righted it.

It’s pretty obvious to me that the way to break this logjam of sameness is to offer first-rate technical support. I want to believe that the first company that moves its technical support back to the United States and advertises the fact would even be able to get by with charging a premium price.

In the meantime, you stand to get slightly better support by buying from a retail store rather than over the phone or web, if only because the store will be able to help you with basic questions. The quality of in-store help varies widely, but if you find good help in the store, find out that person’s name and ask for that person if you have to call again. Most people who are really good don’t stay in retail for long–at least one company here in St. Louis scouts the retail stores’ computer help and tries to hire away anyone over the age of 21 or 22 who seems to be any good–but you may get some good help in the meantime. Use the manufacturer’s support as a backup, if the store will let you.

Advice for setting up a computer lab

Dave Farquhar Hardware , , , , , ,

Two weekends ago, I headed back up to Bethlehem Lutheran Church to rebuild the computer lab I had set up for them a few years ago. Built on P3-based Compaq Deskpros and Windows 98, it had held up, but was desperately in need of repair.

The vision of this project was to set up a lab in a declining neighborhood, where kids could come to do their homework and adults could come to learn computer skills. The lab is run under adult supervision, and outsiders with teaching and/or training experience come in occasionally to teach computer literacy classes.

Ultimately, I want this project to produce some sysadmins in North St. Louis. Years ago, when this was in the planning stage, I told Pastor John Schmidtke that I wanted to see some Mercedeses and BMWs in that neighborhood, purchased with salaries earned from skills picked up in that lab.

Well, that hasn’t happened yet. But there’s still time. In the meantime, how about if I talk about what I’ve learned from three years of operation?Fancy computers not necessary

These were midrange machines when they were new. The lab cost some $10,000 to build, including materials to renovate the room. A contractor who attends my church renovated the room to my specifications. For what it’s worth, I told him there would be about 10 computers there, and the keyboards needed to sit so that a five-foot person’s elbows would make a right angle while seated. He built an around-the-room desk to hold the computers and bored out a couple of holes at each station for the keyboards.

Back to the computers. Today those computers would be worth about $100 apiece. That’s OK–they’re fine for word processing and e-mail, casual web browsing, and educational games, which was the goal. They were fine then and they’re fine now.

Any business with a philanthropic mindset could duplicate what we did here with a dozen outmoded office computers. A Pentium II with 64 MB of RAM can run Windows 95 or 98 adequately. There’s no point in messing with anything lower than that, since P2s sell for 50 bucks a pop these days. One thing I will say: The quality of the keyboards, mice, and monitors is much more important than the computers themselves. If people are going to be typing, they need decent monitors, a good mouse, and a keyboard that doesn’t feel like oatmeal. So if you’re working with a budget, plan on spending the most on monitors and optical mice.

Adequate power outlets completely necessary

There was only one hardware failure in this lab’s three years. One computer wouldn’t run, no matter what I did. It wouldn’t even power up.

Well, speaking as someone with a decade of professional experience in sales and service of computers, I’m embarrassed to say the computer that failed wasn’t plugged in. It looked like it was plugged in. But with the electrical outlets in a mismash and the cables all over the place, it wasn’t. Why didn’t I try another power cable and discover the problem? I have no excuse.

I suspect someone needed an outlet for something–be it speakers or a hair dryer, you never know–unplugged something at random, then didn’t plug it back in when finished. Worse yet, the business end of the cable ended up in a box under the desk, so everything looked fine. The result was a computer that didn’t run for about two years. I didn’t even find the stray end of the cable until I traced several other cables.

So provide as many outlets as your breaker box can handle. Provide extras. People will bring in other things they want to plug in. Three outlets per seat (computer, monitor, and speakers) is inadequate. To be safe, plan on four.

Create system images

You’ll have to reload the system no matter what you do. Lockdown software can be counted on to break things for the innocent and at best only slow down the people who are going to circumvent it. When the goal is for people to learn how things work, they need to be at least somewhat free to experiment. So make images of a working system with all software installed. Train someone to re-image the system. Then don’t be shy about re-imaging. Do it once a week or any time something goes wrong with a computer. If you can’t afford Norton Ghost or PowerQuest DriveImage, a freeware alternative called Savepart exists. Use it. Come to think of it, use that, and spend the money you’d spend on Ghost or DriveImage on better keyboards or mice.

Use identical hardware

System images don’t save you much trouble if your hardware is all different. Your image probably won’t work. Use systems that are as similar as possible: same motherboard, same video card, same sound card (if not on the motherboard), same network card. Put the cards in the same slots on each machine.

Frequently you can get away with not being that careful, but trust me, you don’t want the one time in a thousand that it matters to come and bite you.

Match your hardware and operating system

Sometimes it’s not possible to use completely identical hardware. In those instances, make sure any dissimilar hardware is recognized by the OS without loading any drivers. For example, this lab has a mix of Netgear and Intel network cards. The Netgear isn’t recognized by Windows but the Intel is. So I made the image for a Netgear, and when the system comes up with an Intel, it handles the situation gracefully.

Do the same thing for the sound cards and video cards.

Don’t ask too much of your systems

Yes, Windows XP will install and boot on a Pentium II with 64 MB of RAM. But there is absolutely no benefit to it. XP wants lots of memory and CPU power, and when it doesn’t get it, it’s a slow pig. Realistically, a P2 with 64 megs ought to be running Windows 98. Don’t even try 2000 or XP unless you have P3s faster than 500 MHz with 256 MB of RAM.

While there are subtle differences between versions, for the most part Windows is Windows. If someone can use Windows 98 and Office 97, it’s easy to adjust to the current versions. Don’t be afraid of running back-level versions.

Get discounted charity/educational software

You don’t have to pay $200 for Windows and $500 for Office to build a computer lab for a charity. I don’t know what charity or educational prices are right now, but it’s a fraction of that. The rule of thumb is this: If you don’t pay sales tax, you don’t have to pay full price for software either.

Most computer stores can get you information on charity pricing. Support your local computer store. You might need it someday. Who knows–the owner may be able to get you a line on some things you need.

And if worse comes to worse, run Linux. That was my original plan, but Pastor Schmidtke wanted to use what local businesses were using. That’s a better plan, but if you can’t afford software, Linux works nicely and is more than adequate for things like word processing and web browsing.

Just do it. That’s about all else I can say. The lab in your head isn’t doing anyone a bit of good. If it’s worth doing, it’s worth doing badly. If you’ve got a vision for this, get what you can to get the lab up and running. You can always come back and add newer or more computers later.

Upgrade diary: Compaq Presario 7360

Dave Farquhar Hardware , ,

Last week, I talked about my plans to upgrade a Presario 7360. I can now present you with the executive summary.
This isn’t a project for the faint of heart or the inexperienced. Upgrading is certainly possible, but this is one of the most difficult upgrade projects I’ve ever done, and this is coming from a guy who’s done a lot of upgrades. I can honestly say that for every soda I’ve drunk over the past seven years, I’ve probably serviced one computer.

With today being New Year’s Day and me having the day off (mostly), I decided to tackle the project. If you’re stuck with doing major upgrades to a 7360, make sure you’ve got a long block of time where you won’t be interrupted.

Caveat 1: The first question is how to get the old motherboard out in order to do anything. You’ll have to, unless your hands are about half the size of mine (and my hands are smaller than average). Remove the two screws from the underside of the motherboard, then find a couple of convenient spots to grab onto, and pull the assembly toward the front of the case. The board will then fold out, like a door.

Caveat 2: The factory power supply is woefully underpowered. It might very well fail if all you add to the system is a CD-RW drive. And there’s no way it’ll work with a modern Athlon or P4 motherboard. Fortunately, 200-watt SFX power supplies, while not necessarily something every streetcorner computer store carries, are much more common today than they were even two years ago. Newegg.com carries a suitable replacement for around $25. Look for an Allied AL-B200SFX. Not only is it 200 watts, it’s also certified for P4 and Athlon use.

Caveat 3: If you haven’t yet gotten the idea that this case is crowded, the position of the drive bays makes it difficult for a modern Socket 478/Socket A CPU fan to fit without moving the hard drive. After replacing the motherboard, I had to bust out the hard drive, open up the slot intended for a Zip drive, and slide the drive in from the front in order for it to fit, then bolt the drive into place and replace that slot’s front cover.

Caveat 4: The front panel. Like many brand-name PCs, this Presario puts the front power button and all the LED leads in one easy-to-plug-in block. Unfortunately, there’s no industry standard pinout for that front panel. I happen to have two Compaq Socket A motherboards purchased from various closeout joints. Those two boards, and the Socket 7 board that originally came in this Presario, all have different pinouts. You’ll have to rewire that block, and it’ll involve some trial and error. Assume this part of the job will take an hour or two.

Caveat 5: Airflow. Add a second optical drive or hard drive or both to this thing, and there’s not going to be much room for airflow. Don’t upgrade with a high-end CPU.

Caveat 6: Clearance. The first HSF combo I tried was 2 inches tall. It didn’t fit, and there was no way to make it fit, unless I permanently removed the drive cage that holds the floppy and hard drives. I replaced it with a Speeze 5C12B3, which fit. The first memory stick I tried was 1.375 inches tall. It didn’t fit either–I had to locate a shorter one.

Overall recommendation: If you can upgrade this thing, you have my respect. I got one working, but mainly because I had a larger-than-usual selection of parts on hand. If this had been my first attempt at doing a motherboard swap, I would have sworn off the practice forever.

Chances are, if you’re reading this, you’re much better off buying an inexpensive replacement computer and relegating your 7360 to Web browing/e-mail duty, or donating it to a charitable organization that gives computers to the needy if your community has one (St. Louis does–Web Innovations and Technology Services, at 4660 West Florissant Avenue). Unless you tear into computers for a living, I wouldn’t recommend attempting a motherboard swap in this computer.

Beware the “flat screen” scam

Dave Farquhar Hardware , , , , ,

I was just pricing out some parts for the pending Compaq Presario upgrade when I remembered the latest scam–well, it’s not technically a scam, but it’s definitely deceptive advertising. Many stores offer a bundle with a low-end PC and a 17-inch “flat screen” for an unbelievable deal, like $499. Chances are, if you read this site, some relative of yours is going to be asking about that, if they haven’t started asking already. And I’m pretty sure you know that right now $399 is a pretty good deal for a 17-inch LCD flat panel alone.
Needless to say, that 17-inch “flat screen” isn’t an LCD. It’s a CRT. Sometimes they even use camera tricks in the picture to try to make the CRT look like an LCD.

In all truthfulness, that 17-inch monitor being advertised as a bargain flat screen probably does have a flatter screen than whatever your relative is using right now. And CRTs continue to improve steadily. But it’s still a CRT, and it’s probably not what your relative is looking for.

Tell your relatives to read the fine print and look for an LCD. And tell them to keep in mind nobody’s giving away LCDs right now, because LCDs are one of the very few things in the computer field that have held steady demand for the past couple of years. At least one consumer electronics chain used a 14-inch Mag Innovision LCD as a Black Friday special, pricing it at $99 after rebates the day after Thanksgiving. I expect that deal will reappear once or twice in the coming year, but a 14-inch LCD gives the same screen real estate as a 15-inch CRT. It’d be great for a second computer–I’ll eventually buy one to keep in my study, where a small and quiet computer is ideal–but it’s probably not what LCD bargain hunters are looking for either.

Oh, and speaking of the Presario, if you’re looking for a replacement power supply for it on the cheap either for a motherboard upgrade or because one has failed, the product you want is the Foxconn Allied ATX200SFX, priced at $19 at Newegg.com. It’ll also fit an eMachine and the small-form Gateway and HP PCs. The trick to recognizing an SFX power supply is to look at how it’s bolted into the chasis. If it’s held in by three screws, with two on one side and a third on the other side towards the middle, it’s probably an SFX form factor. A lot of smaller ATX power supplies use four screws. So ask your vendor lots of questions, and buy as much wattage as you can get in whatever size you’re stuck with.
