I dragged my computer back over to Micro Center this afternoon. It took three of us, but we got the computer working.
It’s a long story. It would have been a much shorter story if I’d remembered my rule #1. I won’t bore you with the details, except to say the second technician, upon hearing the only thing we hadn’t swapped out was the power supply, dragged a power supply out of the back. We plugged that power supply in, and heard the sweet gimme-some-memory scream from the motherboard failing to POST. Incredible. So we powered down, reinstalled the memory, and watched the system POST.
