Robert Long7 said:I tried swapping in a different power supply, but the PC still won't budge. I pulled this spare from an old rig that's been sitting idle for three or four years. Here's what I'm working with:

I really wouldn't advise messing around with opening up a power supply unit, because if it still won't boot with a different one, then I suspect the issue probably isn't actually the power supply itself.
Maybe you could start by checking the CMOS battery? After that, I’d suggest taking the whole rig apart and giving everything a really thorough cleaning—you know, grabbing a nice soft brush, maybe one of those fine makeup brushes, and using it to carefully clear out the RAM and graphics card slots. Once you've got everything back together, give it another shot. You might also want to try moving the memory to a different slot, or perhaps just testing it with a single stick at a time to see if that does the trick.
I’ve definitely run into similar headaches myself, once due to a dead battery and another time because of some weirdness with the RAM. It sounds a bit bizarre, I know, but sometimes a computer just refuses to behave unless the memory sticks are seated in a very specific order in their exact slots. I mean, it’s totally strange, but I've had situations where two identical sticks would completely crash the system, yet if I just swapped their positions, everything would suddenly work perfectly fine.
