Computer won't POST after dissembling it...

it could be the gpu as I mentioned it before, or it could be the PSU as slay suggested before, or it could be the motherboard as MoM suggested before. We're giving you plenty of ideas as well as ideas of how to test for it, so instead of saying well it could be this or it isn't this try some stuff out and get back to us on what works and what doesn't. Retelling us what you've already said doesn't help you or us fix the problem.

I don't have plenty ideas on how to test for it. It's pretty much down to the CPU, GPU, or Mobo. From here, there's nowhere to go. I'm not going to put these parts in my new computer and risk screwing that one up too.

take the gpu out of your new computer and put it in the old one, do the same with the PSU, there's a chance it's that, I know you've ruled it out but until you test it and make sure it's still suspect. If neither of those are the culprit then it's probably the motherboard.
