Well, I just bought another computer off of ebay, cause it sayed it wasn't powering up, I got it yesterday, and it powers up fine, only thing is the motherboard is fried, and maybe the core 2 duo that came with it too. I did a lot of testing on that board, and no beeps when the memory wasn't in it, and it wouldn't even power up when the cpu was out of it, which my other computer did.
I replaced the motherboard on the first computer I got on ebay, and it works great now. This thread can now be closed.
