OK. I was on the phone with eVGA, I followed what he told me to do. I put a separate 12V line to my video card. I turned it on, and I saw a huge flame and flash from the window of my case, WHILE ON THE PHONE. I inspected the case. All compoents were ok, except the video card. It was scorched. It happened the moment I turned the power on. I put the old ATI card in, and the computer did indeed still function.
Despite the fact the burn was not covered by the warranty, he confirmed with his supervisor it was OK to RMA the video card. lol
I put my old ATI cards back in the case, but I was still having the same problem. Driver conflicts are not the issue. Its system performance.
I'm starting to think that the low voltage of the old PSU damaged my computer somehow. I dont believe it's the CPU. However, windows loading time takes forevvvver. I'm starting to think its either my memory, or my hard drive. However, given how my hard drive has nothing to do with my video game performance, since it skips at fixed intervels, like every second and a half, ONLY when I'm running a program at the same time as a game, I believe its memory.
Can a knowledgeable person answer this post, and verify what kinds of computer components that are most suspetible to damage from low voltage?
