Random system unstability

[Intelman07]

First of all my updated specs.

DFI Lanparty nForce 4 Ultra-D
AMD 64 3200+ @ 2.5Ghz
Corsair XMS Twinx 2x512MB
Seagate 7200.9 250GB HD
Nvidia 6800

Ok, my computer was working fine and dandy, but now it has some strange issues. Lately Battlefield 2 has been crashing, and causing my computer to blue screen. The map will load, then as soon as I can select a spawn point for the first time, the game freezes then a few seconds later it bluescreens and insant reboots. The bluescreen only flashes so I can not read it. I have ran Prime95 for 20 hours with a blend test with no error. I am running it again just to be sure, and am going on to memtest. I also tried changing drivers for my video card. I am actually thinking it might be my 7200.9 and my nForce 4 conflicting, since that is the only new addition to my computer, just got it this week. It has worked with the 7200.9 though, it would be odd for it just to go nuts now. Just wanted your guys' input, thanks!

This sounds like a PSU problem. That hard drive may have been the last straw for your psu. Hard drives, CPUs and GPUs are all drawing from the 12V line of the PSU. Prime95 and similar programs are great for testing CPUs, but they don't stress the video card. In a game everything is drawing peak power, including the GPU. Doesn't sound like heat if it happens so quickly either.

Try 3D Mark or another game or anything that will give the entire system a simultaneous workout and see if it crashes. You might also try unplugging a couple drives and seeing if the crashing still happens.
