I got a new video card since I was blaming this on the fact that the fan stopped spinning on my 7300 gt. I upgraded to a radeon 4850 and the problem still persists. for a while it stopped having errors when I had it hooked up in my living room, but now it's back in my room and the problems are happening again.
This whole time I have had a very large box fan next to my open case and it worked at one point in time. Now the errors are happening even with the fan turned on high (it spins fast enough to propel an airplane into space).
I just upgraded to the latest video card drivers but that hasn't helped either. I use an Asus m29-e mobo, 2 gbs of ram, an sata 500 bg hd and an amd atholon fx-62 2.81 dual core cpu. I don't really know what to do.
