More Problems...

I haven't really found a way to figure this out either.

What could be happening though is Folding@Home could be writing to the disk when it does that. I'm not sure what causes that type of skipping though, I've had Folding@Home running on this computer since I built it. Games ran fine at the time. (Just to be clear, the video is of me playing a game. I can watch videos and such just fine).

I'm with you on it not being a video card issue though. If it was, I would probably be seeing more glitching outside of games, which I'm not.

Did you have a chance to watch the video I sent you?

Grrrr....still having problems.

Still not closer to figuring out what is causing this.

I did use my multimeter on the 6 pin connector for the graphics card and came up with 12.40.

I couldn't run it on load though since the probes were too big.

I have seen dying/almost dead cards display the desktop and videos fine but as soon as any real load is placed on them, they crash or pixelate in games. Typically nvidia cards also show weird glitches on the desktop and ATI cards tend to only be affected under load which may be that way on purpose.
Try a much older game like Command and Conquer Red Alert or something from the DirectX7 era.. if it plays that fine but the newer games still crash then I really do suspect a dying/dead card.

I don't think you have a PSU problem. If it was a PSU problem it could be caused by a glitch in the PSU output which is something you won't see or detect with a multimeter.

How are your CPU priorities set? Something is making the thing "burp".
