Well last week I was playin wow windowed and my PC hard locked. Now, I reset and that was it, put it down to my dodgy geil. Anyway same happened today. I left it and sound get coming back, going then catching up. Also I used alt tab, a while after the selection bar popped up (in single frames e.g. came on and it was as if it had froze). Anyway - I left this goin for a few minutes and it generally followed this pattern. I rebooted and the crash ocurred at 8:05 and at 8:07 in the event log I got this:
The driver nv4_disp for the display device \Device\Video0 got stuck in an infinite loop. This usually indicates a problem with the device itself or with the device driver programming the hardware incorrectly. Please check with your hardware device vendor for any driver updates.

So I guess this is what happened last time - any ideas? Both times was with different drivers (96.XX and 97.92).
