Re: Fedora 13, Xorg 1.8, 9800GT - full-screen video playback causes kernel crash
Given your problem happens for VDPAU video, non-VDPAU video, and general terminal usage, I'd like to say this is a HW issue. However, you say that everything works OK in Windows. That said, the Windows and Linux drivers may exercise the GPU in different ways. Is your GPU over-heating; did the fan fail, and do you have sufficient air-flow to the card? Perhaps you can check nvidia-settings and see if that reports higher-than-normal temperatures around the time when the crashes happen.
