Problem description After playing Battlefield 2142, Quake 3, and Vanguard: SoH in about 5-30 minutes, my computer freezes up with repeating sound. Sometimes when that happens, I get a BSoD stating nv4_disp.dll is the problem. The problem has not occurred in Warcraft 3 (yet), but recently it happened during video playback. After rebooting, the same video file could be played without problems. I've also had a few IRQ, and PAGEFAULT BSoDs. After I disabled the on-board integrated sound card in BIOS, I've not gotten any more IRQ BSoDs, but I'm not positive it actually is fixed. However, I am positive I'm still getting the PAGEFAULT BSoD, and my games freezes up all the time. I've reinstalled all my drivers and the operating system (WinXP) several times without any luck fixing the issue. I've also tried earlier versions of my graphics drivers (Forceware) without results. I believe it's a hardware or driver problem. Though, I'm not positive I have only one (1) problem. I've logged the system temperatures right before the freeze ups, and they are normal. The temperature log file is attached. No hardware has been overclocked. I've tried underclocking my graphics card, though, but it didn't help. I have also updated my BIOS three times. I have provided a minidump from a PAGEFAULT BSoD and a pstat.txt, and will continue to provide minidumps if I get the opportunity.
