I have an AMD Athlon1.4 on a QDI Kinetiz 7E-A with 640MB RAM and a Soundblaster Live 5.1. I use Windows XP Profesional. I recently bought a Creative Geforce4 ti4200 graphics card. I play games like Spiderman The Movie, RTCW, Warcraft III, Jedi Knight II, Colin McRae 2.0 with full detail (1024x768 32bit) and they run very smooth and with no problems. When I try to run F1 2002 or Grand Prix 4 almost immediately my computer locks and I have to reboot. The games run tests on my system before they start and find no problem and suggest full detail. I have tried all resolutions but still after I get out of the pit lane the game locks. I use the Nvidia 29.42 drivers but I have also tried 28.32 with no luck. Motherboard monitor shows that my CPU temp is 42C and Inside temp 32C. This also happens when I run Rally Trophy. Can this be happening because my card is overheating? If this is my problem, how do I solve it? I think Spiderman is a very demanding game and I have no problem running it with full details for as long as I like. I have heard others with same issues. Please help
