Just as the title says, my computer FREEZE up after 10-40 minuts of gameplay, now, some games however seem to work better than others. For examlpe Splinter cell chaos theory and king kong worked allright. Bmfe 1, Bfme 2, counter strike, need for speed most wanted and f.e.a.r freeze up. Things i have tried: Check temperatures. Try different drivers. (Gfx and audio) Reinstall windows. Check for dust. Knock three times on chassi and say "Aaabracadabra". Checked RAM. Removed one RAM-stick. Even bought myself a brand new Power suply today. Q-tec 500W. My last Power suply was a 300W so i though "More power should fix this". But ..... no. Help me! My specs: Intel pentium P4 socket 478 Asus P4S800D-X 1GB RAM Nvidia Geoforce 6600 GT Q-tec 500W Big Fan. Windows Xp Thank you!!
