i just bought a new stick of 256 ram, dvd rom, and a new video card geforce 4 ti 4200 128mb. i have a fresh install of windows xp, got all my video drivers and everything worked fine for a few days. the problem is that when i play any game black hawk down, c&c generals, counter strike, bf 1942, anything after about 5-30 min it crashes like every time. not once have i been able to run a game for longer than an hour. i thought it was heat so i took the side of my case off put a window fan on high and made sure no cables inside were killin air flow. but still crashes. so now i have no clue what it could be? can anyone please help me????? thanks in advance ....oh and i have direct x 9 and when i crash it either shoots me right to desktop or gives me windows error (you know the one where you can send a error report)
