I have a problem with my computer freezing up. It seems to be only when im playing ghost recon, but im not 100% sure on that. I can't control alt delete I have to hit the reset button in order to be able to boot back up. i had the computer built, so i first thought it was my video card so i went out and bought another one and that didnt work. i have updated sound card drivers and video card drivers. i am using xp pro with a Intel pent 4, 2.4 hyper threading processor with radeon 9000 video card which has been replaced now with a geforce 5200 video card. There is three fans in my tower plus the video card has a fan on it. i also opened up the tower and put the fan blowing in the tower, thinking it might be a heat issue.
