sorry if this has been posted twice there was some kind of error when I was submitting (as if I haven't got enough problems with PC's) I dont know exactly whats happening here, but for a while now, whenever I play on any videogames on my PC, after about 5 sometimes 10 minutes, the system completely freezes up and I have to manually reboot. I can be playing any game old or new, and eventually the on screen images freezes, then i hear pops and clicks then the screen goes blank. this started happening about the same time I bought F.E.A.R since then its happened to all of them GTA Warcraft. Hitman (the first one) I can only assume its videocard related, but could be wrong. i've run DXDIAG and everything checks out, updated the sound and video drivers, but to no avail. anyone have any ideas what could be the problem. it only happens during games, and at no particular point. I've attached a copy of my DXDIAG Report, any help or advice would be much appreciated. Thanks.
