Hi Guys. Can anybody help & explain, why Doom 3 is crashing after about 10 minutes. As far as i know all drivers are up to date. PC system is, Fujitsu Siemens. Pentium 4, 3.20 GHz. 1.00GB of Ram. Radeon X 600 series games card. 4 months old. Played the game on my last PC, with no problems. I also have Half Life 2 installed, where there is no problem.
