Mark.... I was having the same problem. Doom3 would lockup or crash after
about 10 to 15 minutes using an AIW 9700. I just upgraded to the current
drivers on the ATI site and it seems to have corrected the problem for me.
Runing AGP ap at 512 mb (1 Gig system ram) at 640 x 480 32bit my AMD 2800+
system seems stable now. By default, on my sustem, all the graphic setting
are quite low in Doom3.

Is anyone else out here having lockups/VPU recovery errors, about 10- 15
mins into the game? I've tried updating drivers for the 9700pro (cat 4.9)
via chipset drivers, soundblaster drivers, even turned off fast writes and
changed the AGP ap size to 32mb. The support website for doom suggested
changing the desktop res to 800 x 600 32 bit colour i've done this and
turned off antivirus etc and all its done is make the game run a little
longer without crashing. Help is there anything else i can do. I've even
thought of upgrading to to an nvidia card (don't want to rather wait until
i
get a new mb with pci x and get one of the new radeons).
Please help
It could be that my 550 watt psu failed and i'm using a 300 watt one? or
over heating?
