My PC has a horrible habit of crashing when it's doing 3d stuff - Deus Ex, Everquest, Morrowind to name but a few - sometimes it will hang, sometimes I get a BSD, and sometimes it goes back to the desktop. I've got a Athlon XP 1800+, with a SB Audigy, GeForce3 Ti 500, 1 gig of RAM, a 100 gig WD hard drive, and a VIA motherboard. I'm using the latest drivers for anything I can think of - Processor, GeForce, SB, but nothing seems to make any difference. There doesn't appear to be any cast-iron crash method: sometimes I can use the PC for hours before it happens, sometimes only a couple of minutes. It's rather frustrating, to say the least!! Any ideas? Thanks in advance.
