What exactly does it do when it crashes? ie: parti-coloured screen? error messages? Computer simply freezes and goes to a blank screen? Computer shuts off? If you can give more detailed info, maybe one of the boards techno-kids can help.
I've got a radion 1900XTX graphics card, and I STILL have weird things happening in the game graphics-wise. Doors are slow to open, fountains don't flow correctly, spell effects are in slow motion, and those handy-dany corpse-mashers are slower than slugs. Haven't figured out why yet.
