So far I have updated all drivers + directX, Im now using the catalyst 5.5 driver wich should be the best one.
My bios settings are fast write OFF and 4x agp.
Im on a 3200 AMD
1gig ram
Radeon 9800pro 256
And I have absolutely no skill with PCs, so please contribute if you have a possible solution

(I never had a problem running GW before changing the HD)
