Anyone Clued up on Gfx??

[Thumper]

i have recently just had 100+ trojans removed from my comp and i also had it sped up at the time by removing all the **** i didnt need etc ...
since then when playin mir 3 i have been getting gfx errors in the sense of the screenie below

i have swapped the file to a diff comp and seems ok so far
i have also uninstalled the gfx drivers and reinstalled the new up to date ones but it still does this
any ideas??
if u need more info i will tell ya what i know and or done if u need it

if you had that many viruses i would just reinstall the pc. Who knows what damage they have done to windows system files. Looking at that and what you done so far i would suggest that would be the best and safe solution also they could still be in your _restore/ folder which isn't good either
