What's wrong with my video card?

[Kccdx2]

In the past month, I replaced my only Epox 939 mobo with an asrock 939 (AGP & PCI-e compatible model) and my onld A64 3200+ with a X2 3800. After this, I wiped all my drivers clean and reinstalled them one by one. However, now the videocard has gone to the crapper. WoW is now completely unplayable <1fps, old old 98' games run at 20 fps...what's up? Did I forget something in the upgrade? Send help!
