yesterday i had an electrical problem in my computer (hard drive fire) and the usual stuff happened, ie cpu clock speed set to 1.6 ghz and whatnot. but my graphics card also took a hit. under vista, it works perfectly, but under xp 64 bit it will only use one card, not matter what i set it to. i know this is the problem because i get virtually identical 3dmark 06 scores in xp as i do in vista with only one card enabled, and the same scores in xp with one card as with 2. i tried reinstalling the drivers and messing with the control panel, but none of that worked. MSI is a terrible company (already sent in the card a few times for overheating, with no replacement), so i cant send it back to anyone. ideas?
