4) If it comes back as an ATI whatever instead of a generic video card, go to #2 and repeat until it doesn't. You may have to do this once for each version of Catalyst you've installed since you installed Windows.
5) Run Driver Sweeper (at guru3d, free)
6) Reboot
7) Run Driver Sweeper again, twice, to confirm everything is gone
8) Reboot
9) Ok, now you should be using Generic still and have no driver crap left over. Delete the ATI folder out of Program Files.
10) Install an OLD version of Catalyst prior to 8.11. Preferably you go further back to like 8.6 or 8.8. 8.11 and all versions of 8.12 are seriously buggy on at least 3k and 4k series cards and I had the same issues as you until I wiped out everything and installed older drivers. Fortunately, 8.12 is only about 1-3% faster than 8.6, so you aren't missing out on much.

Anyway, if you don't BSOD and get driver responding errors anymore, you'll know it was the dreadful 8.11/8.12 fiasco to blame. Install your other cards again.
Thanks for the info, but already re-installed XP x64. I was completely done with Vista Ill wait for SP2 or so before Ill try it again.

Anyway, what's considered to be a safe Voltage for Vnb? Im on air, but also with MOSFETs in mind. Im now at 9x285 for NB, but I'd like to get it to 10x285. I need about setting 15~16 for Vnb on this speed (say 1.275~1.3V), where should this end if I wanted to get higher with the Vnb?

Also, did anyone try Prime95 64-bit (blend)? Somehow it makes my system BSOD/error while I can run Memtest for 250%+ without issues First time I used Prime95 64, but also nothing seemed to help to fix errors, so Ill just use normal Prime95/OCCDT/Memtest then
