I was having this exact problem in XP (A8N-32 SLI Deluxe, 8800GTX, 4800+ X2) and it was seriously frustrating. Once I got my C2D machine up and running (E6700, P5W DH Dlx, 8800GTX) with Vista Ultimate X86 I "repaired" WoW without having to install it again, and it runs just fine. For the first time since BC came out, I played for several hours without a single reboot, bsod, or crash. I got disconnected a couple of times, but I hear that's a WoW server problem.
