uvman, I've been having the same problem as yours. The nvmcp wash BSODing randomly with err'tee'hmm... drivers. I spent hours in finding where to locate the problem. I finally found a q&d fix by installing RC1 beta drivers. The perfs are not that much great but the driver just works. Since I reverted to this version, I only got 1 BSOD by stressing much vista. I guess you'd like to try this: http://www.nzone.com/object/nzone_download...ta_x86_rc1.html hope your bsod's won't last cheers
