BSoDing Problem (nvidia drivers?)

[redguard117]

I built one of my computers November 2008. The specs are: Q9550, EVGA 790i Ultra, GTX 260 216, 4 gb DDR3 - 1600, WD 640 GB HDD, and a CoolMax 950CUG, and Windows Vista x64. For a while it worked great, then all of a sudden (during Call of Duty World at War) i went to move my mouse and my view changed a little and froze. There was a repetitive tutting sound from my computer, so i restarted. This happened a few more times, almost always in COD WaW and once/twice in other games, like Far Cry 2. Also, after installing the 185.85 drivers (and those later on) i find that my computer freezes on me at times when I move the mouse after leaving it idle. During the 185.85, it often froze at the user selection screen with a few pixel sized artifacts. I'm currently running the 190.62 drivers, and my computer now keeps restarting/freezing randomly. It BSoDs often during nTune too. First time i installed, when i tried to configure power settings (aka fans, clocks, etc) right when i went to the screen after opening nTune where it says i agree to blah blah blah it BSoDed. I uninstalled in safe mode and reinstalled after a few days, then it BSoDed straight on the user screen. I uninstalled in safe mode again thank god, and a month later installed [COLOR=blue ! important][COLOR=blue ! important]BitDefender[/COLOR][/COLOR] trial edition. Computer was amazingly slow, i mean took 30 minutes to load a profile and open [COLOR=blue ! important][COLOR=blue ! important]windows[/COLOR][/COLOR], and eventually (even in safe mode) would not work. I somehow uninstalled BitDefender. This computer is NOT connected to the internet, but just in case i ran ESET NOD32 and G DATA total care 2009 and both showed no viruses/spyware/malware. I also ran CleanMyPC [COLOR=blue ! important][COLOR=blue ! important]Registry [COLOR=blue ! important]Cleaner[/COLOR][/COLOR][/COLOR], RegEasy, and other Registry cleaners. NOne of them has stopped the problem. Im going to attach the errors shown in the Problems menu in Vista for the most recent ones. If anyone can help me it would be AMAZINGLY appreciated. Oh yeah, 3dMark06 and Prime95 show that my hardware is rock solid, so i don't think its the PSU or CPU or memory. I haven't played COD WaW for a while so that freeze with the repeating noise hasn't happened for a while, but after COD Waw it started showing on my desktop, so i changed the ACPI settings in the BIOS.

The problem happened on two separate video cards, an 8400 GS and a Zotac GTX 260 OC so i don't think thats the problem. ALL of my fans run at 100% so i doubt overheating is the culprit, and nvidia system monitor shows fairly decent temps with my CNPS9700 and the gpu fan. ANY help whatsoever would be appreciated.
