Driver related BSOD and unwanted behavior (memory leak)

[h3x]

I have an Nvidia 9800 gtx+ in my machine which is the only part that is old. I suspect this or its driver to be the culprit for frequent bluescreens citing "IRQL_NOT_LESS_OR_EQUAL". In addition, the driver-related process NVInstEnabler.exe goes on regular memory-eating sprees hogging most of my 16 gigs of ram.
What's your opinions and experiences with graphics driver related bluescreens and other annoyances? Did you do something that solved the problem? Any recommended course of action short of buying a new card? (I'm saving up for a Radeon 7950 or better)

look like you may need a good virus check or do a malwarebyte and retest yuor nvidia driver they could be corrupt http://www.processchecker.com/file/NVInstEnabler.exe.html

The page you linked to is a generic report. NVInstEnabler is not a worm/virus, as I've checked that. There are others I found through google who have experienced the same. I have also contacted NVidia support, to no avail.
