Computer keeps crashing!

[vangkm007]

So I keep getting a BSOD, now the computer starts up only 10% of the time and that's if I leave it alone for a day or two. The error message I get is:

IRQL_NOT_LESS_ THAN_EQUAL

error with the nvstor32.sys

I googled the problem and tried all the recommended fixes, still nothing. I know it has to do with the graphics card, tried updating driver/rolling back driver/re-installing driver nothing...
