NV4.disp.dll

I got my new PC about a year ago, and its never failed me until recently..

I've been playing Cod: MW2 like an addict, but recently I've started to BSOD after a while of playing (About 10-15 minutes into the actual gameplay)

I read the BSOD and the only thing that made any sense to me was "NV4.disp.dll" Is it a bad driver?

Some help would be greatly appreciated.
