nv4.disp.dll probs

when playing some games on my PC, my computer randomly crashes and I get a blue screen of death. It normally happens if lots of stuff start happening such as a load of explosions on FPS or the AI start attacking my base on RTS etc. The screen blames the problem on the file: nv4.disp.dll which apparently is a display driver.

The first thing I did to try and fix it was to download a new driver, but this has had no effect. I also tried going into Safe Mode, deleting the driver and reinstalling it but this too has proved fruitless.

I'd be very happy if someone could give me further advice as the Microsoft website really hasn't been much help

Thanks
