Problems playing games with NVIDIA 9500GT

Guys,

I recently changed my os to WIN7 x 64 I was upgrading my motherboards/ram & cpu but didn't do the graphics as Im not a huge gamer. Sibe I have done this not one game other than those built in will run for long. I get about 5mins in then a crash and the message games has stopped working. I have chopped anmd changed drivers umpteem times but to no avail. I have a phenom ii x 4 3.2ghz, 4x 1600mhz kingston ram, 500w PSU and the card as stated is an Asus 9500gt 1gb ram. Can anyone tell me what could be causing the problem and how I identify for sure what it is. The games I am trying to play are F.E.A.R 3 and hunted the demons forge.

tx in advance

Download and install this display driver.
Note: use custom install, and uncheck HD audio driver, if possible check 'perform clean install'.

Hi thanks for replying so quickly I am in the process of installing and have the options open there is no HD audio option.

Graphics driver
3D Vision controller
3D Vison Driver
NVIDIA update
Physx system software

& the clean install option is there, am I missin something?

Thats ok, the first is needed now, but you can install the others if you feels them necessary.
I don't recommend nvidia update...

Ok mate thanks I will give that a wee test and see how wee go and report back.

Cheers

Tried it there a couple of time seems a little better but this time rather than going all pixelly and freezing it just cuts of and goes back to windows, but still there after a minute or two.
