Vista - Driver Failure.

I have a problem with my PC. It's worked fine for a few months now (it's new) but all of a sudden I'm getting 'nvlddmkm driver' failures which were simply making my screen blank out until it recovered. But as of today it's causing whatever program I'm runnning to stop responding (inc 3d mark advantage, if I try do a Graphics card test) and it will only run for 2-3 minutes at a time. I assume the problem has arisen with a Vista update (I run Vista Ultimate x64). I have visited NVIDIA site and downloaded latest drivers for my 2x NVIDIA GTX 285's, and double checked windows updates. I've also read alot of forums all of which seemed to be rather old and with no real solution or definative cause.

What can I do?

Hi Morphs, I have not had this problem so i can not help you personally but i have been following this thread Vista graphics card crashing that may be of some help to you in the meantime time till someone can assist you, just click on the link, hope you have some resolution.

Nvm, think i got it. Suspect it was virus related. My anti virus had expired (Still running free trial period from new PC purchase). Apon updating, detected a nasty little bugger. Deleted it, defragged and found an option in widows menu to enable new drivers automatically (which was a recommended setting but not checked). Completed a full graphics card test and games have run fine so far.

Thanx anyways.
