Some bugs to iron out...

Hi,
So I recently finished working on my first ever gaming PC, and I am pretty happy with the short-term results. For example, I can run any games with graphics set to high and not have to deal with framerate issues or other such bothers.
However, there seems to be a few major problems which have been bugging me to no end recently. Whenever I run a game from Steam (HL2, Portal, Fallout: New Vegas, etc.) I am able to play for a while on any graphics setting, and then after 3-20 minutes (Depending on the settings) the game with crash, quit and show an error 'bubble' that says: Display Kernel Driver xxx.xxx has stopped responding and has successfully recovered'.
Anybody have any ideas? This has become extremely frustrating and is stopping me from using my PC for what it was built for. I have an nVidia 480m GPU, Dual core i3 Intel processor, 4GB of RAM and Windows 7 (Basic, I think) 64 bit.

Another frustrating bug that could be related is the world sometimes glitching out, textures become bright block colors and then the game crashing with a sound loop. I can get back to the desktop using the windows key, but cannot close the window and need to force restart. This happens most often with HL2 and New Vegas, both open world based games.

If you have any way of helping me it would be much appreciated, and thanks in advance to anybody who can figure this out.

Also, my drivers are up to date.

Thank Y'all :]
 
Have you tried rolling back your drivers a version or 2? Sometimes they can be incompatible. Check the temperatures also. Think the nvidia tools will have that option?
 
as phillydee says roll back your drivers, especially if you have recently updated them. a quick look round google and nvidia's forums brings up a few simialr issues and a lot are resolved by changing drivers.

edit. if its greyed out in the device manager you could probably just search for an older driver from nvidia's website and download and instal directly
 
Not so much a rollback (And it is greyed out as you need to elevate it).

Uninstall current drivers, and reinstall a previous version.
