Windows 7: Games crash on change of resolution when in fullscreen

I have just built a new pc and installed windows 7.

Whenever I go into a game it crashes. There is no BSOD dump. I found this happens when it tries switching screen resolution while in fullscreen mode. If I run a game in safe mode or windowed mode they work fine. (After a crash I can't alt-tab or ctrl-alt-del etc but if I hit the sleep button and turn it back on I'll be back in windows)

The games that will run in fullscreen without crashing are GTA4, Crysis and Mass Effect 2.



Torchlight, Modern Warfare 2, Borderlands and others crash if they are not in windowed mode when executed.

I have an AMD Phenon 2 with nVidia GTX275. DirectX 11 in 1920x1200.

I have tried updating DirectX and my nVidia drivers but so far nothing works.

Um, have you removed the video driver completely and installed a fresh copy?

Nope, I'll try tonight.

I read through the FAQ here about fullscreen games and DirectX 11 etc but nothing helped, I did learn a bit though. Just so you guys know I did look for myself

Just tried it, no luck. Same problem.

click on your games launcher and try change the compatibility mode. so far ill play the games that you listed without any problem.. im using ati 4850 and intel core 2 quad.
and when you say nvdia,did you have your physix installed?
