Programs in fullscreen Crash to Desktop with no error.

[Shark09]

I'm new to Windows 7 and i have owned asus gaming tier pc for 2-3 months, and this problem came up. I do not know what to do. Do i need to post some information? And some times during the crash, pc losts connection to internet. It's getting really annoying, since i'm tf2 Trader.

EDIT: Now it's doing it constantly, and after some time, mouse and keyboard wont respond.
also, when the crash starts, it sounds like usb being plugged in. it's Freaking annoying.

it effects programs in window too. They look like it opened another tab, wich is really annoying while typing.
