That's strange.
If it continues after you go back with System Restore to before this started or to your latest image backup that is still correct, it's hardware. If it stops then, it's solved, until you repeat whatever you did to cause it.
Hey guys. So in the past two weeks almost every video game I play will lose its full screen and shrink to minimized or windowed. No hardware changes, tried all my virus effects off, updated all drivers, no windows updates pending. Any help would be appreciated. This isn't stuck keys cause I use a controller for some of them.
