Hello everyone. After I play a PC game for a while, the game will automatically switch to window mode. When it does this I can't do anything. I can not bring up other windows or alt tab, the only thing I can do to get my PC to be responsive again is to ctrl alt delete and sign out of windows and back in. It can't be my temperatures since they are well below average and I have awesome cooling. Any ideas? Thank you!

Edit Reason: This is only happening with Far Cry 4 so far though. Should I be worried? Maybe I should of done more testing before making a post. Don't know if it could be my graphics card? It is a Gigabyte G1 gaming gtx 980.
