I didn't have this problem a few weeks ago but all of a sudden when I try to play a game and switch windows the screen freezes up for 2-3 seconds, goes black and that pops up. It says Windows 8(R) but I am running Windows 7 Home Premium. I have tried using windows update and update everything and downloaded the Intel driver utility thing which updated the Intel HD drivers. It is still happening every 10 minutes. It makes games unplayable which is specifically why I bought this computer and it is only 2 months old. This problem only started maybe 3 days ago. I'll post some information below and tell me if you need more.
