Yea, so this has been a thorn in my side for a very long time but I just dealt with it so far. So the problem is when I start up a full screen game I.E Cortex, or Battlefield my comp decides it would be OH so very fun to downsize the program as if I was hitting the Windows button It wont stop at just once though, it likes to do this about 30 times instantly every time I re size the game until it finally stops and lets me play the friggin game. This has happened before on my first computer but stopped doing it after about a year but on my newer one (still fairly old) has been doing it for about 2 years now... I figured one of you guys should have an answer so I don't have to pay $50 for Windows technical support.

Might be a prank-class virus.
Also what version of windows?

Update your video drivers, and then come back.

Thanks, I cant do anything right now because I am back at my mom's house so I wont have access to the computer for about a week.

Odin, I will PM you about the results when I do it.
