I just installed LoL (league of legends) on my computer. The problem is that almost every time after I play the game, it minimizes all my windows which is really annoying. What is worse however is that afterwards other programs do this as well.

Is there any way to fix this? What can cause such a strange behavior??

I recently installed the internet driver. Hopefully that is not the problem because this is the third internet card for this computer. I have noticed that my internet is messing up as well.
