Windows 7: Command and Conquer Generals ZeroHour, Minimizing problem help ):

Every time i play this game, the screen would randomly go black, then it would return back to the game, then a few min or seconds later it would minimize itself, and it would repeat this process over and over again to the point where it's excruciating annoying and unplayable... This is one thing i really hate about technology, because when i first played the game it ran absolutely fine, but the more i played it, this problem just randomly happened without me doing anything or changing anything.. I already re installed drivers updates like a million times, unfortunately i have ATI cards and AMD hasn't release any god dam driver update since the twenty second of October... Any suggestion?
I run Window 7 home premium
dual 5970 Ati Radeon
920 i7 processor 2.6ghz
Hardrive 1.15TB
