Iam unable to play games they get minimised as soon as i try to pay them

when they minimize, do you get any kind of error?
what happens when you try to restore the window to the normal size?
what game's specificly?

Try Alt+Tab to get back into game.

Sounds like a graphics crash of some sort, check your logs and run dxdiag.

Need more info: post specs for the laptop (make, model, RAM, GPU, CPU, +driver versions). Is it running switchable graphics?

specific games or all games ?
are any background apps runing like antivirus / etc ?

Games downloaded from where, more importantly...

Doubt the OP will ever come back and give anymore info about his issue. If he did might be easier to diagnose the problem.

be nice to know if his computer is even capable of playing a game.

I just want to know if they were pirated games...
