Hello admin i have just played with my brother on full graphic(everything was on high) everything worked perfect! and smooth!.

But now that i have played with him after 30 minutes i get my screen freeze every 5 seconds.
Please tell me what to do? and dont ask for my Graphic card cause as i said everything worked perfectly for 30 minutes.

and I closed all my progrems even the google chrome even Teamspeak everything! but i keep geting this screen freeze( and its not FPS) its just that the screen is freezing.

Tell me what to do?
