whenever i play CSS my screen freezes. i cant do anything, it freezes in one spot and constantly loops the sounds that was last played. the only thing i can do is hit the windows key (which brings up start menu) then hit the up arrow (bringing me to "turn off computer") then hit enter and hit left (Stand-by) i have memorized this key pattern cause it happens so much. then when i turn the computer on again from stand-by counterstrike is not responding so i end task then everything goes back to normal. PLEASE help. it is so annoying especially when i am trying to run a server and everyone gets disconnected.
