Hi there,

When I try to watch online videos in websites like youtube everything goes fine, but when I try to play it in full-screen mode it plays slower and the sound become very noisy... The issue is, when I try to play a games like stalker the same situation happens, It's not completely stuck but the game is more slower and the sound is not clearn.

I don't know what is the problem is this, and my system runs windows 8 home basic 64bit
sound card is realtek and the video card is 8800GTX. If you know how to fix my problem please reply me. Thanks!
