Problems going full screen

[antong]

I have been having this problem as long as i can remember, but i finally got the time to ask around.

When i put almost any video in full screen, the video works fine for a couple of minutes, but then the picture starts getting laggy and so does the sound. But when i takes it off of full screen it works fine.
I have checked all updates for my video card, and almost every piece related. I have a GeForce 9800M GTS 1GB.
And i don't think its a virus because i do have a scanner/firewall.
PLEASE HELP!

Try to use different Video Player. Try to put the drivers you have before getting that problem or simply put an old driver on it to test it.
