I have a problem that's never occurred before. In the majority of games, part of textures are flickering and some weird white points / lines are randomly appearing on black textures. I already reinstalled the drivers, etc. but it didn't help.
Do you have any idea what it could be? Do I have to reinstall the whole system?
I have a laptop with i7, 8gb ram, radeon 5850 mobility and 7200 rpm hdd's.
UPDATE: this is the video, so you know how it looks like:
Anyways, you have you set the youtube video settings at HD at least, below 720p it is blended. I recommend 1080p
