Not sure if this is the right section to post this in since I'm not sure what the problem is.
Whenever I watch videos on youtube or other video sites, it may occur that my screen will be completely filled with lines and start to flicker. Sometimes closing the webpage (by using alt+f4) will return it to normal, but other times I need to turn off my PC completely.
At first I thought it was some driver issues, but recently I formatted my PC and updated to the latest drivers (Radeon 7970) and it still happens.
Also, if I take a screenshot, the screen is normal.

Anyone know what the problem is?
