So I see lines when I have a game open,not in the game tho.Its only on my main monitor that the lines appears.

System specs? If it's only appearing in 2D ... maybe 2D memory clocks are too low.

Update your gpu drivers, or reinstall them, this will fix the issue.

I have to agree, do a thorough uninstall and then reinstall the drivers as a first step.
nice method for making sure you're starting from scratch;

You know how to download and install new drivers from Nvidia so I'll skip that step.
