Picture messes up with two monitors

I bought a used fullscreen monitor (DVI-D) To add to my other flat fullscreen monitor (VGA) and have two desktops for better multitasking. It was working just great until a while ago, part of one desktop showed up on the other screen and horizontal lines appeared. If I reset the settings for having two desktops it appears fine for about 20 seconds, then the same thing.

The eyefinity guide says to stay away from VGA but I'm not sure if this is the problem since I'm not using eyefinity.

If you could help, my video card is a HIS Radeon HD 6850.
Another thing, my drivers are up to date.

I can't switch the output, since there's one VGA and one DVI output. But if I use one monitor separate from the other they both work just fine.
