Seems like the video card is overheating or something.

It was fine last night... kept my iMac online, came home.... loaded Eve... And now I get white dotted lines that go accross the screen occasionally.

Very odd and annoying. I've rebooted. I've reinstalled drivers, you name it...
 
I get this too while loading no graphic intense program. I get white lines randomly and sometimes my screen will go black but windows is still on. I hope this is a driver issue not a hardware issue.
 
One way to check if it is a heating issue is to use the driver's control center software to underclock the card and see it you still have the problem.

I've seen similar results playing HD video in Windows on a PCI Express HD 2400Pro card that was definitely not overheating...
