I'm at a complete loss for what's going on here--any guidance in troubleshooting is greatly appreciated.

Two seemingly related video card problems. First, and less serious, is that when viewing a web page with lots of white space I get a flicker that is slight but definitely noticeable. If I scroll down one click, it disappears. Very strange.

Second, and more serious: My computer has been suffering from what seem to be video-related crashes for about the last month here. Started when trying to watch an embedded video on Twitter--computer would lock up, with the screen garbled by horizontal artifacts, only fixable by a hard restart. Now it does it also about a fifth of the time after a hard restart in combination with launching chrome. Also happens maybe once or twice a week just working in windows in Word or Excel or something.

I've updated to the latest drivers, and made sure I'm running the latest version of DirectX. GPU temps are fine.
