I doubt that it is voltage issue. Mostly it is either a driver issue, or a hardware issue. So first let us eliminate the chance of the driver issue. Have another version of display driver, say 314.22 WHQL. Uninstall everything, and then perform a clean install as mentioned earlier.
Observe minutely if it is behaving the same with the 314.22 WHQL or not. Let us know.
