I would first try to see if it could be some sort of virus/Trojan/spyware/etc first. Scan the system for them. I'd do this as an external drive on another working known system.
If nothing is found then look at the Video Drivers. Reinstall the video drivers. If this does not work it could be the video card is giving up the ghost at high resolutions. I've seen this before and it was the Video Drivers in my situation. But, Virus Scan first.
