Will it boot up into the advanced boot options to try your restore points, although it sounds more like a coincidental graphics problem which the repair program doesn't touch.
If it boots okay into Safe Mode etc. then that would tend to point to your graphics card.
The only other thing I could suggest would be a cold boot where you would switch off and disconnect the power cables then hold the start button in for about 30secs and then reconnect to see if it boots.
