  1. Yep, Thats the video card going nutts, usually after overheating. Beyond this, each char should have a coloured backgroud, like red, or yellow.

    If you are only seeing one char at a time, and not a long string, then I dont know what it is. Send screenshot.
  2. I had the same thing just happen to me, one letter at a time.
