For what it's worth, I was having similar problems, and had almost concluded it was time to change an admittedly old computer (9-10 years). I had decided it was the graphics card overheating. As a last ditch attempt, I took the card out and gave it a thorough clean. This was a good month ago and I've had no problems since... Rudimentary, but effective.
