Your computer is probably overheating.

Turn off the computer, remove the case and make sure that the graphics card and/or processor fans are running. Also, remove any fluff and dust by using a small vacuum cleaner nozzle or air duster. Be careful when cleaning that you don't make the fans spin too fast and damage them.
