|More than likely the graphics chip is overheating. Make sure the inside of the computer tower is dust free & all the fans are working properly. If it needs to be cleaned, make sure to unplug the power cord 1st, but do NOT use a vacuum because of the chance of a static discharge. Instead, use compressed air & a soft brush. If the inside is really dirty, you may want to completely disconnect everything & take it outside for cleaning.|
