If your latest fix does not work. Could be the graphics card, or possibly the logic board, you can take it to Apple they will diagnose it for free, and give you a price for the repair, if you decide to go that route. If you are still under warranty, or have Apple Care, they will probably repair for no charge, provided there is no evidence of being dropped or liquid damage.
