You have the MacBookPro6,2—the Edsel of Macs. It may have the logic-board defect that was covered by a recall program that has now ended.

The model was discontinued in February 2011. It's now classified by Apple as a "vintage product." That means Apple will most likely refuse to fix it (but see the exceptions on the linked page.) In that case, you would have to go to an independent service provider. The part may no longer be available, or the repair may not be cost-effective.

Often the problems start after an OS upgrade. If the upgrade was recent, and you have backups, then you can revert to a previous OS X version.

Otherwise, make a "Genius" appointment at an Apple Store, or go to another authorized service provider, to have the machine tested. The testing will be free at an Apple Store—unless Apple refuses even to look at the unit, which it might. The routine hardware diagnostics used by service providers do not detect the fault. There is a specific test for this issue called "VST" (for "Video System Test.") Ask for it. A "Failed" result means that the fault is present.

If you do decide to go to an independent service provider, be aware that the replacement part may also be defective. Some owners reported that they went through as many as three replacement boards before getting one that worked. Don't expect any help from Apple if you're charged several hundred dollars for another bad logic board and the provider won't replace it again.

If you don't want to take that risk, or if you don't like the price you're quoted, you may (or may not) be able to work around the problem by disabling automatic graphics switching. To use the discrete graphics processor, you'll need a third-party utility to switch to it manually.
