Mid 2010 macbook pro panic shutdown

Question

My mid 2010 Macbook pro is experiencing an increasing number of black screen shut downs.. 3 or 4 a day currently.
Often this occurs when the keyboard or mouse is touched after it has been idle for a short period, and sometimes mid use.
Ive tried running without any peripherals  to no effect and carried out basic disc doctor / onyx procedures to no lasting effect.
Any interpretation of this would be a great help.
Here is a crash report ..
thx

You have the MacBookPro6,2—the Edsel of Macs. It may have the logic-board defect that was covered by this recall.
Make a "Genius" appointment at an Apple Store, or go to another authorized service provider, to have the machine tested. The routine hardware diagnostics used by service providers do not detect the fault. There is a specific test for this issue that Apple calls "VST" (for "Video Switching Test.") Ask for it. A "Failed" result means that the fault is present. However, according to reports, some units may pass the test, and yet still be deemed eligible for repair under the program. Your experience may vary.
Print the first page of the panic report, if any, and the support page linked above, and bring them with you.
Note that the recall only applies within three years of purchase. After that, Apple may refuse the service. In that case, you may be quoted a price of about $300 (in the U.S.) for a "depot repair," which involves shipping the unit to a central repair facility and takes about two weeks. For that flat fee, anything found wrong with it should be fixed, not just the logic board.
The model was discontinued on February 24, 2011, so the recall has nominally ended. Some units may have been sold after that date by Apple as refurbished, or by resellers as new, and they might still be covered.
Some owners report that their unit was repaired under the program after the deadline had passed. Others report that the repair was covered by the extended warranty from a credit-card issuer. Again, your experience may vary.
Sometimes the replacement part is also defective, so be prepared for that possibility. If you decide to pay for a new logic board, test thoroughly during the 90-day warranty period on the repair. Some owners have reported that they went through as many as three replacement boards before getting one that worked.
If it's too late for your unit to be repaired free of charge, and you don't want to pay for the service, you may (or may not) be able to stop the panics by disabling automatic graphics switching. To use the discrete graphics processor, you'll need a third-party utility to switch to it manually.
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.
If you're dissatisfied with Apple's response, please keep in mind that no one here represents the company or can help with customer-service issues.
Back up all data on the internal drive(s) before you hand over your computer to anyone. If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.
*An SSD doesn't need to be zeroed.
