Persistent grey screen on startup.

I own a late 2011 MacBook Pro running osx mavericks. Had it for two years with no problems. In early January of this year the macbook would crash whenever I opened photoshop or other programs like iMovie or photobooth. The only way to get it to function again was to hard restart the laptop. And Even then sometimes I would get the grey screen on start up and hear three beeps. I Went to the Genius Bar and the employee reseated the RAM and the laptop functioned well for a week. When the persistent grey screen appeared again, the genius employee erased all my storage, with my permission, reset my operation system completely. Even still I get the grey screen and the laptop doesn't make it to the login. What should I do to fix it? Would buy info new ram solve the problem? If tried pessimg shift and running in safe mode but I just get a blue screen and am forced to hard reset.

MacBook Pro (15-inch Late 2011), Mac OS X (10.7.5)

I suggest you take it back to the genius bar before you spend any money.

The repeating 3 beeps is a RAM/Memory problem. So it seems that you have either bad RAM or the sockets they go into are failing.

Bad part is if it is the sockets the only way to fix that is to replace the logic board. Which is expensive.

You could try new RAM (if you do buy it from Crucial.com) but if that doesn't fix the problem then it is the RAM sockets that have gone bad.

Heat can cause RAM to fail. Same for the sockets/slots. Excessive heat can damage many things in a notebook.
