    I have a MacBook Pro (17-inch, Mid 2010) Snow Leopard 10.6.8 with 4 GB of ram. I have 344.46 GB of space left on my HD.

    This problem would only happen very rarely before it became more frequent. Usually I'll be in the middle of doing something in Photoshop and the screen will turn black. The key board lights remain on, but there's nothing I can do to get the screen back so I have to hold down the power button to shut it down and boot it back up. Usually it happens 5 or so minutes after I boot up my computer.

    After I boot it back up it gives me the option to send this error info to apple:

    I tried resetting the SMC, it turned off again 10 minutes after turning on the computer. I sometimes connect to another older mac via wifi on a home network, could that cause the problem? What's mystifying is that the problem has suddenly got worse, what could I have done differently this past month to cause it to act up? I'll try a hardware test next, I've done hardware tests awhile back on this mac, and nothing's come up, though.

    EDIT: I did an extended hardware test and it said no troubles were found. I've been told it can miss things, but I guess it's not that big of an issue if it didn't come up with a logic board and graphics card problem?
