My MacBook Pro crashes to black 3 to 4 times per week
My MacBook Pro, circa 2010, crashes to a black screen 3 to 4 times per week, but can also crash twice in one day. It's Mac OS X, version 10.6.8, 2.66 GHz Intel Core 17, 4 GB 1067 MHz DDR3.
It doesn't restart itself, and I don't hear any beeps. It also doesn't shut completely down -- just goes to a black screen. I have to hold the power button to shut down, then restart. An error log comes up at the restart asking if I want to report the problem.
Should I take it in, or is there something else I can try? I've been running MacKeeper, but that doesn't help much.
Thank you!
MacBook Pro (15-inch Mid 2010), Mac OS X (10.6.8)
