MacBook Pro repeatedly freezes, often with odd display glitches
I have an older MacBook Pro, 17-inch which has begun freezing repeatedly.
If I boot into Single User Mode it does not seem to have the problem,
however booting regularly, to the Mountain Lion recovery partition, a
disc, or any other graphic interface I get this hang. This is often before
the machine has booted completely.
At other times it will repeatedly reboot.
I have reset SMC and PRAM, and run fsck -fy on the drive.
I should also note that the machine generally kicks up its fan pretty
quickly and runs very hot, back when it ran, so I am suspecting
overheating, perhaps brought on by the video demands.
Does anyone else have a guess at this and/or another diagnostic step?
