MBP reboots at random, & freezes up at other times

[stevhop]

I have a circa 2007 MBP. Logic Board and Battery have been replaced, other than that no problem. Just recently it has started to reboot itself at random, I can't pin it to any particular activity. It has also froze up on me about 4 times in the last month and requires that I shut it off and then on again (hard reboot?)

Mine reboots at random as well. Lately the screen will start flickering and completely locks up. My logic board has been replaced once. Once the new mbp comes out I'm getting rid of this piece of crap.

Sounds exactly like what mine is doing. Have you taken yours to an
Apple store? I would but there are no stores where I am.
