My Mac (MacBook Pro, 10.7.3 OS) is crashing a couple of times a day. I started this behaviour just recently, and for no apparent reason. I've done a disk check and it all seems fine. When it crashes, the screen goes black and I have to long-press the power button to force a restart.

When the Mac restarts, I get prompted to send data on the crash to Apple. Is there anything in this data that would indicate to me the cause of the problem? Faulty IO board, memory parity corruption, disk problems etc?

This is one of the recent reports:

Yes. You can google for selected parts of it to see what others have written. Besides that, it's very low level technical information, and if you have to ask this question, probably not helpful to you. You could add it to your question (indent all lines by four spaces for monospace text, maybe it's something one of the other users here has seen before, or has an idea what you could do. –  Daniel Beck Feb 10 '12 at 14:45
