Macbook Pro randomly restarts all program

Question

Hey Guys,
I have a MBP 15 that for no apparent reason while I am working the screen will turn blue, and then all the services seem to restart (All the apps close and then re-open). The computer doesn't actually restart just the services. It happens about once a day.
The computer has a new battery and is plugged in when this happens.
The laptop is sitting on a laptop cooler which is blowing air on it.
I do have a  Momentus XT hybrid drive, which I am thinking may be the problem see:

But that drive is fast, it boots up somewhere between 15-35 seconds.. crazy fast but the services restarting is the only problem I have been having with the MAC and I don't know if its the HD, an application I have installed, or what.  Maybe you guys can shed some light or help me figure out what errors I might have that might be causing it.
The laptop restarted all the service after 1:34pm , below is a portion of the log file...there is a ton more but didn't know how much to post to be helpful.
I have tried repairing the disc, fixing permissions and rebooting...but the problem still returns. That is about all I have tried so far...
Any Suggestions???

Answer 1

The first thing I'd do is create a new user account (call it Test Account) and leave it absolutely pristine. DO NOT change any settings or add any software. Then log into that account and see if you have the same problem. If you do not then you have eliminated hardware and also know it's a software problem limited to your current user account. That's were I'd start.
I'd also recommend opening Activity Monitor (Applications - Utilities - Activity Monitor) and see if there are any applications taking up a lot of %CPU and how much free RAM you may have. If you see an application taking up too much %CPU then you have narrowed down the issue. If you are extremely low on RAM then perhaps a RAM upgrade is what all that's needed.
