WindowServer causing MBP to freeze/crash?

For some time now my 15" MacBook Pro has randomly frooze or restarted itself without warning. It does this while running all different applications from Photoshop to just Safari. I have checked Console and this is what it says right before a freeze:
12/28/10 8:38:14 AM com.apple.launchd.peruser.501[148] (com.apple.Kerberos.renew.plist[182]) Exited with exit code: 1

Any help on what to do would be greatly appreciated!

CleanMyMac? Why? I would remove that app and see if your problem goes away.

Is CleanMyMac harmful to Macs? This is the first I have heard anything about someone pointing to this application.

Well, it was the last thing that ran before you had a problem so I would start there. Why do you think you need CleanMyMac? Macs are not Windows and most of those things can be done with a simple reboot.

Okay, I uninstalled CleanMyMac. Is there anything else that could cause a MacBook Pro to freeze/ restart randomly?

I don't think so at this point. I would reboot and play with it for a while to see how it goes. If it doesn't freeze then you found the culprit. The problem with things like this is that troubleshooting is hit and miss.
