OS crashes often relate to apps misbehaving. I would start off clearing the crash log so all of the old stuff is removed. Then the next couple of times it crashes save the log so you can send it to Apple as well as see what is going on. I would make sure all of the updates for the OS & all of the apps have been applied. I would also remove anything I didn't need from startup and Login Items in the User account. You might want to boot up your system on an external bootable drive so you can run Disk Utilities on your internal drive. I would also recommend running the built-in diagnostics so see if something shows up their. To do that, when you start your system after the bong press the '''D''' key.
