I have had hard crashes and reboots since updating to 10.8. Did a Clean Install just in case but every one in a while I come back to my mac with the message saying that the computer has rebooted.

Any or all of the following third-party system modifications may be contributing to your problem:TrustedData driverAttotech driverLogitech Control CenterLittleSnitchCalDigit driverI suggest you uninstall all of them according to the developers&#x27; instructions, reboot, and see whether there&#x27;s any improvement. If there is, you can experiment with putting them back, one at a time, to identify which one is at fault.If there&#x27;s no improvement after making the suggested changes, post again.
