Hey, thanks for the advice. Didn't quite fit my situation, though. The first dealt with actual lock-ups and the second with Windows 8, which my kid (owner of the machine) doesn't have.

I'd like to help you identify and resolve this issue. I have found a document for you to use. I understand the issue you have may not be the typical lock up or freezing some customers speak of, but I think this will be helpful. Computer Locks Up or Freezes in Windows 8.
Here is another helpful document > If Windows 8 suddenly restarts without warning, or restarts when you try to shut it down, it may be caused by one of several issues. Windows could be set to restart automatically when certain system errors occur. This feature of the Windows 8 operating system can be disabled. A BIOS update can also resolve the issue. Use the information in this document to resolve issues with the computer restarting unexpectedly - The Computer Restarts Unexpectedly.
I hope this helps.
