         Hi Robert
             Lots of things may cause. What you have to do is collect as many feedbacks as possible to track the issue.  Check the eventlogs, the Blue Screen messages if exist, turn of auto reboot to see BSODs. Think about reverting your latest actions.

    Check the capacitors onboard the motherboard for leakage and bulging.

    Heat and power supply issues are often the cause.

    Like said above, there are many possible causes:
    - Memory error
    - Bad sector in hard drive
    - Spy or Virus
    - Overheat
    - System board failed (like bad caps), etc.

    You should have or see some kind of error message so that we could help you more to id the rootcause.

    goto control panel - open administrative tools
    double click on "Event viewer"  - check the logs to see if it detected any problems or why it rebooted.
    (click on each type - application,security....) and read on the right
    it could be a device driver update from microsnot.  usually the ATi graphice card

    A virus infection can do this also, check your system for viruses

    I'm going to start by checking for viruses. If that doesn't do the trick I will proceed to some of the other software related suggestions before messing with the hardware.

    The badcaps check only requires taking the cover of and looking. It would be worth the short time it takes to do this first, and you don't have to mess with hardware other than the screws holding the cover on.
