SERVICES.exe Has Generated Errors

The last couple of days, my computer randomly gives me an error messages that says SERVICES.exe has generated errors and will be closed by Windows.You will need to restart the program.An error log is being created.Then, a shut down box pops up that tells me my computer will shut down in one minute... and there's a timer on there that counts down and when the minute is up, my computer shuts itself down and restarts.I've run Adaware, Spybot S&D, SuperAntiSpyware, and cleared my temporary internet files, etc. It's still doing it, and it's getting on my nerves because I can't get ANY work done. It's doing this like ever 30 minutes or hour or so.
