What antivirus are you running?
This could be virus or antivirus related; event ID: 6008 is an unexpected shutdown event caused by a program or hardware faulting. See Event ID 6008 is unexpectedly logged to the System event log after you shut down and restart your computer for more information (the fix does not apply to Windows 7, but the information is still valuable).
You can also see if Windows 7 has a solution for it through the Microsoft Fix it Solution Center: troubleshooting software issues tool.
