It may not be that fun, but give this a try:
Click START, then 'Help and Support', then enter "list of troubleshooters"
into the search box then click the underlined result shown on the left....
You'll get a lengthy list of Troubleshooting steps for various problems you
might encounter...
Select the Startup/Shutdown link, then work through the problem.
It'll be sort of like doing your taxes, but at least you won't have to
write a check!
Post back here if it doesn't get you anywhere.
Good luck,
