Unlike nowayspammers I WOULD worry! The frequency you hint at is way
too much for comfort. This is something you SHOULD investigate!!
At the point you want to shut down, check your tasks with
Ctrl+Alt+Del. One of those tasks is causing the problem, it may be a
rogue program which you didn't even know was starting and which you do
not need, or, worse, it could be spyware, a virus, or adware.
Use this site, my favorite, to check what your tasks may be :

For spyware the two best free anti-spyware programs are Ad-Aware and
Spybot. You can get them at
www.download.com.
