When did this problem start, did you add any hardware or software recently, do you get any errors or blue screens of death?

Start it up and if you think it's about to shutdown, hit start - run - type "shutdown -a"

You can try doing a ctrl+alt+del to bring up task manager. Then go to file>New task> type explorer.exe. Hopefully this will bring everything back to normal.

You should also think about installing SP2 for extra security.
