Sounds like you may have been bitten by the MSBlaster worm or the Welchia
worm.

Have a look here for information about the Blaster worm and its variants:
http://www.microsoft.com/security/incident/blast.asp

And here is information about the Welchia worm:

l

You need to d/load and install Security patch KB824146, available here:
http://support.microsoft.com/?kbid=824146#WinXP

Also, d/load and run the Blaster worm removal tool:

oval.tool.html
and the Welchia worm removal tool:

Your computer is now infected with the W32.Blaster.Worm or
one of its variants. This happened because you have not
been using an internet connection firewall and have
apparently neglected to install the critical updates
available at the Windows Update website.
-----------------------------------------------------------
-------
If your computer is constantly attempting to shutdown
or reboot, quickly go to:

Start > Run and type: CMD , and hit enter.
This opens the Command Prompt window.

Then type: shutdown -a , and hit enter.

This should halt the rebooting problem.
-----------------------------------------------------------
-------
Then immediately turn-on Windows XP's built-in Firewall:
http://www.microsoft.com/security/protect/
(To enable the built-in firewall, go to:
Control Panel, double-click Networking and Internet
Connections, then click Network Connections. Right-click
your connection, then
Click Properties, and on the Advanced tab, click the option
"Protect my computer and network..." Note: the built in
firewall only monitors incoming traffic not outgoing (ie
spyware, trojans, etc.. you may have on your system).)

Special note if you use AOL:
America Online installs its own connection settings that
override
the ones that come with Windows XP. America Online's
connection settings don't include a way to turn on Windows
XP's
built-in firewall.
