when it starts the 60 second countdown do:
start -> run and type: "shutdown.exe -A" (no quotes) that'll stop the 60 second countdown and shutdown.
okay, it's either the sasser worm or ms blaster worm (if it is in fact a worm) - if on start up it mentions "LSA Shell (Export Version) then it is the sasser worm and you should get these:

if not then it is msblaster and you should get:
http://www.microsoft.com/security/incident/blast.mspx
that patch.
and run:
http://securityresponse.symantec.com/avcenter/FixBlast.exe
to scan and remove the worm already present.
Time.
