Just reformatted with xp. i get a window that pops up with the following message: This system will shut down. log off and save all information. initiated by NT/AUTHORITY/SYSTEM.
system process: C:\...system32/lsass.exe
status code 107374819
there is a countdown from 60 seconds

This is an old WORM that was spreading around the internet. You need to get your machine fully patched with all the windows update patches, or load XP SP2 on it.
i ran virus/ worm scans and nothing comes up. is this common with this tye of worm?
Blaster Virus, less then 20 mins. on the net and you will be infected if you done have your system patch. Download a free fire wall install and then get all your updates.
