Weird Virus???

[JSKILL]

Hey i have finally gotten my computer up and i am runnin sygate firewall and adaware...but if i dl something or lev com on awhile when i am not here it jus restarts. I saw it one time and it was the NT Authority Error. I know this is associated with blaster, but it says i dont have that. I scanned with symantec online and some panda scan and Adaware. Know of any virus that could cause this? Its really weird.
