HijackThis log - Hvorfor genstarter maskinen uopfordret?

Jeg er ved at prøve at indkredse hvorfor min computer ind imellem genstarter uopfordret med efterfølgende besked "Systemet er genoprettet efter en alvorlig fejl".
Det sker også efter at jeg har Fdisket, nyinstalleret XP + SP2 og installeret de programmer jeg nu skal bruge. Jeg har ikke mistanke om nogen virus- eller ormefejl, men er der en der lige vil tjekke min HijackThis log alligevel?
