CPU-brug "spiker"

Hej,
Jeg har et problem med min computer. Selvom intet program er tændt, så kan jeg se under taskmanager(joblisten) at min cpu-brug stiger til omkring 20 - 25 % hvert 3 - 4 sek. Jeg har scannet for virus med Avast og Kaspersky engangsscanner. Jeg bruger regelmæssigt Ad-Aware og Spywaredocter, som ikke finder noget usædvanligt.
Jeg har lige kørt highjack this og smider lige loggen, så hvis der er en som har tid til at hjælpe, ville jeg være yderst taknemmelig.
På forhånd tak.
