PC låser i ca. 2 minutter

Jeg har et underligt problem med min PC. Ca. hvert 10. minut går min PC næsten i stå, dvs., at den arbejder meget meget langsomt, hvilket gør den umulig at bruge. Dette varer ca. to minutter, hvorefter alt er normalt igen. Efter 10 minutter gentager problemet sig. Jeg har prøvet at lukke for antivirus og firewall, men dette hjælper ikke. Jeg har windows 2000. Jeg har før reinstalleret min PC uden at problemet har været der. Jeg har tidligere kørt en hijack log og fjernet et par spywares, men nu er den gal igen. Nedenfor følger en Hijack log - nogle ideer?.
