Ordi qui rame

Bonjour,
j'ai un probleme avec mon ordi (hp)... il met trop de temps a ouvrir les fenêtres, et rame beaucoup... j'ai fait un nettoyage de la tour (poussieres) et fait des analyses avec mon antivirus (avira), ccleaner et spybot s&d.. mais rien n'as changé, l ordi plante toujours...
j'ai donc fait une analyse avec hyjackthis..
je poste le rapport si quelqu un souhaiterais m'aidé.. merci d'avance
