Virus ??

Bonjour à tous, voila mon problème que j'ai essayé de résoudre par tout les moyens possible. Depuis quelques temps mon pc me fait des freezes puis redemarrage dans des laps de temps tres differents et celui ci rame tout le temps. Donc test antivirus, Ccleaner, Spybot etc .. aucun changement. Certitude ce n'est pas mon pc qui chauffe plusieurs test effectués je ne monte pas au dessus de 60° et j'ai de tres gros lags et le pc rame beaucoup trop, d'habitude mon pc tourne au environ de 60/70 image par seconde alors que maintenant celui ci ne tourne qu'a environ 20 image par seconde en plein jeu depuis les debits de mon probleme, point de vue latence aucun probleme. Voici la config de mon pc carte mere crosshair formula III, carte graphique asus en 9800 gtx+ dark knight, 4 GO ddr3 OCZ black obsidienne 1600 mhz, processeur AMD phenom(tm) 2 X2 550 3.1ghz , carte son asus supreme FX X-Fi. Mon pc tourne sous vista familial premium 32 bit. Par tout hasard je vous joint le scan de HijackThis car je ne sais pas l'interpreter. Cordialement .
