Bonsoir,
 
J'ai acheté mon PC en juin et depuis 1 mois celui-ci est vraiment lent.
 
Configuration : Pentium 4 3.2Ghz
1 Go ram
nVidia GeForce 6800
 
En effet, je constate quand je fais ctrl + alt + suppr que le UC de mon PC est constamment à 50 % voir plus alors que je ne fais strictement rien. J'ai passer un coup d'antivirus + Ad-Aware SE mais rien du tout.
Je me suis ensuite dit que çela venait plutôt du ventilateur mais finalement pourquoi çela marchait avant et plus maintenant? J'ai donc opter pour le problème de registre. J'ai donc télécharger HihackThis et j'obtiens çela !

Merci de me répondre et bonne soirée.

Ta pas un processus qui utilise 50% quand tu les classe sur CTR+ALT+SUPP?

non

Dans le bios tu dois avoir la fonction Enhanced Intel SpeedStep Technology (EIST) d'activé qui permet de baisser automatiquement la vitesse du cpu

Comment faire pour l'enlever ?  
 
Merci beaucoup de me répondre
