PC qui freeze, rame puis plantage complet

Bonjour à tous,
je viens vous demander quelques conseils et un peu d'aide si possible.

alors depuis deux jours, j'ai quelques soucis avec mon pc, il rame d'une manière peu commune, en regardant les processus/performance certains processus s'affolent de temps en temps

le plus grave c'est qu'après le boot pc, à un temps variable (15 -30 min) le PC freeze complètement, impossible de ctrl+alt+suppr pour kill un process mangeur de ressources, aucun click possible, etc

seule solution, reboot le PC à la "dure"... bouton de la tour... grr

j'ai fais des scans avec Clanwin Antivirus (memoires + virus) qui m'a enlevé quelques merdouilles, Malwarebytes en scan approfondi en a fait de même
Mon antivirus Avira a fait légèrement le ménage mais malgré tout ça le problème persiste

je copie/colle mon Hijackthis ci quelqu'un pourrait éventuellement m'aider
