Mémoire saturée, accés disque permanent

Bonjour.
Quelqu’un pourrait-il m’aider.
Après plusieurs jours de galère car mon Ordi faisait des accès disque en permanence, j’ai restauré mon PC à un date ou il fonctionnait bien.
J’ai toujours le même problème et en plus ma mémoire vive se sature toutes les 3 ou 4 minutes et tout est bloqué pendent environ 30 secondes. Cela ressemble à un manque de mémoire vive, j’ai fais des vérif. Et tout me parait normal.
Mon disque système fait 35,7Go et il me reste 5,47Go de libre.
Mémoire physique (Ko) Total : 1046576, Disponible : 197952, Cache système : 333340
Il se peut que la mémoire de ma barrette soit défaillante, mais je ne sais pas le contrôler.
J’ai fait un scanne par mon antivirus VirusScan de McAfee et il n’y a pas de virus.
Si une personne en ligne pouvait m'aider cela m'aiderait beaucoup. Merci d'avance.
Sincères salutations,
Jacques
