Réactions lentes et blocages intermittents

,
Bonjour,
Mon ordi devient de plus en plus lent, se fige par moments et repart. J'ai appliqué la procèdure indiquée dans le forum mais c'est toujours pareil. Je post donc ici les 3 rapports générés après analyse. Que faut il faire pour solutionner ce problème?
Merci
