Ordi trés lent

Bonjour,
Voila j'ai un souci avec mon ordi, pourtant j'ai passer ccleaner, tunesUp, j'ai fait une défragmentation, j'ai Gdata comme antivirus, je sais qu'il ralenti un peu, mais là toutes les 3 secondes, les programmes se stopent puis reprennent, c'est lassant à force
Processor 1.70GHZ
0,99 Go de Ram
Mon espace disque est trés peu rempli

Voici le rapport HIJACKTHIS
Si vous pouvez m'aidez ca serai vraiment super merci !!!!
