Windows 7 qui se fige en mode normal

Bonjour,

Je vous contacte car j'ai mon ordinateur portable qui se fige entre 2 et 5 minutes quand il est en mode normal.
J'ai une connaissance qui m'a demandé de voir si après avoir fait une restauration à un point antérieur, tout remarchait, or ce n'est pas le cas...
Le problème c'est qu'il fonctionne bien quand il est en mode sans échec (on m'avait dit aussi que ça aurait pu être un problème de carte mère vu qu'il a 2/3 ans).

Je vous poste en même temps ce que hijackthis m'a mis si ça vous aide pour me sortir mon ordi de ce problème:
