Applications que ne se lancent pas

Bonjour,

J'ai un petit problème depuis peu : je lance une installation d'un petit logiciel (musicmatch ou winrar ou ...... bref rien de très spécial) et ....rien ! sablier 2sec et rien. Par contre elles apparaissent dans le processus ! Certaines autres applications fonctionnent ! bizarre d'autant plus que ma config vient juste d'être installée !

Ci joint (au cas où) mon scan hijackthis
