Mon PC se bloque sur le bureau

Bonjour,

Voilà mon problème : depuis ce matin, mon PC se bloque au niveau du bureau lors du démarrage. C'est à dire que je peux bouger la souris, mais que toutes les icônes sont inactives. En revanche, je n'ai pas de problèmes en mode sans échec.
En parcourant les forums de gens ayant eu le même problème, j'ai vu qu'on recommandait souvent le programme hijackthis pour analyser le problème mais comme je suis nulle en informatique je suis incapable d'interpréter.

Voilà ce que ça dit:
