[XP] winlogon.exe redemarrage

Bonjour, voici mon problème depuis quelques jours je recois ce message d'erreur : http://img489.imageshack.us/img489/1719/bugxe2.jpg
Tout d'abord je recois un message de Sygate puis ensuite la fenêtre du bas et quand je la ferme un message se met comme quoi l'ordi va redemarrer automatiquement dans 1min puis le décompte. Si je fais OK le skin "xp" disparait alors qu'un skin basic se met puis l'ordi s'eteind.

Voici un scan Hijackthis de mon pc a ce moment:
