Mon ordinateur redemarre tout seul

Bonjour,

Tenez, j'ai absolument besoin d'aide, svp, mon ordi redemarre des que je l'allume. C'est un virus car à l'écran il y a un texte bizzard qui dui :
"Tiens on est déjà le 15,,
il est temps de rebooter ;)"

J'ai alos démarrer en mode sans echec et reculé de un jour, le 14.

Ca marche mais demain ca reprendra c'est sur
