Da ich nicht weiß woran es liegt schreibe ich das mal in "Sonstiges".
Ich fahre den Rechner hoch, sehe noch ca. 20 Sekunden lang den Start-Screen "Windows" (höre wie die Daten von der Festplatte geladen werden) und dann schaltet sich der Rechner einfach aus.
Nachdem ich einen Wiederherstellungspunkt vom Vortag aktiviert habe ist das Problem vorerst gelöst.
Hier habe ich mal eine Logfile von Hijackthis
