Desktop nach Start weg!

Hey,
ich habe schon viel gelesen, aber es war nie das richtige dabei.

Habe seit 2h ein Problem. Mitten im Betrieb ist der Desktop (Taskleiste, Icons) verschwunden und es hat scih die Biblothek geöffnet.
Nun war also nurnoch das Hintergrundbild und die Bibliothek zu sehen.

Habe den Rechner dann neu gestartet.

Am anfang ist die Taskleiste und auch die Icons zu sehen, doch wenn der Rechner fertig gestartet ist (25sek zum Desktop aufbau), verschwindet alles und es öffnet sich wieder die Bibliothek.
Auch der Taskmanager geht nicht.
Wenn man ihn dann wieder herunterfährt, kann man kurz wieder alles sehen (1sek) und dann ist der Rechner halt aus.

Bin jetzt im Abgesicherten Modus mit Netzwerktreibern!
Ein Virenscan mit Avast hat nichts ergeben.

Hier mal ein Logfile von HijackThis:

Ich hoffe ihr könnt mir helfen.

 

Was hast du zuvor am PC gemacht? Etwas installiert?

 

Ne, hatte nichts installiert. Das Problem hatte ich vor 2-3 Monaten schon mal und irgendwann war es weg.
Habe im abgesicherten Modus noch mit CCcleaner mal alles gereinigt.

Am nächsten Tag ging alles wieder normal.
Also momentan funzt es wieder.
Ka was es war.
