Bluescreen nur auf Facebook

Hallo,
mein Computer macht zw einen blauen Bildschirm mit weißer Schrift und schaltet nach kurzer Zeit ab. Ich habe das Problem lange beobachtet, alle Treiber im Gerätemanager aktualisiert, ohne Erfolg. Der Fehler tritt nur auf wenn ich auf Facebook bin, zw wenn ich Videos ansehen, manchmal reicht es nur auf Fb zu sein. Auf allen anderen Portalen (Youtube usw) kein Fehler. Ich habe es mit WhoCrashed v5.02 analysiert, siehe unten.
