[10.10 Yosemite] MBA Mid 2012 stürzt seit zwei Wochen ständig ab

[ictus]

Liebe Mit-Apple-Begeisterte!

Mein MBA Mid 2012 hat mir drei Jahre gute Dienste geleistet. Seit zwei Wochen stürzt es allerdings ständig ab. Ein SMC-Reset hat nichts gebracht und ein Arbeiten ist kaum noch möglich (ich habe mittlerweile von jedem Dokument dutzende wiederhergestellte Dateien...). Weiß jemand Hilfe?

Ist Office aktuell. Word macht Probleme.
Sicherer systemstart schon mal versucht um zu sehen ob es besser ist?

Vielen Dank für die Hilfe! Den sicheren Systemstart (kannte ich bis dato nicht) versuche ich jetzt gleich mal.
