[iMac] iMac 21.5-inch Late 2012 stürzt plötzlich ab

[n3acal]

Hallo zusammen

Seit ein paar Tagen habe ich ein Problem mit meinem 21.5-inch iMac von 2012 (läuft mit El Cap 10.11.5). Plötzlich crashen einige Apps (bspw. Safari) und dann reagiert der Mac überhaupt nicht mehr. Eine signifikante Systematik konnte ich bis jetzt nicht feststellen, häufig war aber ein YouTube-Video involviert in den Crash. Ich habe keine Ahnung, wie ich das Problem anpacken soll. Gibt es Vorschläge?

Ein aktueller EtreCheck-Log findet ihr anbei.
