Mac mini keeps crashing
Can someone help diagnose why my mac mini keeps crashing?
I bought it second hand, and it had been upgraded to the latest OS El Capitan (originally it would have had OSX server). The machine looks in very good condition (physically).
It has crashed probably about 10 times in the 3 weeks I have owned it, and using it today to watch Hulu, it has crashed repeatedly. Generally, it is kept on for days at a time - not sure if this is related, although of course it is now crashing a lot today. It also seems to be the case that it crashes while video is playing, either streaming or in VLC. Usually the mac freezes completely: the video becomes still, no sound, and nothing whatsoever works (not even the ouse will move). I have to hard-restart with the power button. Alternatively, the machine sometimes just restarts and begins to boot up without a freeze-frame effect.
On this last occasion (leading me to post this), I had switched to playing a video with VLC on mute, while iTunes was playing. I have several external drives connected including a USB Hub, and also a bluetooth keyboard and a bluetooth sound system. The display is my TV via HDMI.
The panic report is below - I don't know how to interpret it. Can anyone please help?
