iMac Keeps Restarting

iMac has been very slow from day one (compared to my 3 years old MBA)

and recently keeps restarting for no reason with very similar panic report

I've run hardware diagnosis and performed a 'clean' install of Sierra but nothing helps

Can anyone let me know what I can do? Thanks

Hi rkaufmann87, thank you for your help. Everything in the EtreChek report seems fine apart from an issue related to adobe. But the restarting problem happens even before I installed adobe cc after the clean os install.

I don't seen anything obvious. Is the computer still covered by warranty, if so book an appointment and take it to your local Apple store.
