2017 iMac restarting

I just got my second 2017 iMac the first one was sent back for a restarting problem. And now this one has started to freeze and then restart. just wondering if anyone else is having this problem.

dont have the issue. sounds liek a software issue if you have 2 machines with the same unusual problem. does it happen with a clean install?

my first one was returned then I ordered a new one they did have me try a clean install before apple had me return it.
I have not tried the clean install on the new one yet but I will tonight. thanks for the advice

Could be older software transferred over if you used Migration Assistant.

Did you put in any third-party memory?

Because of the problems with the first iMac I just set it up as a new computer. All my files are on an external hard drive but I haven't connected it yet.

No have not put any third party memory in this one.
But the one I returned I did put some memory in that one but once it started to restart I removed the memory and sent the memory back but the problem continued.
With this computer it has froze and restarted 2 times so far 1 when I first opened photos and the other when I opened Safari.
The first Imac would restart sometime when it was asleep.

I've had a rMBP have consistent restart issues due to a USB device, but my second guess, if it's not a bad run of Apple products, is that however the power is being supplied isn't correct (enough, or voltage isn't consistent, bad outlet, etc). The USB issues I've had have been power draw issues. Maybe the iMac is drawing more power than previous computers. Uncommon computer problem, but worth trying another outlet.

Thanks for your response. I think I could have found the problem. Yesterday I unplugged a blu-ray burner that I bought from OWC and it has not restarted once. so I'm thinking it may be the problem. I did read that you should unplug every thing and see if it continues to restart so that's what I did.
I can't imagine that i could have 2 new computers with the same problem so it must be something on my end.
I talked to OWC they said to plug it back in and if it continues to restart they would set up a RMA to check the blu-ray burner.
