Startup Chime Looping on boot, recovery not working
I am repairing my A1418 iMac late 2015 EMC 2833, and I can’t seem to find a proper solution to the problem. On boot, one of two things happen. Either it goes straight to looping the startup chime and the fan speed goes crazy. There is also no display output. The other thing that happens is sometimes, I can get to internet recovery mode as the hard drive has been wiped, but after between 5 seconds to 10 minutes, the computer freezes and goes back to looping the startup chime with no display output. I have tried SMC reset, PRAM Reset and NVRAM Reset. Attached is a video of what happens when it boot loops. The video also shows the diagnostic lights. In fact, the fan was so loud, it is hard to hear the startup chime.
EDIT -
I ended up using a Linux USB to go in and erase everything. Now, doing an internet recovery it has been 30 minutes, and it is restoring itself. It has yet to freeze up, knock on wood.

What is the history of this system? What did you do to the system?

I’m not actually sure. I got it free as someone was throwing it out
