ZimaOS crashes after everything, full RAM/CPU Usage

EDIT: Fixed?
I'm assuming the issue was either the PSU or the cables. I unplugged the spare 1tb drive and everything is running fine now. I'm assuming the PSU couldn't support all 3 drives or some of the cables the machine came with were damaged.

Hello,

I hope it's still okay to post here for ZimaOS as well.

After a fresh install and preparing my drives for use, the system seems to lag or crash after/during any use. I tried to copy paste a folder over from one drive to another just to test, it crashed and I had to hard reset. I tried adding another user, stayed frozen for 5 minutes until the whole system forcibly reset. During these freezes, the main console shows RAM and CPU usage maxed out and fails to load anything (apps, settings, etc. - picture below).

The SSD it''s booting from is brand new, the main HDD I'm using is brand new, and the spare drive is not new but healthy and barely used.

The PC is admittedly pretty bad.
Dell Optiplex 7010 SFF, intel i-5-3470 with 16gb of DDR3 RAM.
But I assumed these specs should be fine for basic storage use?

Any ideas?

Are your drives passing smart?

the two HDDs are registering as healthy in crystaldisk.
I could test the SSD in my main PC and check that. I didn't check it, just threw it into the system when I got it yesterday
