Cards turn off after shot period of mining

I made a post here: https://www.reddit.com/r/gpumining/comments/jfd3jw/need_help_as_system_reboots_after_error_messages/?utm_medium=android_app&utm_source=share

And I got lots of responses but I still couldn’t manage to fix the problem. I have 8 AMD 5700 and as said in the title they turn of one by each other after a few minutes. I would greatly appreciate any help! Sorry for posting this again but there are no new people accessing the old thread.
