Question Computer slowly shutting down after exiting BIOS ?

Mar 5, 2023
My computer randomly had both of my monitors go black and about 10 seconds later the system powered off, I turned it back on and it kept doing the same thing so I had shut it down and entered BIOS where it had no problems whatsoever staying and BIOS did not show any voltage problems or boot problems. After I had exited BIOS and trying to launch on my secondary drive it was having the same issue so I removed the cmos <battery> and let it sit out for 20 minutes before trying again to no avail.

I wiped my drives thinking maybe I had a virus or something akin to it but that didn’t work either. So far I’ve tried:

  • removing cmos <battery>
  • resetting BIOS to default
  • changing boot drive
  • launching with only 1 stick of ram in primary slot (both sticks tried)
  • launching with my M.2 SSD taken out and my HDD still in
  • launching with my HDD out and my M.2 SSD in
  • removing my gpu
  • resitting every component
  • applying fresh thermal paste
  • redoing all of the mobo wiring

Nothing thus far has worked and now I can’t even launch into the new version of windows I installed.

TLDR: Computer slowly powers off when in anything else besides windows safe mode and BIOS, almost everything tried besides using different parts.
