@drifting basin Power supply failure?

drifting basin Sep 20, 2025, 11:45 PM

#

No

#

The powersupply works

#

It's the same one I've been using

#

I think it's a dead cpu lol

#

This cpu just has never worked ....YET

thin cave Sep 20, 2025, 11:46 PM

#

Was it working before? Or is this trying to revive something else?

drifting basin Sep 20, 2025, 11:47 PM

#

I alr had a pc build but I was replacing parts

#

And well everything works but the cpu

You could try unplugging literally everything and trying to boot with just the motherboard, CPU and RAM

drifting basin Sep 20, 2025, 11:47 PM

#

I did nothing happened

#

Lol

#

CPU upgrade? As in, BIOS not liking it, maybe?

drifting basin Sep 20, 2025, 11:48 PM

#

Idk

#

I went from x99 to am4...

thin cave Sep 20, 2025, 11:48 PM

#

Hmm...

drifting basin Sep 20, 2025, 11:48 PM

#

So unless I had another cpu I can't do anything

thin cave Sep 20, 2025, 11:48 PM

#

How powerful is your PSU...

drifting basin Sep 20, 2025, 11:49 PM

#

550w

thin cave Sep 20, 2025, 11:49 PM

#

And just to be sure, you hooked up the CPU power with the CPU cable and not a PCIe cable

drifting basin Sep 20, 2025, 11:49 PM

#

It's also not a powerful cpu AT ALL

#

It's a 1st gen rzyen

thin cave Sep 20, 2025, 11:49 PM

#

Maybe something is shorting out, I dunno, I'm running out of straws to pull

drifting basin Sep 20, 2025, 11:49 PM

#

Well

#

I do have the cpu cable plugged in

#

The ram turns on

#

But

#

No fins or any gpu lights
