Hi there,

I'm having some bad problems here and I really need some advice, I'm pulling my hair out over this. If you have any advice please post a reply.

First, my PC was working great, then it turned off one day, I unplugged the cable and plugged it back and heard a shock it didn't sound good. My first feeling was that the PSU was broken so I ordered a new PSU anyway. I performed the paper clip on this PSU so I knew it wasn't DOA it didn't work on the motherboard though.

I came to the sound conclusion that it had blown my motherboard, so I ordered a new motherboard from the amazon (accordingly used with minor box damage) it arrived and I set up as normal (CPU & RAM) and tried to boot again but alas it would not.

So I have three options on what happened

  • The first shock actually fired not just my motherboard but the CPU and other parts also.
  • The board that arrived is DOA and that's why it won't boot
  • The CPU has been damaged but it may have also damaged this new motherboard too.,.
I note that I still get through power with the ETHERNET led on the motherboard [same on old mobo] when power is connected through the motherboard. There have never been any motherboard lights, or have I managed to POST on any of the boards yet.. All parts are validated as working on the same build also.

* I notice that on my previous motherboard there looks to be some brown almost discoloring on the CPU pin ports. Is my CPU faulty?

well im so confused.

3rd mobo, new CPU new PSU... Still got the problems 🙁

I brought a cheap 3000G AMD to place in my new b450m pro-m2 max board... I can post to some extent on this board, the EZ debug led comes on telling me there is a fault with the CPU - Yes I have reset CMOS, both on the pin and on the battery.

So I wonder,

  • My old CPU, which I thought was confirmed to be faulty as it didn't post on this new board.. Maybe it has damaged the CPU socket I dunno?
  • My new CPU is DOA
  • My new mobo is DOA.
  • I damaged my new mobo with the old CPU, yet its still powering and the ezdebug led is working..:/
  • I still have no idea if my GPU is alive or not.
  • Help.. 🙁

I really have no idea what to do, nothing I'm buying is new is working, and nothing I have is working.. please someone give me some advice..
 
It's possible your cpu is frying your motherboard. I would maybe replace the motherboard one more time and not place the old cpu in it at all. I'm not sure my issue was, I replaced the psu and cpu and my system was able to post. My old psu was able to post a different motherboard but it may have been frying my board, same goes for the cpu.
