I tried my old psu, but still the same.Must be faulty PSU. Faced similar issues in the past. Try with any spare PSU before it permanently damage any other component.
It's wierd, the pc started with my current psu, rebooted when the Mobo logo screen came up and then was fine.
I shut it down and started up again for the same to happen. I ran a few apps even started a game and it was fine.
Restarted again for it to boot properly only for it to get stuck on the cpu debug light
Connected my old cpu and disconnected
everything but the cpu and tried, still won't post
Have called the electrician to check.Ensure the wall socket or line isnt faulty as well as most of times users end up changing their rigs but forget to check electricity issues in their house..
Also if using ups/inverter check them too.
I'm at the end of my rope now. For the life of me I can't figure it out
