Power LED doesn't turn on, so does the rest of the pc

[LukeLinusFanFic]

Hi!

I just rebuilt my computer, and suddenly, when I got back home, the power LED won't turn on, and the computer doesn't start. When I hit the button, the PSU fan does one spin, and the rgb ram illuminates, but that's it. No fan spin.

 

What's the likely culprit? The motherboard? The PSU? The latter is a few years old Corsair 600w sfx model.

Thank you!

Something probably isnt seated in all the way. Check all cable connections, and reseat ram, cpu, gpu, etc.

Reseat the CMOS battery. If this fails Reseat core components. It's likely something not seated correctly if all you've done is rebuild it. 

 

A mistake I've made before is putting one of the case headers in the wrong slot. Check to make sure your power and reset headers are in the right spot. 

 

Best of luck!

You said it suddenly wasn't working.   So it was working fine, you shut it down and then it didn't start again?

 

Well reseat the GPU, check all cables, if that doesn't change things disassemble it, hook up just the motherboard

to the power outside the case and turn it on.  Should get some angry error codes, which is a sign of life.

It depends on what you define as 'rebuilt'. If that involved removing the CPU and/or cooler, then its possibly related to the CPU. PGA can be a B when it comes to even removing coolers, where sucking the CPU out of socket isn't uncommon.

 

If you didn't mess with the CPU+cooler at all, then I'd look elsewhere since that's a stone you'd want to turn over last with PGA sockets. Very easy to bend pins without really doing anything wrong.

Pull the RAM out and see if you get a RAM error on trying to boot. If yes, then plug back in one stick at a time. If no, then you have a CPU/mobo/psu issue.
