Has it just died?

[DJfern94]

Hi all, 

 

I've been using my PC as my daily driver solid for the last 6 years or so. Today I have come back from work to try and turn it on. 

 

It seems to be stuck in a power cycle, I press the on button and then every second or so it turns itself on, fan spins, turns itself off. No error code as the mobo display shows usual booting code 00.

 

I've not got a lot of equipment to test at home so I've been trying to go step by step. 

 

Bridged the 4/5 pins on the psu to test that, when bridged the power supply starts up fine. 

Taken the ram out one by one and placed them back in, no luck. 

Reseated cpu, no luck. 

Unplugged everything and tried again, no luck. 

Taken gpu out and tried again, no luck. 

 

Is it a case that the motherboard or cpu has died? Or am I missing something?

 

Thanks

Disconnect everything except the mobo from the PSU, including all drives, then also take the GPU, all storage, etc. out and try booting up without any GPU in and only one RAM-stick. If it's still doing the power-cycling, it's probably the mobo.

Thanks, yeah done all that so it must be the mobo.

Make sure the power button is not stuck in the on position.  Had that happen to one of my systems, all of a sudden it started looping.  It would turn on then shut down, then turn on...continuously.  Found that the power button on the case got stuck in the on position on the case.

Thanks, yeah I've taken the board out and tried booting just on the board itself, still no luck. 

 

Thamks though
