My PC doesn't boot , the led screen shows 00 and the monitor won't show output as well.

Last time of use the screen froze and after power cycle the problem occurred.

I have CPU AMD FX 8320 , 8gb ram and amd radeon HD7970 GHZ edition.

I've tried clearing CMOS , no change .

The CPU is not overclocked.

Any tips what can i do to troubleshoot the problem? Thanks

EDIT: The power button on front panel and the one on the motherboard can't turn on the pc , only way i can turn it on is via the power switch on the PSU after several tries.

EDIT 2: Found out the issue , the PSU cable leading to the CPU is fried on both connections, How in hell this can happen? And what can i do?

Sounds like there may have been damage to the motherboard if the soft poweron is not working. All the soft power on does is connect the green wire of the 24 pin to ground via software switching. Using the paper clip by passes it. If you feel the PSU is damaged then Seasonic has a good RMA program. You might tell them about the wire being melted and that because of this you are not sure about the PSU and would like to either send it back for testing or RMA.

I would test it in another system if you have one or find another PSU you can use to test your motherboard. I have a feeling that there might still be a problem beyond your PSU.

That sounds like a RAM problem. What RAM modules are you using Make, Model and Speed? I would try removing all RAM except one module.

[Edit]
Never mind...

" EDIT 2: Found out the issue , the PSU cable leading to the CPU is fried on both connections, How in hell this can happen? And what can i do?"

Your cables can burn if you either connected them backwards (which is hard because the connector is keyed to prevent this) or you installed a new higher wattage motherboard that the PSU does not support (but that usually takes time to appear) or your motherboard has a short in it.

My guess is the latter. Remove your motherboard from the case to see if it was shorting against the case. You might have a missing standoff or a bump in the motherboard tray that is causing the case to short against the motherboard.

I believe that PSU is modular where the cables can be removed from it, right? Did you double check that the CPU cable is plugged into the connector labeled CPU on the power supply?

Upper right hand corner. I think the cables are keyed so that you can't mess this up unless you use cables from another modular power supply that can be keyed different. The nice thing about that power supply is you can get replacement cables.

Still double check your board is not shorting against the case.

Hi , Thanks for the replies and the feedback. Actually yes i found a spare cable in the PSU box , the one which connects to the upper right corner. And the one i was using before was the on the lower left corner socket.

So after i dismantled the motherboard from the case and connected all the cables on the standalone motherboard without the case, with the new cable as well.

After the PC started, the LED on the motherboard actually showed some numbers now and signs of life , before was 00. And the PC booted normally.

So now the question , is the PSU faulty or you are right and the motherboard actually short circuited against the case (i was actually missing some metal pins 2 or 3 ).

I would have been convinced the motherboard short-circuited , except that i actually found that the PSU is faulty after following the jump start guide from Seasonic. The problem is that the PSU didn't power on immediately (that is with a paperclip short circuit, disconnected from the motherboard and connected to a wall socket). But was the same as how i was powering up my PC until now for the last year, and that is the power button on the motherboard doesn't work but i have to power-cycle the PSU from its physical switch on the backside several times and then the PC starts . Thats how i powered it on now as well , that didn't change.

So now after all that i ask you, do you think the PSU fried the cable after power cycling it for so long against his will and it's actually faulty and i have to replace it?.
Or actually the motherboard short circuited and that fried the CPU cable? But then again that doesn't explain why the PSU doesnt start from the power button. Thank you.
