PC suddenly not turning on.

[klnstpr]

Hi, totally out of the blue my pc stopped turning on today. I literally turned it off a couple hours back and now it doesn’t work. My first assumption was that the PSU is dead, as it served me well for quite some time now. However, after removing the GPU, it starts fine (leds and fans turn on, they don’t with the gpu in). So my question is: my gpu is 100% dead? Or could it be that the PSU is faulty and doesn’t have enough power to start with the gpu inside.

 

Specs: GTX 1080 msi armor oc

Mobo: msi mag b550 tomahawk

CPU: r5 5600x

Ram: 2x16gb crucial ballistix (I don’t remember the clock speed)

Psu: some chieftec 600w one (popular in Poland, presumably a decent brand) Update: chieftec gps-700A8, 700w

 

Note: Every cable but the power cord was unplugged when it run without the gpu.

Another note: when powering on with the GPU inside, it only reacts to the power button once. What i mean is, after the first press mobo lights up for a split second (the ez-debug cpu led lights up red too). Then i need to unplug it from power, wait a few seconds, and then plug it in again to replicate the behaviour.

 

Update: PSU arrived (be quiet pure power 11fm 750w). PC still does not want to power on with the GPU in (but without the funky shit i described earlier). GPU-out it powers on fine. I figure the GPU is dead.

note: also tried connecting it to a different pcie slot but with no success.

Test the GPU in another PC and you'll have your answer.
Does sound like the PSU might be giving up though, hard to say.

The GPU isn't necessarily dead. But it sounds like somethings gone wrong with the PSU.

Did a power surge happen. Lighting strike in the area or ground or purely it just randomly died with no suspected reasoning.

 

Take the GPU out, place it in an new one and try seeing what happens.

Let's focus on this part. Does toggling the power switch on he back of the PSU achieve the same result as removing the wall cable and  waiting a few seconds?

 

What you're describing is typical of a PSU failure, where some protection, overvoltage or overcurrent or etc, is being triggered on the PSU

 

It's possible that the GPU is faulty and is triggering the fault, but you'd need to try a different PSU or GPU to confirm. My first guess is the PSU is choking on the GPU during POST

^this.

 

It's definitely a hardware fault. But could even be just a faulty PSU cable, I'm assuming though that the chieftec PSU isn't modular?  but hopefully it has another GPU cable you can try?

If no luck there, i'd carry on with what others mentioned above.

I have to physically unplug the psu from the wall to trigger this.

Not modular, unfortunately only one gpu cable.

I am not 100% certain, since I wasn't home during that time. Power surges do happen sometimes where I live. I have the only pc in the house so no way of trying in other machine.

Thanks for all the answers. Bought a new PSU, should arrive on friday. I will post an update whether that fixed it.

Alright all good.

I opened it up (photos below). I imagine that the discolouration is due to overheating? Can I save it somehow?
