Loud pop and pc won't start

r44b · 3 Jan 2015 at 16:28

I was about 15 minutes into playing some Total War Rome 2 on my barely 3 week old pc and there was an almighty pop and the pc shut down and will not restart. I imagine it is the power supply but there are no dodgy smells or smoke. I haven't had anything like this happen before.

How should I handle this? As I am terrified it's just gone and fried a couple grands worth of components! Should I even attempt to power back up or might I risk damaging things?

The specs are:

PSU: Corsair AX1200i
CPU: Intel 5930k
CPU Cooler: Corsair Hydro H110
Motherboard: Asus X99-E WS
RAM: DDR4 16GB Corsair dominator platinum 2666
GPU: Galaxy GeForce GTX970 OC silent infinity black edition

The machine was behaving perfectly fine prior to it happening, I have yet to overclock it so everything was still running stock specs.

Got access to another PSU?

pull the PSU cables out and short the 24pins green wire to a black wire which will start it up.

But im going to have a guess that all the wires are black on that PSU for "looks"?

Don't powerup again with that PSU.

Thanks for the advice, unfortunately I don't have a spare and yes the wires are all black

Google for an image of the pin out on the 24pin ATX connector.

axi series have a self test button, so you can unplug all the cabling and try that. IIRC its just to the side of the link sockets. Pop doesn't sound good though. Best of luck.

completely forgot about that handy feature.

As expected, it is completely dead, off to support I go

I just really hope it hasn't damaged any other components.

Unlucky sir

My Cousins had one go in a very similar way, tripped the circuit breaker too. They then had a few goes at switching it back on (it went "pop" on every occasion) before they called me. New PSU and it was fine - no damage to any of the other components. Unless it surged, which is unlikely, you should be fine hopefully.

I had a PSU die last year. It also popped and the PC went off. Nothing was broken and I'm still using the PC. It should be fine.

remember.....once you pop you just can't stop !!! :eek:

hope you get it sorted,if the psu is any good it will have protected the other components

Are you sure that the sound came from the PC and not your speakers, if you have any?

Maybe you had a power surge which messed with your speakers suddenly causing them to make a pop noise (mine do this when I power them down).

The surge could have also killed your PSU which would explain the PC not powering on.

Wouldn't surge protection leads protect you from that?
