Computer won't boot at all.

[RainbowTylernol]

And I don't mean that it doesn't post. I mean it literally does not turn on at all. The power button on my case and on the motherboard do nothing. This isn't a new build either it's a year old PC that was functioning fine yesterday.

I've been trying to find away to figure out what component is faulty but it's hard to troubleshoot when I have no extra components. The only parts I could think of that would completely prevent a system from booting at all are the PSU and motherboard. The power light on the motherboard is on so obviously SOME power is getting to the motherboard but I still haven't ruled out the PSU as the problem.

Does anyone here have any experience with this happening? I've never even heard of this being a problem

try to use a small conductive piece of metal on the pins (let it touch both of the power pins and remove) to turn it on

Exact same thing happened to me, it was a grounding issue with the monitor that I used. If you have another monitor/tv you can plug into, try that. If it don't work, it's probably still a grounding issue ... unless your PSU is broken.

It dead

Make sure the front panel connectors are in the right spots, make sure the switch on the back of your power supply is flipped to the line (on), and make sure all of the power connections in your PC (like the 24-pin, 4/8-pin EPS, etc.) are all nice and snug.

if you have mentioned that motherboard get power than try this

1try front panel pins short out to power on if its not than

2try an other monitor for example tv if it still failed to power on 

3 if you hapend to have multimeter and your psu 24pin cable is colored short green with closest black cable and check all of the pins have voltage. do it like that black testing lead to black and red to all possible pins of 24 pin and also cpu as well as molex if you have one its ok if some cables will show 0  but its necessary that psu would give 3.3v 5v and 12 v output but it also has to be powerful enough.

4 try using diffent power cable and other wall plug and repeat step 3 and finally

5 try leaving only necessary components in powered with other working psu

6 if it didnt help try swaping an other motherboard

 

7 if you found something that helped you resolve issue mark ansver as solved

So I wasn't able to get the PSU to boot by shorting the pins so I'm going under the impression that the PSU is the problem. Gonna go buy a new one today and if it works I'll mark this thread as solved.

I still don't understand how a gold rated AX series corsair power supply could die for no reason after less than a year.

Yeah it was definitely the PSU. Computer is up and running again. Hopefully no more random PSU failures in the future. I'm running an EVGA 750G2 now which has a 9.8 score on Jonny Guru
