Motherboard Dead - Totally not powering on

[Hiro Hamada]

I checked the PSU(Corsair TX750M) and it is working fine. My pc doesn't power on after a power outage in my area. My motherboard is MSI Z370A - Pro with Intel i7 8700K. I disconnected the motherboard and only plugged in my PSU, CPU and RAM and tried to power it on. No sign of anything 

 

My question here is can a motherboard power on(the mystic light LED in the motherboard itself) even though the cpu is removed from the socket? If so, it did not even power on any LED light as shown in the picture(that white light)

Reseat CPU if you haven't yet, was my issue with a "dead" mobo case.

Did you unplug your PSU from the wall for at least 30 seconds and then plug it back in? May have a built in surge protection

[MR H.]

Did you try to reset your motherboard?

Who knows, give it a shot

Or find a friend and start swapping components(pretty risky)

Pull the CMOS battery for 5 minutes and then reinstall it.

Just to make sure that isn't the issue.

I have removed cpu and inserted back. Powered the mobo on. No sign of anything

Oh yeah it might have. But even if so, the LED strip build in the mobo should light up even for a second when powered on. It didn't

Warranty has already been expired. So I'm shipping the mobo to a service center so they can fix the problem. I'm afraid if the cpu is damaged and that could be the reason why the mobo isn't turning on

Yes. Tried this. Didn't work

If the power supply has a flipped protector that needs reset, it won't send any power. It might be worth a try if you haven;t tried already.

You can try to get a PSU from a friend and try it

I tested all the 24pin in the PSU with a multimeter. It's working fine. All I need to know is - Can a motherboard turn on/light up/beep even for a second if the cpu is removed from the socket?

My psu is fine. I tried the paperclip experiment to see if the fan turns on in the psu. And yes it did

Can try.. It'll go into post and fail on the cpu

Wait. What is post???

[mr fobs]

power-on self-test Its a term used to signify what happens before the computer gets to the bios splash screen.

That doesn't mean that it's delivering the voltage that a motherboard need

It means that it's able to start, but maybe it isn't delivering voltaje on any of the needed volts

You will need something like this or another PSU to check it

I checked each of the 24pin with the multimeter. Each pin is delivering the exact volt as specified in the Corsair box. Thanks. This equipment looks fancy tho

What it means is that the most part of the motherboards have a tiny "operating system" that try to check itself and check the components

 

If you remove the CPU, maybe will try to boot and beep on the speaker()if its connected)

 

That should confirm that there is no short circuit on the CPU

Ok yeah the motherboard doesn't light up even if cpu is removed so it's definitely a sign on a dead mobo. I just watched videos of mobos turning on without RAM or cpu. I guess mine is totally dead

[mr fobs]

If no lights or life or anything and psu is fine, then yea sounds dead.

No sign of anything when powered on after i removed the cpu

If it doesn't do anything i guess you will have to burry it..

Now my main concern is well this dead mobo damage the costly cpu if it's powered on again at the service center?

[MR H.]

Usually and with the Mobo prices i would think on buying a new one instead of repairing the old one...
