Possible broken motherboard.

[RyanLewisBull]

I originally thought that I had bought a dead PSU so I have replaced it and my computer still won’t power on which I think may be due to a faulty motherboard is there any way of testing this?

 

I when I power on my system nothing powers on whatsoever.

Are you certain you have everything plugged in correctly? Does anything at all happen when you press the power button (fans spinning, motherboard lights, the power supply turning on, etc)? 

 

If it was a broken CPU, the mobo would power on when pressing the power button, but the system wouldn't post. Same with RAM or in some cases your video card.

Usually unless something's really gone wrong with a motherboard, you can still get some power to it even if it's dead. There's a difference between all dead and mostly dead

Is this a new build? 

If so, make sure your PSU is actually switched on

 

Had this problem once with a PC I had pulled out from storage.

[RyanLewisBull]

Yeah new build and my is switched on.

I’ve tried multiple times and nothing happens, testing my psu it works so do you think it could be my cpu?

If literally nothing happens and the psu works it's not the cpu like mentioned it would atleast post if the cpu was dead so It looks like a dead mobo

Make sure you don't have a faulty case switch messing with you here.

Double-check the header connections on the board to the powerswitch and make sure it's in the correct place.

 

If you must you can try jumping/ shorting the powerswitch header pins manually to be sure it's not the switch itself causing issues.

If the board doesn't get the signal from the switch to start, the PSU itself never gets the "power on" signal from the board it needs to do so.

Yup just do that, small help

Just to be sure it's clear - With the above example the header for the powerswitch is within JFP1 and the pins themselves are pins 6 and 8. To jump/short these, you simply connect these directly together momentarily with a piece of small wire or something similar - That's it.

Be sure, however your board is layed out you know where these are but the procedure itself is the same.

Hello, I recently brought a asus prime b450m-a motherboard(new) , and today I brought 500 Watt be quiet psu(new) , i don't have CPU, because I'm buying monthly new parts, 

 

So I decided I want to test if my motherboard is working, I plugged everything in, just 24 pin and 8 pin, and it would not do a single thing want I turned in on, not even fans spinning, I don't get motherboard is brand new, I tried with a screwdriver to turn in on myself still motherboard is showing no life. 

 

Is it the cpu? , because there is no cpu motherboard decided to play dead or something, 

 

Thanks

Without a CPU and RAM it won't work period.

Try to take out engine from the car and see if it starts no way mobo will give any signs of life without cpu or ram

I’ve attempted to jump it but got nothing

There is ram, the damn fans should at last try to
