How to confirm mobo is dead?

[nadirshakur]

So my pc died. i press the power button and nothing. i unplugged everything else, tried to reset cmos, nothing.

i tried the psu on another machine worked fine. i tried another working psu on this one and it didnt work.

The mobo's green light turns on when psu is plugged in but when i press the power button or try to jump start it nothing.

if it's a bad cpu, will the mobo still turn on and fans start turning?

any other way to try and confirm?

Even without a cpu the power supply will turn on with the power button pressed.

I would at least pull the motherboard out of the case and try it then (with anti-static material underneath, of course) - to check that nothing is being shorted out between the motherboard & the case, as sometimes that happens.

Thanks for you help. Yah I tried that, nothing. I believe it's busted. I got a new one, seems to be working fine now. My only concern now is the power supply. Even though it is working fine. The power supply makes this noise. I know it's not so unusual but i am concerned that the power supply caused the issue with the mobo. Do you know how I can test the power supply to make sure it's not killing the motherboard? Or is there really no way but to get a new power supply to stay on the safe side. I really wanna leave that as a last resort. Again appreciate the help.
