Motherboard has light, but no display

[fatestaynight1315]

Hi guys,

My pc suddenly died on me for no apparent reasons.

At first I thought my ram were dead but I have 2 8gb ram sticks, one of which is fairly new.

Googled around and many post suggested that it might be a bad PSU,
As the motherboards was showing no sign of life,
So I changed PSU and the motherboard was still dead with no post or display. I read some more and it suggested if not the PSU then the motherboard was bad

So I changed motherboard too.

I tried with each ram stick I known once still nothing.

The fan spins for one sec then die.

I reapplied thermal paste and check my cpu too.

Still not working, I don't really know what to do anymore. Suggestions?

EDIT: peripherals not working either
When short to power on, CPU fan spins then stops

Ryzen 1500x
Gtx 1060 3gb
Corsair vengeance 8gbx2
Asus prime b350-e (new board)
PSU thermal take light power 650w

Are the front I/O cables plugged into the motherboard properly?

Yes , but pc still didn't power on

I removed them and try to short the pc on instead,
CPU fan spins for a sec then nothing. Light on motherboard still on
