I was swapping out a faulty hard drive the other day when suddenly my PC stopped powering on. This is the system:
ASRock Z390 EXTREME4 Motherboard
Corsair CX750M PSU
Gigabyte GeForce GTX 1660 6GB Graphics Card
4x16GB Corsair DDR4 Vengeance LPX Black RAM
And various hard drives
This is what I tried so far.
PSU removed and tested all pins of the power rail. All produced the correct voltage.
Power rail pins 14/15 shorted and PSU fan powered up beautifully
Removed the HDD I installed.
Removed the PWR_BTN and shorted the pins
Put the RESET switch on to the PWR_BTN pins
Removed all RAM and added one-by-one
Checked visually for blown components.
What I do have is the pulsating green LEDs on the motherboard so I know something is working.
Ideally I don't want to strip every component off the board. When I say there is no power, the PSU fan does not even start spinning. It is totally unresponsive. But I know it works.
If anyone has any ideas that would be great.
Otherwise my next steps are to remove and reset all components starting from bare minimum (CPU basically). Then I guess replace the mobo.
