Hi
I'm new to this forum and need some help solving an issue with a new PC that I'm building.
After I assembled all of the components the computer powers up for less than a second and then turns off. I've plugged the power supply into another computer and it's working there. I've disconnected all of peripherals from the motherboard and the problem still occurrs. Does this mean I've got a defective motherboard that's causing the power supply to shut itself off.
Any troubleshooting advice?
