CPU not powering up

CPU not powering up

Tried disconnecting the PSU and checked it by shorting green and black wires. It is working. However, when I connect it back to the motherboard and try to switch on the computer, all I hear is a faint click sound. The light at the back of the PSU turns off as well. Of course, the CPU does not power on. What might be the reason?

It could be a failing power supply, but it could also be a bad mother board. Most modern power supplies shut down when there is a short. The only way to know for sure is to get another power supply or another mother board.

"It may be that your motherboard is broken. If it is making beep sound and the power LED is on there is a chance that your motherboard is fine.

Check if your power supply is working by attaching it to another motherboard. If the power supply is working than check the RAM is working by putting it in a friends PC.

In most cases, the CPU is not faulty and the fault is elsewhere."
