I have had my PC for almost 2 years, nothing ever went mechanically wrong. After getting home, I pressed the power button, and nothing. No lights or movement of fans, or even sounds. I checked my power supply with a paper clip on the 24 pin cord and it works, the pc powered on with lights and fans. But when I plug the 24 pin into the motherboard (did about 3 times pressing as hard as I can) it never actually turned on. I tried putting a screwdriver on the 2 power switch pins to turn it on, and that didn’t work. I’m stumped and I need help from the experts.
