It sounds like a serious issue, but there are several steps you can take to diagnose and potentially fix your PC. Here's a structured approach to troubleshoot the problem:

Initial Checks​

1. Power Supply:
   • Ensure the power supply switch is turned on.
   • Double-check all power cables to make sure they are securely connected (both to the motherboard and components).
   • Try a different power outlet to rule out any issues with the current one.
2. CMOS Battery:
   • Remove the CMOS battery from the motherboard, wait for a few minutes, and then reinsert it. This can reset the BIOS settings and sometimes resolve power issues.
3. Basic Connections:
   • Disconnect all peripherals (mouse, keyboard, external drives, etc.).
   • Remove and reinsert the RAM sticks. Try using just one stick at a time if you have multiple.
   • Ensure the GPU is seated correctly if you have one.

Deep-Dive Diagnosis​

1. Motherboard Jump Start:
   • You've already tried jumping the power switch pins, but make sure you did it correctly. Refer to your motherboard manual to locate the correct pins.
2. Check for Shorts:
   • Ensure that there are no loose screws or components causing a short on the motherboard.
   • Check for any visible signs of damage, burn marks, or swollen capacitors on the motherboard.
3. Test with Minimum Configuration:
   • Disconnect everything except the CPU, one stick of RAM, and the power supply. Try to power on the system in this minimal configuration.
4. Speaker/Beep Codes:
   • If your motherboard has a speaker or debug LEDs, use them to identify beep codes or error messages.

Advanced Troubleshooting​

1. Try Different Components:
   • If possible, try a different power supply that you know works.
   • Test the RAM, CPU, and GPU in another working system to ensure they are functional.
2. Check for BIOS Corruption:
   • Some motherboards have dual BIOS or BIOS recovery features. Consult your motherboard manual for instructions on recovering a corrupted BIOS.
3. Inspect Power Delivery:
   • Check the 24-pin ATX and 8-pin CPU power connectors. Ensure they are providing the correct voltages.

If Nothing Works​

If none of these steps resolve the issue, it may be that your motherboard or another critical component has failed. Just consult a computer specialist or technician
