Here's how to Fix Red CPU light on Motherboard with no display issue.

A red CPU light on the motherboard with no display on your Windows computer typically indicates a CPU-related failure. Here are some things you can try:

- Reseat the CPU - Remove it completely and reinsert it into the CPU socket. Make sure no pins are bent and the notch aligns properly.

- Verify CPU fan header connected - Make sure the CPU fan cable is plugged into the correct header on the motherboard.

- Clear CMOS - Reset BIOS by removing the CMOS battery for a few minutes or shorting the CLR_CMOS jumper pins.

- Test with known good CPU - Replace the CPU with a confirmed working one to rule out a faulty CPU.

- Update BIOS - An outdated BIOS can cause compatibility issues. Flash latest BIOS version.

- Check CPU for damage - Closely inspect the CPU pads and underside for any scratches or damage. Replace if needed.

- Remove all components except CPU and RAM - See if it posts with just the CPU and one RAM stick to isolate the issue.

- Test power supply rails - Use a multimeter to confirm the CPU power rail(s) are delivering stable voltage.

If the red CPU light persists, the CPU itself has likely failed or is not compatible and needs replacing.
