Light appears on the motherboard but doesn't send a signal to your display.
You don’t require an active CPU to power on the PC—it will remain in the same condition. The CPU debug light might flicker, or the RAM debug light could illuminate if there’s an issue. If you haven’t replaced the CPU and reinserted it, that could resolve the problem. On some motherboards, there’s a BIOS flash button; using it to update the BIOS to the latest version may help.
