You faced CPU overheating problems and attempted adjustments on the motherboard, but nothing appeared in the BIOS. You learned to connect the cooler to the CPU fan, but since your PC wasn’t built that way, you switched to fan_cpu. However, it stopped booting and displayed a bright white light on the motherboard.
Have you confirmed the CMOS is cleared? The label next to the white LED indicates the model. Which motherboard are you using?
I don’t have the CMOS battery, and it seems your motherboard might be an MSI B550 Plus Gaming model.
It appears you're dealing with a situation where only the CPU fan is now running, while the system fan was previously active. Changing the fan settings seems to have disrupted the balance, and despite reverting to the original setting, the machine still won't boot. It functioned properly for two years before this issue arose.
