The motherboard has a CMOS battery. The CMOS battery controls the system configuration and start programs. If the CMOS battery is out of power, it will affect the motherboard BIOS data. And your BIOS setting will go wrong. Then your pc doesn't turn on.

In general, CMOS can be used for a long time. You can spend a few dollars on the shopping website.
