I just recently bought a new pc and i noticed that there is no cmos jumper my motherboard is ASUS AMD B450 someone tell me if i have it but i just dont find it and sorry for my bad english
Motherboards usually have either a clear CMOS button or a jumper. In any event, removing the CMOS battery for a minute or two will also clear the CMOS.
The clear CMOS button or a jumper will be detailed in the motherboard manual.
