There are too many reasons to clear cmos. the simple reason is that, sometime we changed the bios settings and wo dont know wht we have done. many motherboards never go to boot cd room, so we have to clear cmos and set it as defalut settings. when we update its bios.

When our pc is out of order and we dont know wht to do.sometime we buy a pc and we try use printer and we dont have printer option, so we go to setup and make it as dafault by clearing cmos. i means so many time our pc ports are in good working position but in bios setup , they are disabled. in simple words when we clear cmos, then we got the geniune factory settings again.
