As soon as you switch on the power supply to your computer, the computer’s BIOS starts and along with it the CMOS program also begins. The CMOS program starts checking all hardware devices in the computer, like the processor and memory. After this it moves on to checking various other drives like CD ROM, DVD ROM, hard drive, USB drive and the floppy drive as well. Once all this is checked, it moves on to checking various files, cards and any other devices installed on the computer. The BIOS then looks out for any floppy present in the floppy drive for it to boot from. In the absence of one, it boots from the hard drive and then loads the windows registry. Any hindrance in the above process can be a cause of problems when booting up. There could be a variety of other problems which could affect your computer.

If the problem still continues, there is a serious hardware problem. Unplug all your motherboard connections and carefully connect them back properly once again, and see if it works. Your last option should be to call for an authorized computer repair agent who would help you fix this boot up problem.
