U hv to change the CMOS battery.
Look in ur motherboard and U'll find a small coin size battery, replace it with a new one.

u can reset the cmos by resetting the jumper

see your mobo manual its there on how to do this

coz this varies from mobo to mobo
for mine it was rj2314 jumper

1. As far as you're concerned, BIOS and CMOS are the same thing. BIOS (Basic Input Output System) speaks of the function whereas the term CMOS (Complementary Metal Oxide Semiconductor) comes from the technology used in making the BIOS chip or IC (Integrated Circuit).

CMOS technology is used to make many different types of electronic ICs, one of which is the BIOS chip on a motherboard. It's like saying 'house' or 'home' - your house may or may not be your home.

2. As already pointed out by others, your problem is most likely to be a weak CMOS battery. When your computer is turned off, the CMOS chip draws a tiny amount of current from the battery to retain your settings. If the battery is too weak, all your settings will be lost when the computer is turned off.

Practically all motherboards use a CR2032 lithium battery. When going to buy a new one, you can ask for a CR2032 battery or simply a CMOS battery or you can remove the old one and show it at the shop.
