Your CMOS battery has had it and needs replaced.

You need to change, or have changed, the battery on the motherboard which holds the CMOS in memory. When the battery is dead or removed the settings are lost and the computer has to start over every time you turn it on.
Depending on your model this can be a simple fix. If you are not familiar with removing the cover to get to the battery, take it to a qualified technician.

There is lithuim battery on the motherboard, which supplies power to the bios and cmos, these two chips remember the time & date, and the setting of the computer/laptops.
they usually have along life two to three years, it must have finished so u must buy a new one.

Sounds like the CMOS battery needs replacing.

Simply take it to a shop and have them check it out. They will need to replace the CMOS battery and tht should fix everything for you.
