Battery Failing at some point in time.

On an older PC, it is normal for the CMOS battery to fail at some point in time. They usually last for lots of years. On a brand new motherboard, this sort of issue is usually a sign of a defect. Often, a dying battery will first manifest itself intermittently. Sometimes, I boot with no issue.

At other times, I see an error indicating that the technique doesn't match the configuration or the Date & Time settings on your computer are wrong. When the battery fails entirely, these errors will either come up every time I reboot, or my BIOS may document a mistake number with a message stating that the battery is dead. Give me the solution?

The facts you have stated are all correct and CMOS battery failure is indeed a sign of Motherboard of chipset failure or defect. It will be very annoying to face the unexpected failures with CMOS battery failure. Lot of times the System date and time is reset to manufactured time due to these failures and sometime your System may come across difficulties in recognizing hardware components connected to PC.
 
This will also resets your customary CMOS settings and other monitoring services. The easiest solution is to replace the CMOS battery with new one same as before (5V battery). Take off the CMOS clear jumpers an clear the bios for any ROM corruption before fixing the new battery. If the Motherboard is under warranty period (Normally 3 Years) visit your dealer and replace the motherboard.
