If it does, go into the CMOS and write down all of the settings.
It may also be possible to fix the problem by reinitialising BIOS.
The problem could also occur due to the depletion of the CMOS battery.
For the most part, it still runs good and I've updated a few things along the way (power supply, video card).
I realize I probably need a new motherboard, but my version of Windows is OEM so I'd have to buy a new copy of that as well and right now I just don't have the funds.
There are usually three main reasons that a CMOS Checksum Bad Error occurs.
They include: The CMOS Checksum Bad Error can be fixed easily by following the listed steps carefully.
There are very few reasons for the CMOS Checksum Bad Error, hence they can be handled effectively.
A checksum is computed as an error detecting code to guard the BIOS settings stored in the CMOS memory.
CMOS Battery May Not be Functioning Properly If the user suspects that the CMOS battery is not functioning properly, he/she can easily change it.
Before changing the battery, reboot the computer to make sure that the error still exists.
Some computers warn the user and continue to boot up using settings in the CMOS, while other computers might warn the user and use the default settings in the BIOS as the correct settings and carry on with a normal boot or reboot.
