This will cause the CMOS checksum error to pop up. Let’s look at a few causes of the CMOS checksum error before suggesting a couple of fixes Out of date or corrupted BIOSĪfter a while, a PC’s BIOS will need to be updated to stay in sync with the operating system and all the hardware components you use with it.īut sometimes the cause of the error will be a lot more sinister as some viruses can discreetly change the value checksum settings and corrupt the BIOS. And different computers deal differently with the error. There are different reasons why a CMOS checksum error would occur. When the BIOS fails, starting or booting the computer becomes problematic as it cannot reconcile the BIOS settings prior to the computer switching off and on startup. So, in effect, the CMOS holds all of the BIOS’ settings. The BIOS itself is stored in the CMOS (Complementary Metal Oxide Semiconductor).

It runs independently of whatever OS you run on your PC and manages the relationship between all of the PC’s hardware elements.īut, in effect, the OS cannot operate without the BIOS as it is where all the operating system’s drivers are loaded. The BIOS is where important system data such as the time and date are verified with the CMOS.
Where the OS manages the software running on a computer, the BIOS is more a firmware that checks the computer’s RAM, processor, and it’s peripheral hardware components so the OS can load properly. The BIOS (Basic Input/Output System) is a set of settings/instructions on the CMOS chip, which you will find on a computer’s motherboard. This is an error detection mechanism is what is referred to as checksum, otherwise known as a form of redundancy check for picking errors in data. If these two values don’t match the PC may return a CMOS checksum error. When you shut down your PC the CMOS records a number that must match another that the BIOS generates when you start up the computer again. The CMOS checksum error is essentially a conflict between the CMOS and the BIOS that happens when you boot your PC.
