And, now the CMOS checksum error on your Windows 10 computer should have resolved. If this is the case with you, then follow the computer’s instructions to reboot your computer. Sometimes, a sudden shutdown or power cut to your computer can cause the CMOS checksum error in Windows 10 computers.Įven shutting down the computer using the power button without following the conventional shutdown procedure may also corrupt the BIOS and lead to the CMOS checksum error appear on the computer. Method 4: Fix Terminals of CMOS Battery.Method 3: Change the Old CMOS Battery to Fix the Checksum Error.

Method 2: Reset the BIOS to Fix CMOS Checksum Error – Defaults Loaded.In order to overcome from CMOS Checksum Error on the windows system, you must apply below-given troubleshooting methods.

How to Troubleshoot CMOS Checksum Error on Windows 10 System? And, this occurs the CMOS checksum error.ĭamaged Motherboard: If the motherboard of your computer is physically damaged, then it can cause this CMOS error. Sometimes, the cause of the error becomes more sinister as viruses discreetly change the checksum value. After doing this save and exit from CMOS setup.ĭead Battery: When the battery dies that is required to enable CMOS to retain BSOD settings during the computer switched off, it leads to the checksum error.Ĭorrupted or Outdated BIOS: BIOS needs to be updated in order to stay in sync with OS and hardware components. So, it is recommended to reset the CMOS and setup re-enter all values. Sudden power failure while using a computer may also affect the CMOS and lead to this error message.Īfter Updating BIOS: Sometimes when user updates system BIOS then values stored in CMOS may have been reset. Improper Shutdown of System: This is one of the common causes of getting CMOS error improper system shutdown can corrupt the BIOS values. Press F1 to continue, F2 to enter SETUP” Some Common Causes of CMOS Error This error message appears with a black screen window and some information about the error: If the BIOS values get damaged, then it makes CMOS unable to retain data, and hence you’ll get the checksum error message. This type of error message appears when the CMOS battery gets exhausted or used up. BIOS is responsible to initialize and test the hardware, such as the CPU, memory, keyboard, mouse, etc. The checksum error is linked to the BIOS ( Basic Input/Output System), it is the first program that loads when user power on the computer. Complementary Metal-Oxide Semiconductor in short CMOS is a battery-powered semiconductor chip on the motherboard, which stores all BIOS settings.
