How to FIX | CMOS Checksum Error | Tutorial | PC Repair 

If you have perform the steps and still the meesage is shown then it's time to conclude that there is a problem with the mobo. I have a mobo with this kind of error each time I replace a cmos battery it will work but after 3-5 days it goes back to the same message again.

@@wreckitreal7170 Tnx for the Video bro, Now the msg is gone after following steps in the video. Also tnx for replying❤️❤️

mostly po yes. if error parin then kadalasan mobo na ang may problem.

Hindi po. hindi affected ang hard drive kahit palitan ng bagong cmos ang motherboard.

After pressing power button press immediately f2 or delete button multiple times until bios settings appears. It works most of the time.

​@wreckitreal Esc Button Not delete 😉 Thanks for the Video bro

@@masonicpride7072 yeah some motherboards is also ESC button.

then Ram is broken which also causes bios checksum error if you have more then one ram chip you can test unplug and shuffle ram modules together with new CR2032 bios battery.. if nothing helps board went bang!
