related to BIOS and may have been reinitialized. 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. If the user cannot locate the cmos checksum error press f1 to continue pin battery, the help of a computer technician should be taken to prevent damage to the hardware or motherboard. The CMOS checksum error - defaults loaded should be solved after changing the CMOS battery. Symptoms Solutions: Symptoms When starting your PC, the following error message is displayed: CMOS wrong CMOS MEMORY size WRONG CMOS Checksum Bad CMOS checksum error defaults loaded Warning! CPU has been changed please re-enter cpu settings in the cmos setup and remember to save cmos checksum error defaults loaded before quit! You are prompted to: Press F1 to resume Press F2 to load default values and continue This is due to the fact that the CMOS, which contains data related to the BIOS, has been reinitialized and that your PC has been reset to factory settings. Solutions: Reinitializing the BIOS Before making any costly maintenance try: reinitialized the BIOS. Change BIOS battery If the problem persists this may be due to the fact that the battery powering the CMOS (when the computer is shut down it allows the CMOS to store information), is depleted. The CMOS battery is a small pin found on the motherboard; you can refer to the manual provided with your motherboard to change it or have the nearby computer technician change it for you if you don't want to risk any damage.

errors. But after a day I use it and shut it down for an hour and when I return and turn my PC again this problem comes out... I have no idea why it happened, so if anyone http://ccm.net/faq/618-cmos-checksum-error-default-loaded knows how to fix this I will gladly appreciate it... Btw.. I have some experienced on PC troubleshooting but sad to say it is my first time to encounter this problem and I have no idea how to fix it.. So please I really need your help guys.... Reports: · Posted 4 years ago Top Sarris Posts: 189 This post has been reported. Causes of CMOS Checksum Bad Error There are usually three main http://www.howtogeek.com/forum/topic/bad-bios-checksum-how-to-fix-it- reasons that a CMOS Checksum Bad Error occurs. They include: 1. CMOS Battery may not be functioning properly. The battery life may have expired. (it's probably this) 2. The user or a virus may have updated the BIOS. 3. The computer may not have been shut down properly e.g. shutting off the computer’s main power without first shutting down the computer (MS Windows requires the computer to be shut down before the power is shut off). This is from tech-faq.com Also, please don't multiple post the same question. Thanks & good luck Reports: · Posted 4 years ago Top tech27 Posts: 387 This post has been reported. First of all... Sorry for doing multiple post but I didn't meant to do that because every time I post it says "404 Not found" hmmm... so what should I do first to solve this problem ???? Reports: · Posted 4 years ago Top tech27 Posts: 387 This post has been reported. BTW.. what does CMOS means ??? Sorry I had never encounter a bios problem before..... Reports: · Posted 4 years ago Top semiretired Posts: 1214 This post has been reported. Cmos equals continuous metal oxide semiconductor. It is the small disk battery found on your motherboard. It is usually a cr2032 that can be purchased at a walmart......etc. In a laptop, it co
the CMOS Checksum Bad Error, hence they can be handled effectively. The Error Explained A checksum is computed as an error detecting code to guard the BIOS settings stored in http://www.tech-faq.com/cmos-checksum-bad-error.html the CMOS memory. The CMOS Checksum Bad Error is an error that occurs when http://www.pcguide.com/ts/x/sys/beep/phoenix/phoenixGPBC03-c.html the CMOS values turn out to be incorrect. The CMOS memory stores a specific value normally to guard the BIOS software. Each time the computer is booted, this value, which is a number is checked against the stored value in the CMOS memory. If these two values are different, it causes a CMOS Checksum error message. checksum error If these values are the same, the computer boots normally. Each computer usually deals with the CMOS Checksum Bad Error differently. 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. Usually, the strategy the computer employs is cmos checksum error stated in the error message. Causes of CMOS Checksum Bad Error There are usually three main reasons that a CMOS Checksum Bad Error occurs. They include: CMOS Battery may not be functioning properly. The battery life may have expired. The user or a virus may have updated the BIOS. The computer may not have been shut down properly e.g. shutting off the computer's main power without first shutting down the computer (MS Windows requires the computer to be shut down before the power is shut off). Solutions to CMOS Checksum Bad Error The CMOS Checksum Bad Error can be fixed easily by following the listed steps carefully. 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. If it does, go into the CMOS and write down all of the settings. If all the settings are lost, they can usually be retrieved from the computer manufacturer. Now locate the battery and remove it. Consult the computer manual or technical support to remove your battery (the battery is flat, shiny silver colored, and coin-shaped) if needed. Take down the CMOS battery’s information s

Explanation: The system has detected an error within the BIOS ROM. The read-only memory (ROM) containing the BIOS program (which is what is running when you turn on the PC and what generates this error) uses a checksum value as a double-check that the ROM code is correct. This checksum is compared against the values in the ROM each time the PC is booted and if there is a mismatch, this code is generated. Note: This error is not the same as a CMOS Checksum Error, which refers to corrupted values of the CMOS settings, the ones you set through the BIOS setup program. This error means the contents of the BIOS code itself are damaged. Diagnosis: The BIOS ROM chip on the motherboard is probably faulty. It could also be another component on the motherboard. Recommendation: Troubleshoot the motherboard. It is possible to replace just the BIOS ROM chip but often replacing the motherboard will make more sense for cost and simplicity reasons.
