Cmos Checksum Error Gigabyte Motherboard
Share Purple18 14 January 2012 08:59:32 Hello, I've bought a gaming computer online that contains main bios checksum error gigabyte motherboard a GA-970A-D3 Gigabyte motherboard. I've been using it for about 2-3 months now without any problems. I did not update my BIOS or

anything because I expected the website I bought this computer from (cyberpowerpc) to have already taken care of that. One night I shut off my computer, and the next day I turn on my computer, it boots main bios checksum error retrieving recovery source from hpa as it normally would: the computer gives one beep, and I receive the logo message. But then, I receive this message: Quote:Warning: MAIN BIOS CHECKSUM ERROR! Retrieving recovery source from HPA..HPA BIOS not available!! Retreiving recovery source from Back BIOS.... Done! Writing BIOS Image..... _____K OK The part where I added the "_______" contains a number that increases all the way to 4080K, and then the computer reboots and completely restarts this process. Some main bios checksum error gigabyte loop extra information: 1)My PSU is not the issue as it's a 700W Corsair Brand PSU. My PC originally came with a 700W PSU with a very bad brand (XtremeGear), so I replaced it with the Corsair the minute I got it (Which was 2-3 months ago XD) 2)I've already cleared my CMOS by both using the jumper, and removing the battery for 30 seconds with no success. 3)I don't believe it is a wiring issue because it worked untouched for the 2-3 months that I have been using it. 4)The cursor is under "OK" when I am given this error message, but pressing ENTER or any other keys will not do anything. 5)I am still able to enter the BIOS menu from the logo screen. 6) I have Q-Flashed the BIOS from F6 to F7 and the problem still persists. The only thing that I haven't tried is replacing the battery, which I am planning on going over to CVS and buying one tomorrow, but I really don't think the battery is the issue since I've only had this computer for 2-3 months. I've tried to be as detailed as I can in order for someone on the forums to help me, but if there is any other information that you need, please reply and let me know. I have spending a
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 the CMOS

memory. The CMOS Checksum Bad Error is an error that occurs when the CMOS values gigabyte ga g31m es2l warning main bios checksum error turn out to be incorrect. The CMOS memory stores a specific value normally to guard the BIOS software. Each time the computer
Gigabyte G31 Bios Checksum Error
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. If these values are the same, http://www.tomshardware.com/forum/304846-30-gigabyte-motherboard-issue-main-bios-checksum-error 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 stated in the error message. Causes of CMOS http://www.tech-faq.com/cmos-checksum-bad-error.html 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 such as volt, size, etc. Replace the old battery with a new one and reenter the CMOS
2014 by Alex Barbos A BIOS checksum error is one of the most common errors you can encounter when you build your own computer, perform a hardware upgrade or attempt to bring back to life a computer that hasn’t been used for a long time. https://blog.udemy.com/bios-checksum-error/ If it sounds like a scenario that’s not very likely to happen to you, think again, http://www.techspot.com/community/topics/cmos-checksum-error-continues-after-battery-replacement.4577/ as computers became so un-complicated that you don’t need to be working at NASA to know how to upgrade or even build one yourself; in fact, learning how to build your own computer is as simple as taking this online course, so the possibility of coming across a BIOS checksum error one day is higher than you think. The error indicates that checksum error the BIOS is incorrectly configured or corrupted, preventing the computer from booting normally; unlike operating system errors or software errors that occur after your computer is up and running, a BIOS checksum error will render it inoperable right after you power it on, so it’s no wonder this type of error can seem like something really serious. Fortunately, it is not as scary as it seems, and fixing it is quite easy. BIOS Basics In order to bios checksum error understand what triggers the BIOS checksum error, what the error means and how you can fix it, it is necessary to understand what the BIOS is and how it works. Simply put, the Basic Input/Output System, or BIOS, is a program that checks if all the components necessary for the computer to run are present; if everything is ok, the BIOS gives the processor the necessary instructions on how to proceed and load the operating system. Before the boot code in the BIOS is executed, though, the BIOS data is checked for authenticity by comparing one of its values, known as a checksum, against a value stored in a memory chip called CMOS; if the values match, it means that everything is working correctly, so the boot code is executed and the computer starts normally. However, if the checksums do not match, it means that something interfered with the BIOS, so the computer displays a BIOS checksum error and stops the boot process. Causes of BIOS Checksum Errors There are two scenarios that can trigger a BIOS checksum error: Something interacts with the BIOS code and interferes with the checksum it generates; Something alters the pre-defined checksum values present in the CMOS memory. The first scenario usually occurs when an incompatible piece of hardware is installed, as it will fail to pass the initial hardware check performed by the BIOS, and

Long story short I discovered several issues when I powered up this PC to ready it for a car ride to Florida that is leaving soon. 1. CMOS battery/Checksum error, removed old 2032 battery 2. I also removed a non functioning primary slave Seagate HD 3. Installed new battery 4. On reboot HD was not detected, auto and user defined HD did not work, system kept reverting to 9/1/1996 date. CMOS/Checksum errors continue despite new battery. Also moved jumper on HD to reflect single drive status. 5. Swapped power supply from CD to primary master HD (Western Digital) resulting in HD being detected. Used a different power supply cable for CD resulting in CD but no HD. Removed jumper from HD completely and tried a 3rd source for power to CD which worked, HD and CD detected, continued CMOS/Checksum errors mean Plug and Play enabling in CMOS is not being retained and must be enabled through setup to continue booting. AND with the cover off and the tight fit of swapping things in a desktop I also noticed that the CPU fan is not spinning. I am not sure when this happened, I was feeling heat on my hand all along as I manipulated cables. Good thing the cover is off. This fan is attached to the power cable I have attached to HD which meanes that it used to be piggybacking off CD drive not HD. My motherboard manual (FIC PA-2006) indicates that the CPU fan can be powered at a 3 pin connector on board to the left of CPU. CMOS/Checksum: Any ideas on how to resolve this issue? I can't send a newbie a PC that
