Bios Checksum Error Memory
Contents |
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 main bios checksum error gigabyte bring back to life a computer that hasn’t been used for a bios checksum error fix long time. If it sounds like a scenario that’s not very likely to happen to you, think again, as bios checksum error solution 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 bios checksum error beheben 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 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 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

The black screen appears when I boot up and reads: 'System BIOS shadowed. Check time and date settings. System CMOS checksum bad--default configuration used.'" Robert says he's tried http://www.pcworld.com/article/240331/troubleshoot_a_bios_or_cmos_checksum_error.html contacting both Phoenix Technologies (makers of the BIOS) and Emachines, and neither company could help. (The BIOS dates back to 2003, and the system itself is long out of warranty.) Fortunately, this sounds like a pretty easy problem to fix. I don't think the driver-update utility is to blame here, but rather a poorly timed CMOS-battery failure. See, most desktop motherboards have a small battery that supplies power to the BIOS even when the machine is turned off. This battery might last two years or it might last 10, but when it fails, you'll often see an error message like the one above. (Your system will also fail to keep proper time, as the clock is one of the elements powered by that battery.) Most CMOS batteries are standard CR2032 "button" cells, which cost no more than a few bucks at your local drugstore, but check your motherboard documentation just to be safe. Replacing one is usually a two-minute job: pop out the old o

Apparently after a power outage the PC would not boot and we were not able to get into the bios screen. I removed battery and also reset CMOS but still no changes. So powering the psu on/off, we got the screen displaying bios checksum error. The mobo is an Asus M4A78 Pro. I went to the ASUS site on another computer and downloaded a new bios bios checksum error onto a mem stick. Tried installing the new bios and although the screen said it had loaded/ erased/re-prorammed the new bios, the PC still does not boot. I am not sure what else to do. I may try removing RAM, changing CPU etc but wondering if its the bios chip itself ? If It is can I get a new chip. I am a technition so I would be able to replace it. Just want it to be the last resort.

How many times have you flashed the BIOS in the past? It's usually a lot of write cycles that
that everything is working properly. Assuming that the BIOS is able to boot the system far enough to gain access to the video subsystem, it will display information about the PC as it boots. It will also use the video system to communicate error messages to the user. In fact, most boot problems are displayed via video error messages, as opposed to audio beep codes. For more information on beep codes, see AMI Beep Codes or Award Beep Codes. An error message can be produced by various different parts of the system during the POST process, depending on how far into the boot process the system gets before it is occurs. Most error messages are produced by the system BIOS, as it is responsible for most of the functions occur during boot. Other error messages are operating-system-specific. There are many thousands of individual error messages; some are more common than others because there are only a few different BIOS companies that are used by the majority of PCs out there today. You should note though that the exact wording of an error message can be changed by the manufacturer of each system or motherboard, thereby providing for a multitude of variations. In most cases, the messages are pretty similar to each other, and you may see slightly different wording in the error message you see as opposed to the ones listed here. Essentially though, if the messages appear similar, it is probably safe to follow the diagnosis here. "Disk drive failure" and "Diskette drive failure" are what we would consider similar in nature, however you may want to consult your motherboards owner's manual regarding any unusual messages, or to ensure that your manufacturer means the same thing with their messages that other companies do. Additional Notes: We have tried to list all the error messages in alphabetical order for simplicity, however you may find a few that appear out of order. These were intentionally inserted out of order to place them with error messages that are similar or fit a certain category. Some BIOS POST messages you will see in all UPPER CASE and some will be found in a mix of UPPER and lower case. We have used the mixed upper and lower case for easier reading.
