computer's data is intact and unhampered. The data is scanned and tested for accuracy, either based on how well it relates to data elsewhere or based on previous data that was stored on the same computer. Essentially, all of checksum error winrar the bits of data in a particular document or file are added up and a number checksum error in the encrypted file winrar or hash is created. This number or hash can then be compared to the number or hash generated from the same file on another person's

computer or at a previous time on the same computer. When does a Checksum Error Occur? Although a checksum error can occur at any time while a computer is comparing data, it is most commonly present during a computer's startup
Checksum Error On Boot
procedure. During a computer's start up processes, the BIOS settings, which are stored in a CMOS memory chip, are computed and then checked against the previous value. If the computed values do not match exactly, the computer warns the user with a checksum error message that the data may have been changed or corrupted between start up cycles. All BIOS programs present a different error and therefore will either continue with booting or refuse to boot until the problem is corrected. Depending checksum error windows 7 on the type and the severity of the error generated, there may be one of a variety of ways to rectify the issue. The most common cause of a checksum error during the startup process is a faulty battery that is not providing sufficient power to the motherboard when the computer is off. However, motherboard malfunctions and viruses can also contribute to checksum errors. Other Types of Checksum Errors Another type of checksum error may occur with any program at any time. It is usual for many programs to now provide checksum information when that program is downloaded. Using a checksum program or MD5 hash checker, a user can quickly compare the checksum of a downloaded program with the checksum that the software developer provides. This is a common way to make sure that users are downloading the proper program and that no data was corrupted during the download process. Checksum errors originating from download errors can easily be corrected by re-downloading the problematic program. Follow Us!

Causes of CMOS Checksum Bad Error There are usually three main 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 ????

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. If it sounds like a scenario that’s not very likely to happen to you, think again, 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 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, 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 thus return a BIOS checksum error. A BIOS checksum error can also be generated by an incorrectly performed overclocking process
