Memory Error On Boot Up
that everything is working properly. Assuming that the BIOS is able to boot the system far how to fix bios error windows 7 enough to gain access to the video subsystem, it will display information what is bios 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.

Explanation: A parity error is occurring on a PC as it boots up. The parity error will typically occur as soon as the system completes the power-on self test; the memory count that is performed will typically pass without any problems being recognized. In some cases, when booting up Windows 95 or Windows NT http://www.dewassoc.com/support/bios/boot_process_errors.htm for example, the parity error will not appear until the graphical user interface of the Windows operating system itself comes up on the screen. Diagnosis: The most common cause of parity errors when first booting up the PC are incorrect configuration or using the wrong type of memory. It is unusual for an actual memory failure, of the type that parity checks for (meaning, you wrote one value into memory and read back another value with a http://www.pcguide.com/ts/x/comp/ram/parityBoot-c.html bit changed) to be encountered at the start of booting, although it is possible. Recommendation: Look on the screen to see if the system is giving you any sort of memory address that indicates where the parity error is occurring. Reboot the system and see if the same address comes up again, and then reboot a third time. Take note of whether or not the memory location changes, and then continue below: If the parity error is coming up as soon as the BIOS tries to boot, and especially if it fails at memory address "0000" consistently, this is a dead giveaway of trying to use non-parity memory in a parity system. Make sure that you have used real parity memory if you have parity checking enabled. If you are or were running with parity checking disabled, double-check the BIOS setting to make sure that it is still set as disabled. If it is enabled accidentally, parity errors will result. I have encountered a defect in the Abit IT5H motherboard, version 1.5, which will cause it to fail when using parity memory--it just does not work in this board due to a design flaw. Every time parity is enabled a parity error is generated immediately at boot time. It is possible that other motherboards may have similar problems.
