Bios Checksum Error
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 bring back to life a computer that hasn’t bios checksum error gigabyte been used for a long time. If it sounds like a scenario that’s not
Bios Checksum Error Fix
very likely to happen to you, think again, as computers became so un-complicated that you don’t need to be working at main bios checksum error gigabyte 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 cmos checksum error fix 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.
Checksum Error On Boot
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

hassles Home Hardware Troubleshoot a BIOS or CMOS 'Checksum' Error Comments By Rick Broida, PCWorld Sep 21, 2011 9:40 AM Reader Robert has an older Emachines desktop that recently https://blog.udemy.com/bios-checksum-error/ developed a problem: "I installed a driver updater tool, and when I deleted it, it did something that changed my BIOS. 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 contacting both Phoenix Technologies (makers of the BIOS) and Emachines, http://www.pcworld.com/article/240331/troubleshoot_a_bios_or_cmos_checksum_error.html 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 one, pop in the new one, and you're done. After that, you'll probably need to venture into the BIOS to r
CMOS setup and check all values, this includes verifying the time and date are correct. Once everything has been verified and changed make http://www.computerhope.com/issues/ch000237.htm sure you save settings and then exit CMOS setup. If everything appears https://www.youtube.com/watch?v=IC3ZdfWUx1w to be correct, you can try resetting the CMOS to the default values. After the CMOS values are reset, save changes and exit the BIOS to reboot the system. Tip: If this issue continues to occur after you turn off your computer off the CMOS battery may be failing or already checksum error bad. Before considering replacing the CMOS battery try leaving your computer on for several days. Sometimes leaving the computer can re-charge the battery. How to replace the CMOS battery. Computer improperly turned off If the computer lost power while it was still running it may have corrupted the CMOS. Make sure the computer is ready to be shut off before turning off the bios checksum error computer. If you have a laptop computer make sure the battery is charged before disconnecting the power connection. If the CMOS values have become corrupted enter the correct values in CMOS setup and then save and exit CMOS setup to resolve your issues. BIOS update recently performed If a BIOS update has been run on the computer the values stored in CMOS may have been reset. Enter CMOS setup re-enter all values and then save and exit CMOS setup. If you are unable to enter the CMOS setup, or the computer no longer keeps its BIOS values, the BIOS update may be corrupt. In this case, we recommend updating the BIOS again or reverting to an earlier version.
