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, and neither company lỗi bios checksum error 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 reset the clock and double-check other syst

a scenario that’s not very likely to happen to you, think again, as computers became so un-complicated that you don’t need how to clear cmos checksum error 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 http://www.pcworld.com/article/240331/troubleshoot_a_bios_or_cmos_checksum_error.html 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 https://blog.udemy.com/bios-checksum-error/ 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 tha

Around three weeks ago, I checksum error installed an Asus Xonar DSX 7.1 Surround Sound Card, onto my motherboard. Upon boot up, I see my motherboard splash screen, and then a blue screen. The following message occurs: Post Error Occurs! CMOS Checksum Error Defaults Loaded Press F1 to Continue I am then given a choice of profiles which I can load, by selecting them with my arrow keys and hitting enter. I am also given the bios checksum error choice to load 'Last Known Good'. Now, I know how this sounds, you will typically say CMOS Battery. Below is a list of the things I have tried: Resetting and Reseating the CMOS Battery ( I have to remove the Sound Card to do this then replace it when I am finished) Changing the CMOS Battery Leaving my PC on for 12 hours Removing the soundcard and booting without it. Now, just to be clear, this issue happens on every boot, and a small 'click' can be heard, it sounds electrical, like something is discharging. I am forced to manually reset the date and time every time I get to my desktop, and some of my icons do not show in the notification area, and my default programs (EVGA Precision X, Corsair Link) do not load. If I try to reboot, even two or three times to get my default programs back, the date and time stays the same, but my PC Hangs terribly (task manager fails) on desktop, forcing me to reboot several times. Now, I have been told that this could either be a motherboard or PSU Issue. I will list my specs below: CPU: AMD FX 8320 - Black Edition Octo Core Processor (Vishera)
