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).

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 ????

Reports: · Posted 4 years ago Top semiretired Posts: 1214 This post has been reported. Cmos equals continuous metal oxide semiconductor. It is the small disk battery found on your motherboard. It is usually a cr2032 that can be purchased at a walmart......etc. In a laptop, it could be sheathed in a holder of some type and be more expensive.

What Does Cmos Checksum Bad Mean
AM Reader Robert has an older Emachines desktop that recently developed a problem: "I installed a driver updater tool, and when I deleted it, it did something that changed my BIOS. http://www.howtogeek.com/forum/topic/bad-bios-checksum-how-to-fix-it- 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 could help. (The BIOS dates back to 2003, and the system itself is long out of warranty.) Fortunately, this sounds like a http://www.pcworld.com/article/240331/troubleshoot_a_bios_or_cmos_checksum_error.html 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 system settings (like boot priority). Just be glad this didn't happen to your laptop. Laptops use CMOS batteries just like desktops, but on most models they're difficult--if not impossible--to replac

I recently formatted my computer running windows xp and bought windows 7 to upgrade it. When I upgraded the computer it was getting very high CPU spikes without me running hardly anything at all and so I decided to update my bios but now when my computer starts up it says Press F1 to run SETUP or F2 to load default values and continue. cmos checksum bad When I go into setup it takes me to the blue BIOS screen and F2 starts the computer. Incidently the computer still has the high CPU spikes so the flash hasn't really done the job I wanted it to do so I'm pretty stuck now. My board details pre the update we're as follows:MS-7350 1.0, Bus Clock: 267 megahertz, BIOS: American Megatrends Inc.

If you have done this and the settings are not being retained then it may be that your battery is dead.Or it may be that you need to clear the CMOS (your motherboard manual should tell you how to do this -
