Cmos Checksum Error On Boot
profile. Yesterday i was checking my email and watching a video on you-tube when suddenly I got a blue screen. At this cmos checksum error press f1 to continue time, it showed a memory dump go form 0-100%. I don't really remember much else besides that. But seconds after, my screen goes black. I anticipated a reboot to follow up like it normally would, but it remained a black screen so I hit the restart button and all I saw was: ___________________________________ Award BootBock BIOS v1.0 BIOS ROM checksum error Detecting IDE ATAPI device ... Found CDROM, try to boot from it ...Fail INSERT SYSTEM DISC AND PRESS ENTER ___________________________________ Some extra information: -I did overclock my processor about 4 months ago from 2.4 to 3.0 without any thermal paste =P and then more recently, I OC'ed it to 3.2 about 2-3 weeks ago. From what I can remember, I don't think the CPU temps ever went over 55C. But, I've had it OC'ed for a while, so wouldn't this have happened a long time ago? -My computer is always on 24/7. -It is a custom machine I built myself no more than a year ago. -While I was browsing other sites to find a solution to this problem many people that had the same error said that they can go into their BIOS by pressing F1 or DEL but, I do not have any options other than "insert a disc and pray"... I did some research on this error message yesterday and today. I can tell you what I did to try and fix this issue: -I removed CMOS battery and then replaced it after 10 mins. Nothing different happened. -I did not replace the CMOS battery with a fresh one since the computer is so new. I could not imagine that It would be defective already. -I reapplied thermal paste... (well, in my case, applied thermal paste to the CPU). Nothing different happened. -Used Phoenix Award BIOS flash tool to flash the BIOS (did not want to do this at first since i am working with an OC'ed motherboard). This was strange
fix it if I get a CMOS checksum error (battery replaced)?I have a asus P5B-SE motherboard and when I boot I got CMOS checksum error.First I thought that there was battery problem so I installed a brand new battery but it still happen.What's the problem? How to fix it?UpdateCancelAnswer Wiki4 Answers Brock McKean, I'm a computer engineer and entrepreneur. I train people to code by habit.Written 122w agoIf it was still in warranty I would suggest contacting Asus, but I assume it is not. Contact Asus directly anyway and ask them if there is anything else you can do. Perhaps there's some way to flash it or do something else only Asus would know to do. They http://www.tomshardware.com/forum/269599-30-nvidia-750i-bios-checksum-error will advise you further. If you've already replaced the battery I'm sorry to say I don't think you're going to hear good news from Asus. They'll probably want you to ship it to them for repair and pay for the return shipping as well, since it's not under warranty.However, this is not what I would suggest. I'd say go get a new motherboard, because paying to repair yours is probably going to cost enough that you https://www.quora.com/How-can-I-fix-it-if-I-get-a-CMOS-checksum-error-battery-replaced might as well just buy a new P5B-SE. Of course, I don't think you'll be able to find a new one, so you'll need a different one. If you go that route, you'll probably need a new processor at least, and probably new ram, but it's about time for you to upgrade anyway. Also, don't buy Intel unless you really feel like you need it for a specific purpose. It's overpriced and not rarely provides performance gains that are notable as a generic or even power user. AMD is much more robust in its ability to upgrade and maintain system continuity in a situation like this. Their Zambezi architecture is actually really powerful in applications that utilize several cores, and overclocking AMD processors is a matter of temperature mainly. They're very sturdy and can handle a lot of OV as long as you keep the temperature down.If you really want to stick with the system you've got there, pick one up from ebay. They're really cheap and not brand new, but cost about as much as you'll probably have to pay in shipping.3.3k Views · View Upvotes · Answer requested by Ivan CaiRelated QuestionsMore Answers BelowI have an HP 8560W laptop.

the CMOS Checksum Bad Error, hence they can be handled effectively. The Error Explained A checksum is computed as an error detecting code to guard the BIOS settings stored in the CMOS memory. The CMOS Checksum Bad Error is an error that occurs when http://www.tech-faq.com/cmos-checksum-bad-error.html the CMOS values turn out to be incorrect. The CMOS memory stores a specific value normally to guard the BIOS software. Each time the computer is booted, this value, which is a number is checked against the stored value in the CMOS memory. If these two values are different, it causes a CMOS Checksum error message. If these values are the same, the computer boots normally. Each computer usually deals with the CMOS Checksum Bad Error differently. Some computers warn the user and continue checksum error to boot up using settings in the CMOS, while other computers might warn the user and use the default settings in the BIOS as the correct settings and carry on with a normal boot or reboot. Usually, the strategy the computer employs is stated in the error message. Causes of CMOS Checksum Bad Error There are usually three main reasons that a CMOS Checksum Bad Error occurs. They include: CMOS Battery may not be functioning properly. The battery life may have expired. The user or cmos checksum error a virus may have updated the BIOS. 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). Solutions to CMOS Checksum Bad Error The CMOS Checksum Bad Error can be fixed easily by following the listed steps carefully. CMOS Battery May Not be Functioning Properly If the user suspects that the CMOS battery is not functioning properly, he/she can easily change it. Before changing the battery, reboot the computer to make sure that the error still exists. If it does, go into the CMOS and write down all of the settings. If all the settings are lost, they can usually be retrieved from the computer manufacturer. Now locate the battery and remove it. Consult the computer manual or technical support to remove your battery (the battery is flat, shiny silver colored, and coin-shaped) if needed. Take down the CMOS battery’s information such as volt, size, etc. Replace the old battery with a new one and reenter the CMOS settings. If the battery caused the CMOS Checksum Bad Error, the problem should be solved. The BIOS May Have Been Updated If the BIOS was recently updated, the CMOS settings may have reset. Make sure that the values entered in the BIOS are correct or simply reset them to the default settings. If a virus has updated the BIOS settings, run a virus scan and make s
