Penryn1600sli-110db CMOS CHECKSUM BAD ERROR

Hi.

Exist some problems that can cause that:

1- The CMOS battery. Solution: Change it for a new one.
2- Some problem with the time specifications in the BIOS.
3- Some drive that isn't connected properly.

Unplug power remove battery try to turn comp on several times replace battery plug in power & you should then have to set everything in bios done

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 you suspect that your CMOS battery is not functioning properly, you can easily change it. Before changing your battery, reboot your computer to make sure that the error still exists. If it does, go into your CMOS and write down all of the settings. If all the settings are lost, you can usually retrieve them from your computer manufacturer. Now locate the battery and remove it, you might need to consult your computer's manual or technical support to remove your battery (the battery a flat, shiny silver colored and coin-shaped). Take down the CMOS battery's information such as volt, size, etc. Once you have your new battery, you can replace it and reenter your CMOS settings. If your battery was the cause of the CMOS Checksum Bad Error, you should have solved the problem.

Your BIOS may have been updated

If your BIOS have been updated recently, your 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 you believe that a virus has updated your BIOS settings, run a virus scan and make sure that the BIOS settings are back to the default.

The Computer may not have been shut down properly

Sometimes when running MS Windows, if you shut down your computer without first properly shutting down your operating system, it will corrupt the CMOS settings causing the CMOS Checksum Bad Error. You can easily avoid this error by making sure that you completely shut down your computer properly before turning off the main power. Usually this entails going into the Start Menu, clicking on Turn Off Computer/ Shut Down. If improper shutdown was the cause of the error, you may have solved the issue.



akuma_ryu21 rate it pls!!

There are usually three main reasons that a CMOS Checksum Bad Error has occurred. They include:

• CMOS Battery may not be functioning properly. The battery life may have expired.
• Your BIOS may have been updated (either by user or possibly a virus)
• 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 you to shut down your computer before shutting off the power).

Hi there.
Basically you first bios update was bad, if you can get into the operating system re-flash the bios again, that will sort it out.

Good luck and thanks for choosing FixYa!!

That sounds like a classic case of a dying cmos battery.

if you have vista you could do a memory check in the boot options by resarting computer and key f10 boot options, then find memory check witch will display any errors with soloutions.

Hi,

If you have recently upgraded your motherboard and when you turn it on, there is no display. You could check the jumper setting of your motherboard.

http://download.asrock.com/manual/PENRYN1600SLI-110DB.pdf

Check this site for jumper settings. Download the manual. Go first to page 11 and find clear CMOS jumper. That will be number 17. Then go to page 24 for the correct jumper settings. Jumper should be on the pins 1 and 2. That's the default settings.

If the jumper is set already to 1 and 2. Clear the CMOS by putting the jumper on 2 and 3. It should be off when you are going to set the jumper. This is to make sure that the settings for your motherboard is set to its original settings.

If you are going to clear the CMOS settings, you will have turn the computer on after clearing it and then turn it off again. Put the jumper back to pins 1 and 2. Now make sure that computer is totally off. Uplugged the computer just to make sure when you are doing this.

Note:
To test also the motherboard if it is working, do not connect the other pheriperals such as network card, sound card, and other cards that is not buit-in. Also drives such as Hard Drive and CDROM drives.

Check for beep codes. Short beeps tells you that the Video card is not inserted properly. Long beeps tells you that the memory card is not in place correctly.

Just remove the Video card or Memory card and then place it back again.

Computer should be off as well when doing this.
