Some motherboards will switch on and run after removing the cmos battery also but in some motherboards it is not possible it depends on the manufacture design ...

try changing the cmos battery with the new one that cmos battery might have lost it s power ...

after that also if you face the same problem then there may be some dust particles accumulating in the processor fan due to that it might not be able start clean them and refit and try it ....

if you still face the same problem then if you are using UPS then remove the connection from that and give the direct connection this may solve your problem if there is some problem in the UPS battery ....

any doubts you can reply me

    there is no use in answering you now bcoz you already rated me only" thanks for trying" ...

    but also here is the answer on your comment on how to update the bios ...

    in your motherboard cd there is software something called as" online bios update" or something like this first you install that then connect to internet it will automatically download the bios update for your motherboard model and it will install it automatically in windows mode only ..

    but remember never turnoff the pc while bios update is in progress it will destroy the current bios and your pc booting will be failed after that you must recover the bios by changing the jumper to recovery mode so never do that ...

    if you dont have it in motherboard cd then you can download it from your motherboard manufacture site or you can download it in the following websites

    if you think this answer is worth for you then you can change the rating which you have rated previously by clicking on the daimond...

    thank you

    @khankaram10 ...

    as i think your motherboard is intel 915 if this is right then you can download the bios update directly from the intel website and you can just execute that file in windows platform and it will upgrade your bios ...

    but remember never turnoff the pc while bios upgrade is in progress ... it takes some 3-4 mins that s it ...

    given below is the website where you can download it ..

    after going to this site you can select your exact 915 motherboard model and you can click on Latest bios to get the bios update for download

    thank you

Main bios error for gigabyte gag31 fsb1333

Hello try to download a manual for trouble shooting
just select the right model here:

The number is printed in on the mainboard by the pci socket.

Have you tryed to upgrade the bios ???
Whats the fault in more details ???
Any visible faults ???

Try to renew the cmos (cr2032) battery:

And try to boot again.
You have to setup the clock and the boot settings for the drive.
Because removing the battery will reset the bios to factory defaults.

A fault in a graphic card or drive can also cause this.

Good luck

I want to reset BOIS password for Gigabyte GA EP43 motherboard which has no jumper, i try to remove battery but the problem unsolved~

There is a CLR CMOS jumper on that MB next to the SYS FAN 2 connector by the IDE header

open = no clr
jumped= Clear CMOS

From the manual page 32

Use this jumper to clear the CMOS values (e.g. date information and BIOS configurations) and

reset the CMOS values to factory defaults. To clear the CMOS values, place a jumper cap on the

two pins to temporarily short the two pins or use a metal object like a screwdriver to touch the two

pins for a few seconds.

• Always turn off your computer and unplug the power cord from the power outlet before

clearing the CMOS values.

• After clearing the CMOS values and before turning on your computer, be sure to remove

the jumper cap from the jumper. Failure to do so may cause damage to the motherboard.

• After system restart, go to BIOS Setup to load factory defaults (select Load Optimized

Defaults) or manually configure the BIOS settings (refer to Chapter 2, "BIOS Setup," for

BIOS configurations).

Remove the CMOS battery in the motherboard for some time and then plug it again the bios will be reset to factory defaults with no password. CMOS battery is like a coin in the motherboard with positive sign (+) in the upper side.


In the motherboard there is a bios reset jumper, it has three metal with two of them was use by the jumpers as the default, just move the jumper place it occupying the third metal point leaving the first. wait for about 1 min then return to the original setting occupying the 1st point, turn the unit on and CMOS will be cleared off.

Gigabyte Socket A GA-7VA Bios update failure

You can try to save the motherboard w/ a floppy, and if that doesn't work, go to gigabyte's website and request for an RMA. I made the same mistake in trying to update the BIOS through @BIOS after it updated, it assked for me to restart the pc, and when i did, the was nothing. All i heard were the fans. Nothing on the screen, and it obviously wasn't posting. So go to Gigabyte so you can get another one, and tell them there's a flaw w/ the application @BIOS. If by any chance you update the BIOS, try it w/ a flash drive under DOS. Good luck.

Cmos checksum bad...usb current status detected system shut down 15 sec

Situation Remedies If you have encountered this error and would like to fix your computer, here are some remedies for each situation:
CMOS Battery Not Functioning Properly: If you suspect 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 settings are lost, you can usually get them from your computer manufacturer. Now locate the battery and remove it, you might need to consult your computers manual or tech support to remove your battery. Take down the CMOS batteries 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 remedied the problem.
Your BIOS has Been Updated (either by you or possibly a virus): If your BIOS has been updated recently, your CMOS settings may have become 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 updated your BIOS settings, run a virus scan and make sure that the BIOS settings are back to the default.
The Computer Was Shut Down Improperly: Sometimes when running MS Windows, if you shut down your laptop or desktop 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 before turning off the power. Usually this entails going into the Start Menu/ Turn Off Computer/ Shut Down. If you received the error, shut down the computer properly, if this is the cause of the error, the error message will not return.
