Bios update my mb no power on .but i reset bios then power on . then after one hour no power on

make sure that all the power plugs are in the right place then check out the power supply

Try first resetting your BIOS configuration to bring it to its default settings and that should do the trick....

Hope that helps.........

hello, you will need to open your system unit, you will find a battery inside the motherboard remove the battery and refix it back. all the information on the bios will be cleared.

You cannot change the memory settings in BIOS. All you need to do is go into the bios screen. confim that it has seen your new memory and "save and exit" If it is not showing your new memory try removing and reinstalling the memory confirming it is installed correctly. it should just see it.

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.

Try removing the main battery and the CMOS battery (ie the battery on the mb). If you don't want to wait for 1/2 hour for the CMOS to discharge then short out the CMOS battery connections with a bent paper clip.
Then without instralling both battery, power up your laptop, you should then get into the BIOS, power off and re-install your batteries.

you updated the bios?

Its possible that your bios update failed and the bios is now corrupt.

try to rest the bios by th bios jumper, consult your manual or just remove the power and the battery for a hour and try again.

If the bios is corrupt it would need to be removed from the motherboard and reprogrammed.

Hello!

Bios update can be obtained from the manufacturer of your motherboard's website. If for example if your motherboard (MB) is made by DFI, then you can fine updates at DFI website. Please check your MB manual. Hope this may help you...

Does the motherboard support 1 gig ram modules? what kkind of motherboard/video card do you have? sometimes video card onboard ram can ofset motherboard ram, especially with ati video cards.

pull the bios battery for a few minutes and reinsert it , see if it comes back on.
