CMOS battery drains after one startup. Gigabyte GA-K8N-SLI

I upgraded the bios months ago and everything seemed OK. Later, I added a second DVD to my DVD burner. Wanted to read write to burn DVDs in one quick motion. I started to notice that it took a second push of the start button, then a third time before it work turn on the computer. Then it wouldn't start at all. I took out the CMOS battery and found it dead. I installed a new one. It worked fine for about a week when the symptoms started all over again. I installed a third battery and this time the battery was completely drained to a dead battery after one startup. Any help out there? gigabyte GA-K8N-sli amd 3800 x2 1.5g of memory evga e-gforce 7600gt sli video card 650 power supply

Re: CMOS battery drains after one startup. Gigabyte...

OK lets see here! Make sure your CMOS jumper is set properly on the board(Set to Normal) or Did you configure your bios after flashing the bios(going into bios and Load Optimized Defaults!)? or I don't think it would be another device in the system, but you can try troubleshooting by starting up with only what you need to run the machine (Mobo, memory harddrive, keyboard and mouse) then one by one adding devices back! or Did you have problems like this b4 you flashed the bios! Try flashing the bios back to an older version! post back if anything new or if i'm way off! Good Luck regards, babb

check your motherboard manual fo CMOS reset jumper location on you motherboard, and follow the instructions on resetting to defaults. Keep in mind that any customisations implemented by you in bios will be lost, so you will need to do them again.

Hope that helps

Remove the hdd and try again. If now you can enter the BIOS and check that everything is correctly recognized and configured then the hdd has died, replace it. If it's the same then start by checking the power source, followed by the memory and the CPU. If all these are functioning then the problem is in the motherboard itself - unfixable, replace it.

Replace motherboard battery..... what after i mean the BIOS settings

when the CMOS battery is replaced the default Bios settings are retained, if u made any custom changes to Bios then u will need to do them again, things like boot menu processor speed settings ect. are you clear on this, 99% of time it changes nothing since most users don't even know what Bios is or how to alter it.
