First switch off at wall and remove power leads. The push on button to discharge capacitors on board.

 The jumper will be located near the bios battery and chip usually at the bottom right of motherboard. Move the jumper to the clear position and leave for a few mins. Then put back into normal postition and start pc up.

If that fails to clear it then repeat but remove the battery from the motherboard too and wait longer.

Hope that sorts it for you?

HOLD del key even before you start your computer, then you start your computer.
If that doesn't help, open your computer and clear CMOS on motherboard, find jumper called clear cmos, but first un-plug Power or turn it off (put switch to 0), then put jumper in clear CMOS for couple of seconds, then try turning it on, ..

If one slot doesn't work, I suggest you try free program: memtest86 ! IT will show you if you have slot or memory problem.

If none from above helps, put one memory out, then try, then put another in, and other out and try.

Hope it helps.

You can clear CMOS by shorting 2-3 pin while the system is off. Then return to 1-2 pin position.

Hi... i have gigabyte ga-945gcm-s2c and i dont know where is the jumper to bios clearing CMOS... please help me to fix this problem... thanks before....

You can get the manual here:

But if you look to the right of the CMOS battery, you will see two pins, to reset the cmos, simply cap the pins with a jumper for 10 secs, or touch them with a screwdriver (mains power OFF of course)

How to clear cmos in asus a7n266 mb

I had similar mobo and this is what the Asus technician told me. Take out the round battery in your motherboard and flip it around and put it back into the battery slot.(it sounds weird but that is what he said) Hold it there for 20seconds and then put back in the right way it was.

Your cmos should be cleared now. Make sure your pc is switched off when doing this.

Soltek sl-k8trpro939, error message BIOS not Loaded,

To clear cmos you'll need to remove the cmos battery from the motherboard for about 5-10 seconds then replace. You need your motherboard disk in order to load the bios. If you do not have this disk then you will need to go to the board manufacturer's website & download the bios. Follow the directions they have at the site to make a bootable disk & then boot from this disk. Hope this helps & please remember to rate my answer. Thanks.

Need to reset Asus k7v bios

Yes, if you consult your motherboard manual this will show you the location of the cmos battery and reset jumpers. You can either move the jumpers from pins 1+2 to 2+3 and then back again after a few seconds or remove the cmos battery for a few seconds. Make sure your pc is off!

Please help me


Check ASROCK P4i45GV R5.0 User Manual Page 17 -

Note: Check Page 11 for the CLRCMOS0 location on the motherboard. From the picture CLRCMOS0 is number 18. You can locate CLRCMOS0 just below the CMOS Cell Battery.

Turn off the computer and unplug the power cord, then use a jumper cap to short the pins on CLRCMOS0 for 3 seconds. Please remember to remove the jumper cap after clearing the CMOS. If you need to clear the CMOS when you just finish updating the BIOS, you must boot up the system first, and then shut it down before you do the clear-CMOS action.
