It is to take out the batteries of your mobo to reset the bios in case you can boot up windows...

It cant cause anything... just to restart to default options

And reset it by removing the batterie and unplug your power cord of you PSU for 10 minutes

The Cmos is where your mobo. will save to, when you save changes in your BIOS. To reset it, you should look for a calculator-looking battery on your mobo. and pull it our for about 15 secs. and then put it back in. No harm will be done, since the BIOS will just reset itself to its default settings, you may still have to change a few things, but after that, teh computer will be fine.

CMOS is this special moss that grows under the watch battery on the mobo--pop out the battery--wipe the moss of it and pop it back in--that's how you clear CMOS.

Contrary to popular opinion it does not come from the ocean or the C...and it is actually not Moss...but MOS...

Hope that helps..


But seriously. Just power of the rig unplug the 110 cable and opo out the battery then wait about a minute and pop it back in--this clears the information about whatever options are selected in BIOS and sets everything to default--even stuff you don't know about...

Other things will cause a no boot also, especially a bad stick of ram, don't just assume it is your mobo.

Could be CPU, unplug everything, you don't need drives to post, 1 stick of ram, check PSU also.

well only thing that happens is all the lights turn on and fans, same thing happens with it all plugged in

i cant figure out how to remove the clock battery thing, i have no tools under hand cause im at my bros apartment using his laptop trying to figure this all out o.o, its also pretty dark :/




is it possible my ram isnt compatible with my mobo and i fried the moboo cause of it? i just put ddr 400 ram, i think maybe the mobo supports up to ddr333, trying to look further into that, i thought it would just kinda underclock the ram tho...?
