i tried to clear cmos, now it won't power up. i had the computer still plugged in, just powered down, when i did the clear. as soon as the jumper went back into normal position, the thing powered up on it's own, so it had juice without the battery in place. i think this might have helped kill it (confirm / deny??)

so now it turns on the fans, and just sits there. no post, no nothing else.

i am thinking that if i have the bios chip reprogrammed or get a new chip, i might save the board.

any experience with buying bios chips?

it's kind of tempting to try to get a chip programmer myself - might be more fun/satisfying. any thoughts/ recommendations there??

thanks everyone :-)

Have you tried resetting it the correct way?

Like, with the power turned off, the computer unplugged, after hitting the power button a couple times to let all the juice out of the capacitors?

There you go.

I dont have any experience getting new BIOS chips. I suspect that it would be more of a pain than it is worth, however.

did you just move a jumper from one position to another to clear cmos ram ?

if so its possible you zapped the system with a charge imbalance , did you earth /ground yourself first ?

tokaok

take note you shouldnt unplug your pc went messing around inside of it. just turn the power off at the back. that plug is as close as a ground as most are gonna get.

Bios chips are kinda a pain in the ass to get...I remember getting one for a abit board and it was around $20....and that isn't a guarantee fix.....The best best is buy a new board and ebay your old one as a fixer upper..

So, you had your cmos battery out when you tried to reset the cmos?

It (cmos) runs off the battery to save info about what computer it is installed in and what the user choices are.

This is something worth reading; "The CMOS or Complementary Metal Oxide Semiconductor is an on-board semiconductor chip. Which requires very low power generated from various types of CMOS batteries which are shown below. This chip is used to store important system information and configuration settings while the computer is off and on."

Try starting fresh. Remove the cmos battery again. Let the machine sit for the time it takes to enjoy dinner and drinks with freinds. Go to Walgreens and buy another battery, take the old one as a sample. When you get home, reinstall the new battery. That should restore default settings for the system.

After you have done that, repost and tell us what has happened.

Oh, one more thing. ALWAYS unplug the power supply before disconnecting, unplugging things from your mobo.

Let us know what happens.

As a reminder, you should never reset the CMOS when overclocked. That'll fry your motherboard rather quickly in some cases. I don't think you had it overclocked, so that's not the problem. Just try every method of resetting it like the previous replies. That's how I fixed my Abit NF7-S whenever I overclocked the RAM too far.

thanks yall

i have not tried hitting the power button while it's off, but i have run through the cmos clearing procedure with the power unplugged several times - nothing.

at the store, they say they will send the board out for servicing for free, but may take up to 6 weeks. :-(

so you guys think there's hope without replacing the chip? i've cleared it so many times now i'd pretty much given up on that...

i usually leave the power supply plugged in for grounding reasons when i'm in there, but admit there are potential problems there.

seems most people who have similar problems were doing a flash, but i wasn't even to that point yet so maybe there's hope. one interesting thing: the whole reason i was clearing cmos was because the bios update utility would say 'no asus board found' or something like that, even though it showed up correctly in asus probe, etc.

new bios chip from badflash.com got it going again. then i hot-flashed the old chip, which i'm using now. so now i've got a spare
