Did I kill my motherboard? CMOS Checksum Error - Page 2

post #11 of 24
Thread Starter 
Humm...well I removed the battery, but not for 15 minutes (maybe 5 or so). Everything is in pieces right now. I took apart everything in anticipation of having to replace my motherboard. Is it worth putting it all back together to remove the battery for a longer time period?

Does anybody have any theories about the CMOS checksum error? I hadn't ever heard of that before and it wouldn't make any sense to me that changing heatsinks would cause that error.

I've seen it quite a few times and usually clearing the cmos or restoring the default bios settings will get you around the issue. Also make sure to reconfigure your bios if there are custom settings you need for stability. As far as putting it back together I think it is worth a try for sure, if everything is out of the case I suggest to hook it all back up outside the case and test that way.

OK. I cannot put everything back together until tomorrow. The computer is at my Dads house and I am at my Moms right now. I'll remove the battery for 15 minutes, put it all back together, and report back. I really appreciate all the help, and hopefully this works....

Worst case scenario if it does not work, if I get an identical motherboard will everything boot fine without having to reinstall windows?

Thanks again!

Check all your connectors, push on everything, the obvious stuff. Other than that, look around the mounting points (screw holes or hooks) to see if maybe you might have shorted something out while installing the coolers.

With the magnifying glass the only thing I noticed was one capacitor near the southbridge was VERY slightly dented. But I wouldn't think it would cause this CMOS error.

no, unless the capacitor was bulging at the top with brown goop coming out, its perfectly fine. capacitors were a brief issue when some nitwit stole the wrong formula and spread it through the market, but they're not a problem generally and especially on a new board.

Thanks for all your help. + rep all around. I'm going to test these various things tonight and I'll report back. The only other thing I can think of is I just added 4 more gigs of ram as well. The ram is identical to the other 4 gigs I have in my system, but perhaps one of the new sticks is faulty which could cause this issue...

Well, new RAM is probably the problem then.
Try it with one of the older sticks first and see how that goes

UPDATE:

I tried removing the battery for 15 minutes and rebooting. No luck.

I cleared the CMOS. Again, no luck.

I tried each stick of RAM individually, but to no avail.

The only new thing I have to report is that I was able to press F1 when the CMOS checksum error came up. The computer tried to boot into windows. As soon as a flicker of the Windows logo came up with the progress bar below the windows logo I would get a BSOD.

The blue screen error said something to the effect of "damaged BIOS - not compliant". I've never gotten this blue screen before. I updated the BIOS to the most recent version and got the same BSOD every time (I even tried using each stick of RAM individually and then all the combinations of the pairs of sticks).

SOOO...I'm thinking I killed the southbridge, or damaged it just enough to make it non functional, but I really don't know. Newegg has an open box version of my motherboard I can get overnighted for 80 bucks. I'm thinking about pulling the trigger on that and hoping for the best. Any new thoughts? If I get an identical motherboard, will I be able to put it together without reinstalling windows? The last time I backed things up was 3 months ago, so I'd really like to avoid a fresh install...

If you put the exact same motherboard in in replacement of your supposedly dead one, then you should be fine. One thing to try (although it seems odd) set your date and time to something new, even if it's wrong. And see if that makes a difference.

Best of luck!
