Cmos Checksum Error/ Cmos Checksum Bad???

so there was a CMOS CHECKSUM ERROR at the beginning of my problem. I decided to change the battery, and now i get a CMOS CHECKSUM BAD message and my problems still persist (BIOS/CMOS not saving, time and date are wrong and reset back to 2001 in november, and I STILL HAVE NO SOUND FOR SOME REASON!) is it time to move on to a new motherboard?

here's the backstory of my problem dating from a couple days ago:
i recently installed a prolimatech megahalem into my rig yesterday (great cooler, btw), and i notice i have trouble booting up (sometimes) and restarting (if i restart from windows or if i do some bios changes). i dont know what the problem is, and i don't think a CPU cooler could really make such chaos. i'm lucky to be posting this (because i cant boot to windows sometimes), but i need a solid fix for this. i also lost sound and while trying to get vista to recognize soundcard or onboard, it doesnt. any ideas?

 

Cmos Checksum Error/ Cmos Checksum Bad???

the cmos is located near 5v battery or close to clear cmos jumper

 

checksum error

4 year old foxconn diy box.
flashed bios successfully 3.5 years ago and everything was fine.

I have wiped HDD and reinstalled xp pro sp3 several times over the years. I decided that it was time again. Unplugged everything and air compressor blew out the box. plugged everything back in. On boot:
cmos checksum error
f1 run setup
f2 load defaults and continue

Ive never seen this before.

f2 usually lets it boot into xp

f1 I make changes, but on reboot it gives me the same error. On entering f1 again I see that no changes that I make stick.

moved jumper to reset. Put jumper back and still have this issue. Battery was 3.08 volts. Still I tried a new battery. Still have the issue.

old install of xp getting slower and more buggy, so decided to reinstall despite this issue. Reinstalled xp pro sp3 and my other programs early last month. Its much faster now and not buggy anymore, however I still have the checksum error, not that I expected this to fix it.

ideas to fix checksum error??

tks,
