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

 

CMOS Checksum Bad: First time PC builder MSI 790FX - GD70

ensure the bios reset switch isnt pressed (if that motherboard is equipped with such) or the jumper cap is in the right position(clears the CMOS). Normally CMOS Checksum issues are battery or the clear CMOS jumper cap not in right position.
