POST Error Occurs! CMOS Checksum Error - Defaults Loaded, press F1 to Continue

Good Morning, before I start I want to apologise for repeating this topic, I am fully aware it is present on other threads, all of which I have read.

Around three weeks ago, I installed an Asus Xonar DSX 7.1 Surround Sound Card, onto my motherboard. Upon boot up, I see my motherboard splash screen, and then a blue screen. The following message occurs:

Post Error Occurs!
CMOS Checksum Error
Defaults Loaded
Press F1 to Continue

I am then given a choice of profiles which I can load, by selecting them with my arrow keys and hitting enter. I am also given the choice to load 'Last Known Good'.

Now, I know how this sounds, you will typically say CMOS Battery. Below is a list of the things I have tried:

Resetting and Reseating the CMOS Battery ( I have to remove the Sound Card to do this then replace it when I am finished)

Changing the CMOS Battery

Leaving my PC on for 12 hours

Removing the soundcard and booting without it.

Now, just to be clear, this issue happens on every boot, and a small 'click' can be heard, it sounds electrical, like something is discharging.

I am forced to manually reset the date and time every time I get to my desktop, and some of my icons do not show in the notification area, and my default programs (EVGA Precision X, Corsair Link) do not load.

If I try to reboot, even two or three times to get my default programs back, the date and time stays the same, but my PC Hangs terribly (task manager fails) on desktop, forcing me to reboot several times.

Now, I have been told that this could either be a motherboard or PSU Issue. I will list my specs below:

CPU: AMD FX 8320 - Black Edition Octo Core Processor (Vishera)
GPU: NVidia GeForce EVGA GTX 780ti SC (w/o ACX cooler) 3GB
Cooler: Corsair H100i Hydro Liquid Cooler
RAM: 16GH Corsair Vengeance 1333Mhz (2x8)
PSU: OCZ Vertex ZS Series 750W (Non Modular)
Motherboard: Gigabyte 970A-DS3
Boot Drive: OCZ Vertex 128GB SSD
Main Drive: Seagate Barracuda1TB 7200rpm HDD

This issue is driving me insane, and I refuse to believe that a CMOS battery could cause this because I have tried everything apart from jumping it (something which I am neither willing or confident enough to do) and even changing it didn't work, and yes I did use a 3V 2032.

Any help would be massively appreciated!

Thanks

1 To enable AM3+ AMD FX-Series CPU support, please update your motherboard with the most current BIOS found in your motherboard's download section.

2 replace the motherboard as soon as possible ... this model is no longer available because of his hardwares problems

There were no unusual smells when I first did it. Also, how do you know that the Motherboard is no longer available, please could you provide proof of these hardware problems? The vendor that sold me my PC (Custom gaming rig) gave me this motherboard as standard.

your cpu is not supported with this crap motherboard
even with the rev 3.0 mobo
this mobo is not built for cpu with 125W tdp
only the GA-970A-DS3P model support 125W tdp

It specifically says supports AM3+, which means that it should work, and also the fact that I have been using it for over a year with no problems whatsoever...but I can understand what you are saying. What would you recommend I replace it with?

Just because it says am3+does not mean it supports the 8350 which is a 125 watt chip an fx 4300 is am3+ but much less voltage.

Okay, Thanks so much you guys, the people I got it from said they would fix it under warranty. But this would take 5 days minimum, which is far to long! What would you recommend I do?
