Don't know what to tell you about the Nvidia card.
Are your System Specs correct? It says you have a
MSI GT70 0NC which is a laptop and would not have 4 memory slots of room for a Nvidia card. See here: How to fill out System Specs for tenforums.

I did notice you are using mismatched memory modules though, that may be a possible cause for some of your problems. BANK0 looks to be different than what is in BANK1, 2 and 3. As a test, remove what is in BANK0 (the mismatched DIMM) and BANK2 so you have 8GB in BANKS 1 and 3. Run and test, see what that shows you.
If better then replace the BANK0 DIMM with another that is the same as what was in BANK1, 2 and 3, which is like the following on Ebay:
