Centos 7 Kernel Error EDAC: Could not find mci handler

Have a fresh Centos 7 + MATE install on a 1TB SSD.
Everything WAS working fine.
Not sure if this is the cause but was tweaking the BIOS(Asus X99A2) attempting a firmware update and the next time I tried booting into Linux my screen freezes with the 3 following lines

EDAC sbridge: ECC is disabled. Aborting
EDAC sbridge: Couldn't find mci handler
kvm: disabled by bios
[sdb] No Caching mode page found
[sdb] Assuming drive cache: write through
I've googled quite a bit and found similar errors(this following link is for an Ubuntu install)

but no definitive answers!

Pretty sure the first line regarding ECC is bogus since my MOBO doesn't support ECC RAM anyways.
I'm confused as to whether this is a BIOS setting error or a Linux install error. I went ahead and made sure my BIOS was properly updated but still get the same error.
I'd like to avoid having to reformat my SSD and reinstall everything from scratch!

I'm pretty well stuck and am hoping someone has a solution.
Any feedback welcome. Thanks!

issue (I believe) had to do with Nvidia drivers

Solved (I think, at least is working so far) by uninstalling, then rebooting and reinstalling from elrepo using yum install kmod-nvidia
