Thanks Pauly! I tried that already and it still didn't work. Good news though, maybe. I found a post where someone modified an inf file in the driver for 314.22 which allows it to be installed for an Nvidia gtx 780. I followed the instructions and it surprisingly allowed me to install.

I must say, it seems MUCH more stable. I have been rendering several images for about 5 hours so far and it seemed to have resolved many issues!

-No more "Nvidia display driver stopped and recovered"
-No more monitor shutting off
-No more computer becoming unresponsive
-No more 0x000000C5

I pray that it stays like this and I didn't just get really lucky. I don't want to mark this as resolved YET, but I will check in soon to let you know if it kept working stable.

For any of those who are struggling with this, which I know many are, try doing this:
