I've been tearing my hair out for weeks on this one. It's time to ask for help.

I've been running a successful dual boot 10.10.3 with Win 8.1 for about a year. One morning after switching from OSX to Win and back again I ran into a reboot loop on the OSX side. Everything is still 100% on Win 8.1, but I do all my productivity in OSX.
It won't boot with nvda_drv=1, reboot loops every time. The System can be booted with nv_disable=1, this seems to be the only stable way. Doesn't matter if I disable the 4600 or not. I can post to pci1, but not with the web drivers, and disabled only gives me one screen. This can be done with or without the 4600.
I'm running quad displays, 3 on the 970, one on the intel 4600.
After a bunch of tinkering, it definitely has something to do with loading the web drivers. Without thinking I ended up updating everything, everything seems to be working except the memory isn't reporting 100% and I can't use the 970. I did try multiple drivers, throughout 10.4 & 10.5 with security updates. Same issues.
Currently
OSX 10.10.5 14F1509
Web Driver 346.02.03f04
I feel like I've tried everything, but who knows I may have a typo somewhere I just can't see.
I can't find an answer after digging through the forums for a couple days. Hopefully someone knows how to fix this. I really don't want to work in Windows.
