After Sept 01 update - OS X El Capitan, everything is pretty much non-responsive

Initially after restore, my first login it seems fine. I switch users and it never completes the setup. I hard power it off, then I'm able to login to the other account. I removed the samsung Kies software my wife uses for her phone since I saw others mention issues with it. Notice, not new update has been applied though. Then I switch back to my account and it starts behaving badly again, even without update.... so I booted back into safe mode, downloaded/ran etrecheck, but I'm not sure it's going to show anything useful unless I run it after normal boot up. Thoughts?

EDIT: here is the report from EtreCheck in safe mode

I did a lot of testing yesterday without much luck. A coworker of mine who is a good bit more OS X savvy than me suggested I restore to a point prior to the last update, mv ~/Library/Preferences/com.apple.systemuiserver.plist ~/Library/Preferences/com.apple.systemuiserver.plistbackup, reboot MAC, then re-install latest update. Prior to that, I once again got rid of the Kies Samsung software, reverted back to the default OS X driver for nvidia, then did the above instructions. So far so good...keeping my fingers crossed.

Thanks again Barney. I thought I was free and clear until the Nvidia Web Driver popped up with an update. Soon as I applied/restarted....it came back. I've posted this to the Nvidia forums for awareness:

After putting the latest OS X security update on my iMac, everything seemed to be working fine until I received the last update from NVIDIA. None of my startup/apps would come up, they just hung. I couldn't even bring up a console/terminal window to investigate further. At first, I didn't realize what was causing my issue and proceeded to restore, re-update, and have it happen all over again. After last restore, everything was working fine and I thought I had figured out my issue (Samsung Kies). However, the NVIDIA Web Driver notified me of a new update I hadn't installed yet. Soon as I did the update/restart, my problem was back. I couldn't start the NVIDIA Driver Manager to switch back. I was only able to switch back to the OS X default NVIDIA driver after booting into safe mode and re-installing (note: it would not run in safe mode either until I re-installed). Also, I did try re-installing in safe mode and rebooting without switching from the NVIDIA Web Driver and the problem still existed. Here's my info
