Whenever the graphics driver restarts "online" (like it does when you enable SLI, or when you update your driver), my PC BSODs. It shows the green GPU logo, screen goes black, then BSOD.

I have 2x GeForce GTX 560 Ti. They have worked in SLI in the past.

I've tried driver versions 331.93 and 331.65. I managed to update the driver by booting into safe mode (where it doesn't need to actively restart the driver). The new one still has this issue.

Gonna try to roll back to a significantly older driver.

I tried booting with each of the cards installed by themselves, they both work fine.

I'm on Windows 7 64-bit.

Solution
does the system start with both cards in the system but the sli bridge removed?

test the system with both card in but without an sli bridge and connect them to 2 different displays, try running 2 different 3d apps on each display, could be the power supply being unable to feed enought power to both cards anymore, or try a different psu if you have one to hand.
grab driver fusion from treexy and ccleaner.

uninstall the current driver and dont restart.
run driver fusion and run the nvidia driver cleaner then let it restart.
run the physx cleaner after restart aswell, should not need a restart but do it if it does.
run ccleaner file cleaner then run the registry cleaner multiple time till it finds no errors.
install the latest nvidia drivers and only install the display driver and control panel as a custom install.

see if the problem continues.

Well, before you posted your reply, I booted into Safe Mode to change my drivers one more time. This time I used an older driver version, 327.23.

With this version (and one previous, older version I tested, version 326.41), I AM able to enable SLI in the options, and I'm able to install different driver versions that do an online restart without a problem.

However when I try to load a game with SLI enabled, the game crashes to desktop. This is any game (tried AC4, World of Warplanes, BF3, PoE). Doesn't matter what SLI mode. Happens on both of the driver versions.
