BSOD - many times in recent months

Edit: Post slowly. And keep a cool head.

All the verifier enabled crash dumps are pointing to the display driver, the latest version. It fails.

Disable Driver Verifier for the time being.

DRIVER_VERIFIER_DETECTED_VIOLATION (c4)
A device driver attempting to corrupt the system has been caught.  This is
because the driver was specified in the registry as being suspect (by the
administrator) and the kernel has enabled substantial checking of this driver.
If the driver attempts to corrupt the system, bugchecks 0xC4, 0xC1 and 0xA will
be among the most commonly seen crashes.
Arguments:
Arg1: 00000000000000f6, Referencing user handle as KernelMode.
Arg2: 0000000000000188, Handle value being referenced.
Arg3: fffffa800caa5060, Address of the current process.
Arg4: fffff8800f4df0a1, Address inside the driver that is performing the incorrect reference.

You cannot uninstall all at once.

Accept all offered restarts.

Hey Arc, just wondering - your reply earlier didn't say anything about uninstalling Geforce Experience, I've got Geforce Experience 1.8.2 still, and when I uninstalled Virtual Audio 1.2.20, it told me to restart, I restarted and it reinstalled itself on reboot, I did that two more times and it did the same thing so I couldn't uninstall it.

Right now I've got:
Geforce Experience 1.8.2
Graphics Driver 332.21
PhysX System Software 9.13.0725
Virtual Audio 1.2.20

What do I do now?

Edit: Sorry - doing the DDU thing, skipped a step, will be done soon!

Edit: Just completed it - I now don't have Geforce Experience? :s Is that supposed to happen?

Yes, you pointed a good thing there .... the GeForce experience is also to be uninstalled.

Yes, uninstall them two.

Then install the suggested one, the graphics driver and PhysX only.
