Unity crashes while building any project

I have already sumbitted this as a bug; along with the editor’s UI getting al deformed and messed up in DX11 mode. (yes I have checked my drivers etc)

I don’t get why with this new release Unity just crashes when building any project. Even an empty one made it crash. Anyone got any ideas?

(PS: these are my system specs and I have been able to build projects just fine on this machine)
Windows 7 64-bit
8Gb of RAM (recently upgraded from 4Gb though)
AMD Radeon HD 5670 (1Gb GDDR5)
AMD Phenom II X4 840 (3.20Ghz)

What does the editor log say? It’s impossible to give an suggestions when there is no data to look at. Also, what’s the bug number?

Here’s the one for the editor crashing:

And for the derped UI in DX11 mode:

Here are two logs from the Unity Editor:

Hmm, no real stack trace on the Editor.log, looks to be a graphics driver problem:

========== OUTPUTING STACK TRACE ==================
(0x59D29DFD) (S3DWrapperD3D9): (filename not available): D3DPERF_GetStatus + 0x919d
========== END OF STACKTRACE ===========

You seem to have a great way of making yourself popular with the QA guys who are going to take a look at this. Bear in mind the QA guys look at bug reports every single day of the year, so profanity won’t help you.

Eh, right sorry.
I tried installing the beta drivers and now compiling/building projects works, but DX11 mode still crashes the editor:

========== OUTPUTING STACK TRACE ==================

(0x11312702) (S3DWrapperD3D10): (filename not available): OpenAdapter10_2 + 0x19632

========== END OF STACKTRACE ===========

When I googled “S3DWrapperD3D10” I saw results from iz3D (a driver I might still have installed)
I’m going to try uninstalling iz3D and see if that fixes the issue.

EDIT:
Yup, uninstalling iz3D seems to have fixed it. Sorry for any inconvenience
