Which T420s drivers are most stable? Old or new?

Which drivers to you tend to run on your T420s? Are the newer ones more or less stable?

 

I ask because with all the latest drivers installed (Lenovo website) on a fresh Windows 7 64 bit install, I get BSODs.


For example, I am having an issue where the latest synaptics driver (16.2.19.14, Rev 01, Date:  2014/08/11) is giving me a BSOD (0x000007E) in Win 7 x64 while running driver verifier on immediate startup.

 

If I uninstall this driver, the BSOD doesn't occur.

 

I seem to remember using drivers around the late 2012-early 2013 period without any issue, but it seems drivers which have been automatically updated by Lenovo system update throughout 2013 and 2014 have caused instead of mitigated system instability.

 

If you also look at the driver update release notes, it doesn't seem any fixes were added for the T420s, only new machine compatibility, and windows 8 compatibility. This tends to make me believe these drivers have not contributed anything new, but only complicated things.
