Unity 5 crashing immediately on start up

Hi All,

Just upgraded my system motherboard and processor and reinstalled Windows 7. Reinstalled Unity 5. Now when I launch Unity, it immediately crashes. It shows the splash screen, but doesn't get to the login screen. No log files are created.

Unity 5 v5.1.3.41531 System: Windows 7 (all patches/updates applied) Intel i5 4460 3.2 ghz Asus Z97k mb Asus 750 ti (driver 353.82)
