I have the same computer and same configuration. I struggle to make graphics work correctly with windows 10 1703 and since my update in 1709, i m stuck again.
For your BSOD problem, the problem comes from he ULPS option (ultra low power state). If you disable it in the registrer (ENABLEULPS = 0) you will make the BSOD disapear. Note that each time you change your drivers, this option will be again turn to 1 (i personnaly turn the value to 0 during the installation)
Note that this doesn't solve the switchable graphics issue (make the 7730 to run when it is needed). Here are my notes of what was working on windows 10 1703 :
ULPS = 0
Options d'alimentation :
PCI express = disable
Intel = max perf
ATI = Max perf
Intel = 07/04/2017 (version win64_153345.4653)
ATI = 22/06/2015 (default windows 10 driver) Note that you need the amd control pannel to recognize your card for that to work
Good luck !
