I'm now using the windows insider build of 10166. Catalyst drivers 15.7 now installs without blue screen, but I'm still getting periodic screen freezes.
Still think its a driver issue. Also VSR support is now gone from CCC mysteriously.
Update mark III
I got VSR back by using the Display Driver Uninstaller and then cleanly re-installing 15.7
Still getting periodic lockups every 4~6 hours, usually while web browsing (Chrome or Edge) or gaming.
update Mark IV
So the lock-ups were due to "turbo core" being on in bios. Turned that garbage off and everything is stable again.
