Black screen before logon in Windows 10

[RSabino3]

I recently upgraded my laptop Pavilion dv6-6047 cl from Windows 7 - 64 bit to Windows 10 - 64 bit. The only thing I changed from the original spec (see link below) was that I bought an Samsung SSD 850 EVO 500GB. In Windows 7 everything was fine, the boot used to take up to 8s. Now it boots, but stay for more than 1 minute stuck in a black screen before the logon screen appears.
I tried to update the graphic card driver, but nothing happened.

The processor driver is up to date.

The SSD driver is up to date too.

I rolled back to Windows 7 and everything went to normal again. And then upgraded to Windows 10 again, everything goes black again.
Please help me, because my SSD is worth nothing with a 1+ minute boot.

Thanks in advance!

I solved it! I disabled  ULPS following this http://www.tomshardware.co.uk/faq/id-1904869/disable-ulps-amd-crossfire-setups.html . Everything is fine now! It's booting fast again!

App readiness seemed to be my issue.
