Switchable Graphics

[kasrah]

hi, I have a probook 4530s with windows 10(64bit).

my problem is with the switchable graphics. when I enable switchable graphics option in the BIOS( version: F65) I cannot install either of my video drivers. then I have to go to the safe mode and uninstall microsoft plug and play display driver and go back to BIOS and disable the switchable graphic and reboot and only then intel hd 3000 works.

I tried installing any version of AMD catalyst drivers and it failed during the  installation of AMD display driver( screen goes black for hours and nothing happens).

I tried to downgrade BIOS but it is not possible with new version.

with switchable graphics enabled I used GPU-Z and it detected both intel and radeon but it said that multi gpu and AMD crossfire are disabled.

Are you sure it has dual graphics ? The series does not have any model/product which supports dual graphics, only has

Integrated: Intel HD Graphics 3000 Intel HD Graphics for Celeron

Yes I had no problems for years and Radeon 6490 was working flawlessly then suddenly I got BSODs. 

I'm not sure if it is hardware issue or software.
