Hello,
I have a Dell Vostro 3560 laptop including an Intel HD Graphics 4000 and an AMD Radeon HD 7670m graphic card (standard equipment, nothing's been added).
After updating to Windows 10 I manually installed the catalyst 15.7.1 driver and also deactivated Window's automatic graphic card driver update. Afterwads, the driver is visible in the Windows device manager (it shows 15.200.1062.1003 as driver version). However, if I deactivate my Intel HD Graphics 4000 graphic card, which is also part of the laptop, I get an error message by the Catalyst Control Center saying the driver is either broken or needs to be updated. My laptop then switches to Microsoft Basic Display Driver. I've repeated this procedure several times and checked on google for about four hours but nothing worked.
Do you have any idea what the problem could be?
