PC Drivers & Software

[shirdal]

Hello.

I have a Lenovo Z51-70 laptop with Intel HD5500 and AMD R9 M375 graphic and windows 10. Recently my graphic driver on device manager after windows 10 update was disappeared. When I download and run auto detect Radeon™ Graphics, it says error 173. In device manager I haven't AMD driver and it shows only Intel HD. In BIOS the setting was on "switchable graphics". I even tried to install previous version of Adrenalin AMD from this site:

but still same error.

I changed my OS to windows 7 SP1 but the same error appeared. A technician updated BIOS version, it didn't help.

In device manager>system devices there is "PCI Express Root Complex" with no yellow exclamation mark.

Please help!!! Thank you.

This is where you select drivers for your laptop: https://www.amd.com/en/support

The Intel graphics driver must be the latest from Intel and installed before the AMD driver: https://downloadcenter.intel.com/

You have to set Windows Update to Pause/Delay the automatic driver installation

I have done these. But still not solved.
