Üdvözlöm Laura_Me!
Csak tájékoztatni szeretnélek, hogy mire jutottam. A Te leírásod alapján nem jutottam előbbre.
Az interneten kicsit kutakodtam és ezt találtam:
I found the solution in an older topic. I could not believe it works. Now I know where the problem is.
!!! LATEST VERSION INTEL VIDEO DRIVER (10.18.10.3308, A01) NOT WORKS WITH LATEST AMD DRIVER (13.151.0.0, A00) - THIS IS A PROBLEM FOR WHICH HD8850M DOES NOT WORK!!!!
Here is my modified instructions from Perrygogas:
- Upgrade BIOS to A06.
- Download (do not install yet) the drivers for Windows 8.1 from DELL's site (not from the manufacturers) for Chipset x 2 and Display x 2. These are the ones in the attached image. All drivers are the latest version expect for Intel video driver - you must download PREVIOUS VERSION (10.18.10.3277,A00), which works perfectly.
- Uninstall Intel video driver and all AMD Catalyst software. You can use "Display Driver Uninstaller" in SAFE MODE - it is really good, simple and free program.
- Restart Notebook.
5. Install all drivers EXCEPT the one for VIDEO_AMD - the first one in the image above.
- Restart Notebook.
- Check if the AMD device is still uninstalled (in Programs and Features) if not go to step 3.
- Install the driver "Video_AMD....". This is the driver for AMD Radeon 8800M and above the first one in the image.
- Restart Notebook.
- AMD graphic should works now.
Hát ezt megcsináltam és lőn működik a rendszer!
