Lenovo G500 - AMD Radeon HD8570M black screen graphics problem

Hello,
Yesterday I bought Windows 10 Pro x64 Bit and installed it on Legacy support because on uefi it did not detect the board with the system, but to the point.
I have 2 graphics cards in my laptop. one integre intel hd graphics 4000 and installing its drivers was not a problem, I downloaded from intel and it works.
The problem is with the second AMD Radeon HD8750M card, I downloaded the drivers for it (in bios I had Switchable graphics selected) and when it wrote: Installation AMD screen driver the image stuck (frozen) and it helped to remove the battery and disconnect from the power supply. Then when I started the system, the logo appeared Lenovo, then the windows loading screen and when it loaded there was a black screen, nothing could be done but I was able to start the system when I changed from Switchable graphics to Uma graphics (It's only an integra). I will add that I had windows 7 on this computer yesterday ultimate and there was no problem with installing drivers for Amd and Intel everything worked. Please help.

I had the same problem on the lenovo g510. For me it was not the fault of the system or the laptop. The fault was in the graphics card drivers. Uninstall the latest ones and install the older versions. I had a bug in these Crimson drivers.

Well, but how do I install as soon as I change from Uma to Switchable, a black screen, nothing can be done if you want, I can even record a movie

If the computer works on uma try system recovery, but I don't know how it turns on in 10. It should go back to the state it was before installing the controls and work properly. I've been struggling with a similar problem for a few days in wines 8.1 and the AMD drivers are definitely to blame - nothing ever suits them. Try to update the AMD driver from the device manager, this is the only option that works for me.

Okay I coped with the DDU program uninstalled all the drivers and the guitar. How do I install from the manager level?

Search in the control panel for device manager - graphic cards - choose which one you are interested in - driver - update the driver. At least that's the way it is for me, I didn't work for 10 but I suspect it will be the same.

The problem is solved, I managed it myself
1. Uninstalling the drivers from the DDU integrated (if you have the amd driver, also uninstall the DDU)
2.Restart the PC
3.install the old driver for the AMD card (with 2K14)
4.Restart the PC
5. installing the driver for the integrated
6.Restart the PC
