The problem started a few months ago. Recently i had to erase everything in the hardisk, including the Toshiba Recovery partition (it wasn't working anyway) and installed Windows 10 Home.

Now the laptop only uses the Intel HD 4600 graphics card. The device manager shows randomly the AMD gpu ("show hidden devices" enabled) and, when it does, it is disabled by Windows because, according to the OS, it is "causing problems".

The weirdest thing is, also recently, when i start Windows, sometimes the network adapter gets disabled (obviously loosing my internet connection) and when this happens the AMD gpu gets enabled It's as if there is some kind of a conflict between these two components...

I already tried clean installations of the most recent graphics card drivers for the Intel and the AMD, also the original manufacturer ones.

Am i missing something?

Thank you in advance for any help
