Thanks for the answer. I have another Question. I reinstalled Windows 10 from scratch now. The display works because it takes the Windows basic display drivers. But as soon as I connect to internet Windows starts looking for new display drivers and installs it automatically in the background. And soon as this driver is install my screen goes blank/black. Is there a way to stop windows from installing this driver or to disable the graphics card?
I am ok with using with the basic display drivers. It is not as crisp as the AMD display drivers but it works and it doesn't go blank and I able to use my laptop for basic browsing and stuff.
