Pc start but no display after change win 10 to win 7

[xhimi]

In my computer
I changed windows 10 to windows 7 because it seemed too tiring.
But I have a problem.
When I turn on the computer and while it is working, nothing appears on the screen.
I tried and put another hdd with the same windows as this one installed (windows 7), and again it does not show anything.
the computer is new, 1 month i bought it.

What have I done wrong, can anyone help me?
Thanks to everyone.

Are you using the windows 7 drivers?

ASRock > A320M-DGS

What graphics card are you using?

what graphics card are you using?

graphic card is integrated and does not have to know.
I believe that is amd.

What is the cpu?

You could use this:
Windows 7 Image Updater - SkyLake\KabyLake\CoffeLake\Ryzen Threadripper


If that doesn't work , then you will need a separate graphics card

Probably you need a graphics card. It doesn't have to be an expensive one. The photo is from another forum. He says everything works - but he is using a discrete graphics card.

But i cant enter in start menu ,i cant see nothing at screen.
The same happen and when i try with another hdd with windows 7 installed in.

People using win7 usually avoid the G cpu with built in graphics. They then use a separate graphics card.

I don't know if adding a graphics card will work with a G cpu, it might.


There are amdGPU drivers included in this:

Windows 7 Image Updater - SkyLake\KabyLake\CoffeLake\Ryzen Threadripper
