Hi hauser.markus
I Think Amd & Nvida are drivers that come with your graphic card if you have an Intel Processor,
these could be uninstalled without problems
Uninstalling the Intel drivers will give You problems and your screen probaby will be black and
probably your computer will not start
In an amd Processor the graphic card is integrated onto the processor,
You also will get into problems uninstalling them.
I Should use Driverbooster, it updates all intel drivers, graphic divers ,controllers,
system devices, visual C, Net Framework ,scanners, audio drvers etc,
So why uninstall them as You simply can update them easely to the newest drivers
