12500 / UHD 770 driver problems

[LeewaySpace]

Hey everyone, 

unfortunately i am loosing my mind. I bought 2 PCs for my business, excactly the same components, and cannot get the intel uhd graphics to work. Hardware Parts, see below.

Now i am stuck at a resolution of 800x600 after a fresh windows 10 install, i installed all motherboard drivers by CD, but i cannot get the internal graphics to work. 

The Intel Driver&Support Asissten gives me an unknown error (0x80070490) and cannot install the driver, if i download the driver manually and try to install it, nothing happens. 

Device Manager does not shows only the microsoft basic display adapter, although there ist a problem with a PCI simple communication controller, which i suspect to be the internal graphics. Hardware ID of that controller is:

PCI\VEN_8086&DEV_7AE8&SUBSYS_31181565&REV_11

PCI\VEN_8086&DEV_7AE8&SUBSYS_31181565

PCI\VEN_8086&DEV_7AE8&CC:078000

PCI\VEN_8086&DEV_7AE8&CC:0780

Installing the Intel Managment Software does not help either. Tried Displayport and HDMI, does not change anything. BIOS is up to date. Thing is that both completely identical PCs have the same problem. The 12500 i bought DOES have integrated graphics, but somehow i dont get it to work. If any of you can help me i would truly appreciate.
