I've been in contact with dell support regarding this but they can't solve it and they now want to replace my motherboard (which I don't think is the issue here).
When i got the laptop all drivers were installed and worked just great, then I got a hdd replacement and dell wanted me to reinstall windows to verify some stuff (not important here).
I managed to install all drivers but the Intel UHD 630 one.
I've tried to install the one that I can download from dell and several other versions directly from Intel download center... but none will work.

Just made a clean install of windows again and then tried to install the driver again, but no luck.
The two drivers I tried to install now was:
Intel-UHD-Graphics-630-Driver_666TW_WIN_220.127.116.1173_A01 (from dell's website)
And "win64_18.104.22.16860" an older one form Intel's website.
On the last mentioned driver (win64_22.214.171.12460) I got another error message though.
Please can someone explain to me how to install this driver?
The motherboard replacement doesn't feel like a solution, but dell has sent out a technician that will replace it tomorrow because that was their only solution for this.
