Monitor causing bsod

[Ramasser]

Hi
I recently got a new Dell 27" qhd monitor and shortly after plugging in the monitor I'm getting the bsod screen during boot. I am unable to start in safe mode(still bsod, restore to a previous point(fails to restore) or use another monitor (it also will bsod). It crashes before log in screen. What's worse is a tried to use the monitor on my old computer and now I'm getting the bsod on that one...
Any help would be greatly appreciated, thanks!

What error code(s) do you get?

Does any BSOD occur when the new monitor isn't connected?
