Question Radeon RX 480 won't boot windows

[Marvin121]

Hi,

I'm switching GPUs from GTX 1050ti to Radeon RX480 but when I boot the machine with the new GPU installed it black screens after bios.

So far I have tried
removing old nvidia drivers using DDU
resetting CMOS
updating BIOS
Remounting GPU

build details
Intel Core i7-9700 3 GHz 8-Core Processor
MSI Z390-A PRO ATX LGA1151 Motherboard
G.Skill Ripjaws V 16 GB (2 x 8 GB) DDR4-3200 CL16 Memory
MSI GAMING X Radeon RX 480 8 GB Video Card
Corsair CX600M 600 W 80+ Bronze Certified Semi-modular ATX Power Supply

Was this 480 WORKING ON THE PREVIOUS SYSTEM?
