HELP Extremely Long boot times after installing new GPU

[Dan280599]

I recently upgraded from a 970 to a 5600 xt red dragon and after doing so I am facing boot times of almost 2 minutes compared to the 10 - 15 seconds I had before. I have removed all the old nvidia drivers, installed the new amd drivers, the card is flashed to the latest bios and so it my motherboard. Before i installed the gpu I could boot up in 15 seconds but now it takes ages and stays on the post screen for ages before finally loading into windows. I have tried with both ultra fast boot and launch CSM on and off but still there is not difference. Anyone know what's going on?

I can't see an options under csm related to the gpu. Also when ultra fast boot is enabled it removes the CSM tab completely so i asssume it sets everything to the fastest possible boot option autmatically. Still huge loading times regardless of what settings are on or off.
