I just installed an AMD RX 9060 XT 16GB GPU to replace my old Nvidia GTX 980, but now my computer won't boot into Windows. I can access the BIOS by spamming F2, but the screen stays black when trying to boot normally. I used DDU to uninstall the previous drivers before the installation. My motherboard is an Asrock Z370 Gaming ITX, and I'm running an Intel Core i5 8600K with an EVGA Supernova Gold 550W power supply. I've checked the power cables and reseated the GPU, but nothing seems to work. Could it be a problem with the power supply, or is there something else I should check?

Have you thought about trying to boot into Linux? It could help troubleshoot whether the issue is with Windows or the GPU itself. Just a suggestion!
A 550W power supply should handle the 9060 XT just fine for regular usage. However, you might experience limitations during high-demand applications. Have you tried connecting to the integrated graphics and running DDU again to clean everything up?
I’ve done that, but it still won’t boot into Windows. I even installed the drivers while using the integrated graphics before switching back to the new GPU.
I doubt the power supply is the problem. It should be enough to power the 9060 XT. Just to be sure, try the old GPU again to confirm whether it’s an issue with the new GPU or something else that's gone wrong.
I can confirm the system boots into Windows without any problems using the old GPU.
But you mentioned that the old one works, right? So it's definitely something with the new installation.
Since you're still able to get into the BIOS, the power supply might not be the culprit. Have you used DDU in safe mode? If not, I'd suggest reinstalling the old GPU and running DDU again in safe mode. It’s worth trying again even if you've already done it before. If that doesn't work, a fresh install of Windows may be necessary.
I tried safe mode like you suggested, but no luck. I even attempted to install the AMD drivers through the integrated GPU, but I still can’t boot into Windows.
I completely agree, definitely worth a shot!

I haven't tried that. Do you think it's a good idea to use Linux for troubleshooting?
