I recently upgraded my PC with an Intel Arc B580 GPU, and initially, it worked fine. I installed the necessary drivers and was getting video output. However, upon rebooting, the screen would go black, forcing me to shut down and restart to get a signal again. To troubleshoot, I made some changes in the BIOS by disabling Fast Boot, CSM, and the integrated graphics of my CPU. After saving those changes and rebooting, I ended up with a completely black screen with no video at all, not even the BIOS display. I reset the BIOS by removing the motherboard battery, thinking I had messed something up, but it's still not giving any video output. The GPU fans spin for a few seconds on startup and feel warm, suggesting it's receiving power, but it doesn't show up in Windows Device Manager. I can use integrated graphics just fine, but I'm worried about my new GPU, especially since it's hard to replace from my location due to high costs. Any suggestions or solutions would be greatly appreciated!

Have you enabled ReBAR in your BIOS? It could make a difference. Sometimes, even if it showed as disabled in Intel's software, you might need it on for the GPU to function properly. Just a thought!
Have you checked if the GPU is seated properly? Sometimes it's as simple as removing it and putting it back in. Also, ensure it's plugged directly into the motherboard and not through a riser if you're using one. Good luck!
Yeah, it's connected directly to the motherboard. I tried reseating it, but I'm still getting no video.
I did enable 4G Decoding and Resizable BAR. It showed disabled at first, but even when it was working, it still gave me video. Now, though, I'm getting nothing at all.
