B650M PG Riptide No UEFI/POST

Hello, so, I recently upgraded to ryzen 7600x using the b650m pg riptide motherboard. During boot, I get no video output during the splash screen and no POST as a result. I tried booting into bios or at least get into the boot menu but no dice. The keyboard and mouse are responsive at that time.

I then took advantage of the flashback feature to update my bios, which did work (led was blinking at first, then it stopped blinking after some minutes, as per the guide thing). I still have the same problem. Updated every driver I could update, same issue. I am using HDMI (some people apparently had issues with displayport, but I'm not using any). I tried going from my GPU's (rtx 3070) port to the motherboard, still no output.

Other than that, the PC will boot into Windows 11 and operate normally. I tried using the restart into uefi utility but I did not have success as there was still no video output. I tried restarting while holding shift, it didn't work. I am at my wit's end, what else can I try?

Unless there is a way to disable the igpu with no video output, I can't do that. I guess I COULD do it blindly if I had a visual guide but it'd be risky.

I updated the bios to the latest version through the flashback. At least I think I did (I downloaded the latest version on the website and put that in the usb stick).

Checked the version I downloaded, it was indeed the one from yesterday. (1.14 AS15)

I tried both jumper reset and taking out the gpu. The end result was the same (it should be noted that I got no video output at all from the motherboard's hdmi port).

i have the same problem just got the board freiday 2023/03/03 and no post at all i used the old ssd with win 10 x64 from old setup and just let it run and it log in to windows. but cant get in to bios.
