Troubles with the BIOS

[LegendarySkip]

I have just build a new PC with a Gigabyte B650 Eagle AX and a Ryzen 5 7600x3D. After getting it all build I tested if everything runs fine. Then I wanted to update the BIOS, but when booting up again my mouse and keyboard stop working after a few seconds. It always random intervals until they stop, sometime instant, sometimes it takes a few seconds. I have tried using all the different USB Port, both the motherboard ones and the one at the front of the case. Might I accidentally changed something in the BIOS that make it funk out? Any Ideas to fix it? I have been trying to reset the BIOS to stock setting, but I cant reach it in time-

I checked all the visible connection, the motherboard LED is als constantly on Boot, not showing any problems with other components and everything shows up in the BIOs. At the beginning and from what I can see, now as well. The picture seems to freeze rather than the peripherals not work, as active numbers stand still as well. Could it be a CPU issue?
