Awkward behaviour - Bios restarts and stutters - Fedora 41

Hello I freshly switched from windows 11 to Fedora, I am amazed so far, although I miss some features. I use fedora some years ago already. For me it was the go to distro and haven’t really considered another distro. But these things (especially no.2) makes me thinking about going for another distro.

But I have some issues which a google search didn’t help me with.

  1. Everytime I hit reboot or the system reboots due to update my pc goes to Bios. In Windows this did not happen - what could be the reason.

  2. I sense small stutters, which is really awkward, My system has an AMD 8845HS 64GB of DDR5 Ram and a 2tb NVME Disk - I did all updates and installed also the chipset-driver via software center.

Do you have any ideas how I can solve this?

Best regards
