CPU Usage running almost 100% - What is going on?

@Budgie2 It should… Have you updated the system BIOS at all?

Yes but a while ago. Where is best place to check or should I just start windows and use HP tool. As I recall I had to fetch the updates and download them and the HP tool then applied the update but it was several years ago when I installed the nvme. The HP website suggests I should update my bios as previous one was 2018 and there is a 2022 version. Will do it now.

@Budgie2 You can do it with the bin file on a USB device, boot to windows, or use linux and hp-flash…
