Question CPU maxing out around 0.40 GHz

Hey folks,

(I assume this is the right place to drop this question, but apologies if not)

I have been suffering with this problem a few weeks now and cannot find an explanation or a solution. A "techy" friend on TeamViewer was unable to, as was my local laptop repair shop.

My laptop has been almost unusable for a few weeks now, unable to open multiple tabs, run multiple programs, and impossible to take video calls over Teams/Zoom/GoogleMeets/etc.

My CPU is also running very low. It rarely climbs above 10% and when I really need it to do things (load pages, download, open programs), it runs even slower. It seems to be self-limiting to 0.4GHz and won't budge from there, meaning everything I try and work on is in slow motion.

It makes no difference if the laptop is plugged in or not, I have changed the Min power settings, I have ensured nothing is on battery saver, I have downloaded all the latest updates from both Windows and Samsung, and most recently I have tried a factory reset and that hasn't fixed it. I have a Samsung laptop running Windows 11.

I did a diagnostics of my machine and this is what I got back: https://userdiag.com/id/HA8G3EE8eB
The graphics and graphics driver are highlighted as an obvious problem, but if you look at the Processor, you can see the "self-limiting" that my machine seems to be resorting to as well.

I'd really appreciate some help and advice on this, as I really don't know what to do.

Thanks
