Question CPU maxing out around 0.40 GHz

[paddyvipond]

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

Welcome to the forums, newcomer!

Can you get into BIOS and see if your processor's clock speeds are as they should be? If so, then the issue is your OS. Can you check and see if your laptop is pending any BIOS updates?

I have tried a factory reset
I doubt it but perhaps the laptop might need an RMA if a BIOS update/OS reinstall doesn't alleviate the issue. Recreate your bootable USB installer for Windows 11, backup all mission critical information, then reinstall the OS in offline mode;

Once complete, install all drivers in an elevated command.

Post a screenshot of the ThrottleStop Limit Reasons window. I am guessing that your computer has a BD PROCHOT throttling problem. This is the most likely reason your CPU is stuck at its minimum speed. One bad sensor on the motherboard or elsewhere can cause this.
