Question AMD Ryzen 5600X3D showing 100% usage with no load.

[TacticalSloth]

So I recently noticed that my CPU is running at 100% and there is no load on the CPU. I did a completed reinstall of Windows and ran a virus/ malware scan with no hits. When I start up Task Manager where it says CPU its originally white text and then after a few seconds it changes to black text. My PC runs fine but I don't want there to be an issue and do anything about it.

Full hardware specs and current motherboard BIOS version?

What is the current Windows power plan?

Where are you seeing that it says it's running at 100%?

Download HWinfo, install it, run it, choose "sensors only", then take screenshots of all the sensor values while the system is at least mostly idle. It may take several screenshots, scrolling down between pics to capture all the sensors. Upload the images to imgur or another image hosting site and use the direct link method to post images here.

Darkbreeze,

thank you for getting back to me. I couldn't get the direct link method to work. but I have the photos below and here is the link incase it doesn't work once I post it.

I current specs are
CPU: AMD Ryzen 7 5800X3D 8-Core
MOBO: MSI MAG B550 Tomahawk MOBO (haven't updated MOBO since I built my PC back in Jan of 2022) *Update I just updated my BIOS. still no change. *
RAM: G-Skill Ripjaws 8GBx4
ASUS KO 3060Ti
I am running Windows 11.

Power Plan is currently running High Performance. I have messed around with this to see if it was causing my issue but it didn't change anything.

I'll try to look at this tomorrow. Today was more trying than I could explain. Long day. I will look at it soon as I can though.

Thank you Darkbreeze. I did find another form from Microsoft and I think it might be a messed up file within my windows OS. I am gonna attempt to do a full clean install and see if that fixes the issue. and let you know

 

[Darkbreeze]

Yeah, I think a clean install is a good idea, and then, as you begin adding programs back in (After running through all available Windows updates and installing all recommended drivers from AMD and your motherboard's product support page for chipset (Get this from the AMD website), network adapters, audio controller, Bluetooth (If equipped), etc.) take the time between each program installation to take a look at whether it's back to using 100% core utilization again because you might just find that it's something you have installed that is causing this.

 

[punkncat]

Have you pulled up Task Manager/Processes to see what is actually causing that usage?

If you hadn't said you have already clean installed I would immediately say virus or other malware.

Did you get your install USB from a known uninfected machine, directly from Microsoft? Didn't use "Rufus" or any of that?

 

[Darkbreeze]

There is a task manager screenshot in the ones he linked to but it's only a small section and isn't sorted to bring the highest CPU use processes to the top, which would I agree have been helpful but at this point I am of the opinion that since I can already see there are things installed that I'd probably tell a person "ehhhhhhhhhhhhh" maybe don't be installing that anymore, it would make a lot of sense to simply do a clean install, and then before installing ANYTHING else after doing all the Windows updates and drivers, check to see if it is still at 100%, because if it is at that point then it almost has to be either a hardware issue OR as you suggested, possibly an infected installer.

I 100% agree that it would be a very good idea to create the installer using the media creation tool on a totally different machine that is for sure not infected and working properly, just to eliminate that possibility.

Darkbreeze,

the clean install fixed the issue. thank you for helping out.

 

[Darkbreeze]

Fantastic man. Glad you got it sorted out.
