[SOLVED] 2700x is at 100% cpu usage while idle

[rohrbachryan2016]

I built this computer to use it to stream so when I finished it I installed the necessary drivers and then I started streaming and everything worked fine and after I finished streaming I decided to download all of the extra Utilities that come with the motherboard (MSI B450M Bazooka) and everything was fine when I shut down the pc at the end of the night. Today I started the computer and the cpu (Ryzen 2700X) was at 99% cpu usage and task manager didn't show any certain program as being the issue. If I tried to start the stream or even open too many tabs on chrome the computer would freeze. I kept trying to restart and troubleshoot to find the issue. I uninstalled all of the utilities to see if that was the issue and when that didn't work I just did a fresh install of windows again to see if that would fix the problem but after all that I'm still encountering issues. I've looked at videos and even forum posts here and I couldn't seen to figure out the issue.

I have done no overclocking to the cpu but it says that it is running at 4.0 GHz, even when i tried to set it back to stock in the bios it is still at 4.0. Idk if that may be contribruting the the issue but I thought I would add that in here also.

Once in Win10, reboot to safe mode and see what the CPU usage results are. If no joy, try the other two ways to enter safe mode.

I tried that and it didnt work task manager said that cpu was at 100% all times

Since you did a clean install if the OS, I guess we can assume you don't have some nasty malware running in the background. I couldn't see your entire processes obviously. But you said there was nothing heavy was running other than the the desktop window manager. But...
33% for the desktop window manager is way too much itself. Mine idles around 0.3 - 1.1%. So I'm curious about that alone. Did you have a bunch of windows open?

Nope this is it nothing open but taskmanager and gyazo to take the screenshot https://gyazo.com/5187fc14c877a42bd4a5b19f7f971089 Is there a way that ryzen master and taskmanager are bugged because ryzen master says my cpu is at like 90 degrees Celsius and if I were to go into bios it would say that its at 30 degrees celsius.

Ah. That is interesting. Normal temp in BIOS and high temp in Windows (just like you'd expect if the CPU were at 100% usage for an extended period)
I wonder if you acquired some kind of boot sector virus/rootkit before the clean install. Do this:

First run Malwarebytes. Be sure rootkits are selected in settings/protection. If good...
Run the Windows Defender Offline Scan and see if it finds anything.

I ran malwarebytes and it said I had no viruses and when I ran windows defender offline scan it didn't say anything so I'm assuming that it didn't find anything either.

Let's try a different approach. I realize you did a clean install of Win10. But if there's a virus hidden too deep for Defender and Malwarebytes to find, temporarily replacing the drive may be the only way to find out short of taking the system to a professional.

Do you have any old HDD or SSD laying around you can use? A friend's maybe? Might even consider a cheap small used drive on ebay. All we want it for is a quick W10 install to see if the issue is gone.

Btw, Did you make any changes in BIOS from default?

I am currently wiping the drive completely and im going to give it a fresh install with a different iso file to see if that solves any issues, if that dosent work I can take my main ssd from my gaming pc and see if works.

 

[rohrbachryan2016]

I wiped the drive completely and reinstalled with a fresh iso file and cpu usage is at 2% idle I'm praying that that was the fix because when i first installed it was like this and the next day it went to 100% so I will update this tomorrow if something goes wrong. Thanks for all your help I appreciate it @clutchc

Got my fingers crossed for ya
What did you use to wipe the drive? SSD?

I had the same issue. What worked for me was going to Start > Settings > Additional Power Settings. Mine was set for "Ultimate Performance", I changed that to "Balanced" and all was normal usage percentagewise. I also had an option for "AMD Ryzen Balanced", but that would peg it at 100% as well. I don't think this is an issue for me as temps seem fine and everything still runs snappy.
