Virus

Hi, I recently got a mining virus (cryptojacking). I changed nearly all the components of my PC yesterday and I think there are no more viruses on my computer because I completely reset everything. However, when I launch a game, my graphics card goes to 100% no matter the graphics settings. It seems like something is hiding that is using the capabilities of my graphics card. This is not the only problem; my C drive is always at 100% even though I got an SSD to help, but nothing is improving. Also, my processor is between 100% and 70%. When I open the task manager, it drops down to 2%, 3%, 5%. Thank you.
My config
GPU: RTX 3070
CPU: AMD Ryzen 5 3600
SSD: 440 GB
Hard drive: 1 TB (the one where I got the virus)

Hello,
What component did you change? Did you do a clean reinstall of Windows or did you just reset the existing Windows?
What is your version of Windows?
=> Press Windows + R
=> Type Winver and hit enter
=> Provide the second line => Version ****
Thank you for your response,
I have reset the 2 drives from the command line and reinstalled Windows with a USB key.
Windows version 10
Version 22H2 (Operating system build 19044.1889)
I reset the 2 disks from the commands
Isn't there a word missing? Which command?
Version 22H2 (Operating system build 19044,1889)
Rather 21H2, right?
If you have reinstalled everything properly (with partition deletion, I suppose?), there is no reason for there to be a virus

Let's start with a PC diagnosis:
Read the entire procedure carefully before posting the reports
Do not post them directly in the messages as they are unreadable and incomplete
The reports FRST.txt and Addition.txt are expected
All reports must be hosted on https://security-x.fr/up/ and you indicate the links obtained in your response
---------------------------------------------------------------------------------------------
--> The SmartScreen filter may trigger an alert. Click on Actions or More information and then on Run anyway
---------------------------------------------------------------------------------------------
--> Download the FRST version of Farbar, compatible with your system and save the file to your Desktop
--> For a 32-bit system
--> For a 64-bit system
How to find out whether my system is running 32-bit or 64-bit?
--> Wait until your browser offers you the download to save, without clicking anywhere, especially not on the sponsors of the page.
--> Close all applications, including your browser
--> Double-click on FRST.exe and click Yes to accept the Disclaimer
--> Under Vista, Windows 7 / 8 and 10, you need to run the file by right-clicking -> Run as administrator
--> Wait until it indicates The tool is ready to run
--> In the main menu, click on Scan and wait for the analysis to complete
--> At the end of the scan, the reports FRST.txt and Addition.txt are created. Post these reports in your next response.
--> The reports are saved in the same location as the tool and under C:\FRST\Logs

To reinstall Windows, I reset the PC from the settings but I interrupted the process by turning off the PC (because I don't know how else to do it). After that, I followed a video https://www.youtube.com/watch?v=Fsv0-YqGExo&t=254s which shows how to delete the hard drive and convert it from MBR to GPT, then the PC restarted normally except that the problem was still there.
I'm sorry, I tried everything to remove the virus.

No infection. The problem certainly comes from the way you reset Windows.
Your system is still in MBR and not in GPT.
Did you reinstall Steam and Epic, or were they already installed and not removed?
When I reinstalled the PC, only Edge was installed.
So there are no problems now, but why is my C drive at 100% when I'm not even using 1/3 of the space?
And why is my graphics card at 99% for most games, no matter the game, no matter the graphics settings, not to mention that it rises to 70°C during gameplay (I have 6 quality fans).
I'm really sorry to bother you with my problem, but this forum is my last resort.

Since it is not viral, create a new topic here => https://forums.commentcamarche.net/forum/carte-graphique-181, but for me, it certainly needs to be properly reinstalled in GPT
To automatically delete all files/folders created by FRST and the tool itself, rename FRST/FRST64.exe to uninstall.exe and run it. The process requires a restart
