maybe need to apply thermal paste?
Maybe stop downloading 4k Porn
Just as others suggested here, a clean reinstall of windows will help, just keep your files and programs like discord, steam, teamspeak and get rid of everything else, this will also boost fps ^^ (at least it did for me) and your computer will speed up, you can easily factory reset your PC with windows 10, its in the settings!
scan your pc with malwarebytes lol
Ive had a lot of issues with my i5 7400 running at super high %
So i just installed a new cpu and now all is good
Replacing your CPU seems quite extreme to begin with...
What else are the in your computer? Disks, RAM?
If those are the percentages while idling, they seem quite high, for all three categories.
Could be malware, could be just a corrupt setting.
Should at least try a clean install before replacing your CPU.
Could be anything, Windows has a ton of issues. My GPU was overheating and my Windows was freezing. You know what the problem was? A broken SATA driver. Yeah. So, the best bet would just type in the exact issues you are having into a search engine and read around for a fix.
1- virus scan
2- check thermal paste
3- check airflow
4- dont listen to retards saying reinstall windows lol
5- backup and format c:\
It looks like a Malware or Bitcoin miner. Just scan with Malwarebytes
Nothing wrong with your CPU. That 100% disk looks like what you should be focusing on.
what programm takes all the resources?
