CPU Question/Help

[Smokemeowt]

I've used this site's help for as long as I can remember but only now have I signed up. Basically, I have a bit of an issue that I can't seem to find help with. Forgive me in advance if there's another topic where the issue mirrors mine completely, I just can't bother to find it. So my CPU has been stuck at 100% usage for a few days now. Even when idle. I'm really stumped as to why, and I really would like to keep restoring windows as an absolute last resort. If anyone has any tips or suggestions, I'll truly be grateful. Off the bat let me list what I've already tried.

• Restarting Computer.
• Checking for and Installing any Windows Updates.
• Restoring to a Restore Point from days before this issue began occurring.
• Checked Ryzen Master Software & MSI Software & Installed updates for what had updates.
• Compressed Air on PSU/GPU Fans, CPU Fan I already cleaned a week ago. Reapplied new thermal paste, I did it properly so that isn't the cause.

I'll list my specs too because I figure any bit helps.

• Motherboard: B350M Pro-VDH
• GPU: MSI GTX 1070 ti
• CPU: AMD Ryzen 5 2600x

I'm pretty sure those are the only things that matter, if you need anymore that could help, let me know. Also, if you need any other screenshots, let me know too. I'll attach the task manager image as well as my CPU-Z image.

If you can even suggest something that could diagnose it for me without having to reinstall windows, that'd be lovely as well. But thank you so much in advance for anything, honestly at this point anything helps.

 

Edit: Also, no I've never overclocked the CPU. I don't know if it came overclocked, but I personally never messed with it. I did attach a bit more detailed images so you can tell me hopefully.

Most common reason would be a virus or malware. Go download Malwarebytes and run a scan.

Went ahead and tried the scan, found nothing at all. Ran Windows Defender too, still nothing. Any other ideas?

Also, will constant 100% Utilization cause any issues? Thanks again in advance !

[Skiiwee29]

did you do a full scan?

[Smokemeowt]

Full/Deep scan, same thing right? Just yesterday I ran a scan with Windows Defender.
If by Full scan, you mean enable all scan options, then yeah I did that. I can't be bothered to pay for Malwarebytes premium. But this is how I setup the scan, and yeah aside from a couple PUP's which I got rid of, restarted, and still having the problem.

Still stuck at 100%. I've been able to play Modern Warfare, Minecraft, & Monster Hunter World all without stuttering. Could the percentage thing be broken? 

[Smokemeowt]

Okay now it's getting stutters during gameplay. Is there a software or something that will break down the CPU Utilization for you so you see exactly why it's maxed out? Thanks in advance.

[Smokemeowt]

Still have no clue why, been over 2 1/2 weeks, constantly at 100% Utilization. No fluctuation, just a constant 100%.
Currently at 130 Fahrenheit, that's not bad is it?
