ive tried  few solutions for this problem like viewing which task or services use alot of cpu but nothing seems to work

Answer 1

I had the same problem as you. Any process or activity going on my computer raised the disk, CPU or Ethernet usage (depending on the activity) up to 100% and fans going crazy. Checked for trojans or virus and windows defender found win32/Tigger!rfn but couldn't get rid of it. Installed every malware and antivirus software you can imagine, no one solved the problem. Formatted the disks, installed windows many times and no joy.

Now it seems it is pretty much ok:

• formatted disks
• installed windows 10
• installed every single update
• decreased top processor usage to 80% on energy options

Somehow looks like working ok but I am not totally sure the trojan is clean.

I send a message to HP support so they can help me on that so the desktop is new.

I am now afraid to insert again the boot usb which I think could be infected also, better not to touch too much now.

Cheers!

Hello, 

To fix high CPU usage issue, please refer these steps: 

Try to identify the process creating this issue. 

Download Process Explorer from Microsoft: 

https://docs.microsoft.com/en-us/sysinternals/downloads/process-explorer 

Run the tool then select the system process, right-click and select Properties. 

Switch to the Threads tab. This will show which file is using the excessive CPU usage, from which you can then attempt to diagnose it.

Hi khalidenoaman,

I understand you are having a CPU usage 100% when you did an upgrade from Windows 7 to Windows 10.

I had experience this before and fix it temporarily but I was ended to do a clean installation.

The reaosn why, since there will be several issues especially hardware configuration are designed orinigall base from the Windows 7 system.

YOu may disable things but it's a total different if you'll do a clean instalation instead.
