CPU usaged at 99%

[a_robinson]

Hello everyone,

I have a computer I am working on for my company that the CPU goes up to 99-100% usage within a minute of logging into the PC. It was upgraded to Windows 10 but I di a factory reset of the machine thinking that the problem was the result of a stubborn virus I could not remove. That does not seem to be the problem however as the reset did not fix the laptop. The machine is now running Windows 8.1. What is wierd and has thrown me off is that the CPU usage jumps between processes. Some will be at normal usage levels such as .8 usage or 1% usage. Then it will jump to 64% or something crazy such as that. It will then just go randomly through the processes jumping up to high amounts. If you end the process it will resume itself or duplicate itself. I have been fixing computers for 7 years now and have never had this issue, any help would be greatly appreciated.

Thanks

Hey there! @a_robinson, Thanks for stopping by the HP Support Forums!

I understand the CPU usage is very high on your PC.

Don't worry I'll try to help you out.

Did you make any hardware or software changes on your PC?

Please provide the product number of your laptop to assist you better.

As you mentioned while using your PC the CPU usage goes high to 99°F.

Try updating the BIOS and chipset driver on your PC and check if it helps.

You can try updating the drivers using HP support assistant.

Refer this article to know more information about using HP support assistant.

If the issue still persists after trying out the steps try the steps recommended below.

Try performing the following ts steps:
 
1 - Right-click on any open space on your computer's task bar.
 
2 -Select "Task Manager" and press "Enter."
 
3 -Select "View" from the Taskbar Manager's pull-down menu. If more than one computer is connected to your network, notice the graphs for all CPUs. Select "One Graph Per CPU." This will help determine which computers are using more processing time.
 
4 -Go to the "Applications" tab. Because this tab shows open programs in real time, you will be able to see exactly when a program has been opened and closed at the time that it occurs. Identify and close selected programs by highlighting each one separately and clicking on "End Task" to free up processing time. (Important: Make sure all work is saved prior to closing any programs.)
 
5 -Go to the "Processes" tab and view them, but do not delete any of them unless absolutely necessary. All of the hidden system processes and programs are listed here. (Note: See Warnings section.)
 
6 -Set your computer's cooling fan to "Auto." Next, slide the Processing Speed scale to "3-4." Slide the Cooling Method scale to the middle of the range. These settings will slow down the CPU when needed
 

Also, Hit Win Key + R
Type in “Regedit” and then hit Enter.
Go to ‘HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management’
Find ‘ClearPageFileAtShutDown’ and change its value to 1
Restart the computer

If the issue still persists try the steps recommended below.
