CPU 100%

[luisken]

I've had an Intel(R) Celeron(R) N4020 laptop with a 1.10 GHz CPU and 4 GB of RAM for quite some time. To be clear, I'm writing here because I can't find any helpful solutions. This laptop worked fine before, and I was able to use it with Windows 10 and 11. The problem is that the CPU usage jumps from 0 to 100% in a second. As a last resort, I tried installing a version of MiniOS, which, of course, didn't work. I can't use any programs on it, because when I click on the desktop, everything flickers and is unusable. I've attached a video and image of my problem. Thank you for your attention.

Hello luisken,

Thank you for raising this concern via the Intel Community.

To properly investigate the issue, I would like to gather some information about your laptop so I can provide the appropriate troubleshooting steps and help isolate the problem.

Please provide the details below:

• What is the exact make and model of your laptop?
• When did the issue start occurring?
• When the CPU usage jumps from 0–100%, is the system idle at that time?
• What graphics driver version is currently installed?

Once I have the information above, I will be able to provide additional troubleshooting steps. If possible, please also attach a video of the laptop while the screen is flickering, as this would greatly help with the investigation.

Thank you, and I look forward to your response.

Regards,
