illustrator freezes & task manager show cpu 100% for system interrupt.

How old is your notebook computer? Some of the specs listed, such as the NVidia MX920, would make it around 10 years old. The system may not have enough performance capability to run the current version of Illustrator.

Hi @waassta_9159,

Thanks for reaching out, and sorry to hear about the trouble you're facing. Could you please confirm the Illustrator version you're using along with the details of your Windows OS? As a first step, try resetting Illustrator preferences manually by following the steps in this HelpX article: https://adobe.ly/4sHAH7n. If that doesn't help, please test the issue in Windows Safe Mode to help isolate whether a third-party extension or plugin might be causing the behavior. Ref: https://adobe.ly/4bFhyNi

If the issue still persists, please check Task Manager and confirm whether the high CPU usage is coming from CEPHtmlEngine. If so, this article should help: https://adobe.ly/4bFhzAQ. You may also want to review a similar discussion covering the same behavior and try the suggestions shared there.

Please let me know how it goes, and I'll be happy to help further.
