Require additional support for CPU performance at full capacity.
Require additional support for CPU performance at full capacity.
A few months back I shared my experience with CPU operating at full capacity, and I require additional assistance since it continues to occur. Here are some unusual signs I’ve noticed: Tasks consuming all CPU power appear random, shifting between 5 to 10 processes each taking 40% to 10%. Terminating a demanding process leaves the workload shifted to another, which usually doesn’t improve performance. Adjusting the power plan helped temporarily—balanced plan reduced usage but performance plan worked well. However, this fix is not permanent; yesterday it was only the Ryzen balanced plan that caused the problem, now standard balanced is also causing it. I can restore settings via "restore default settings" on the balanced plan, and the CPU behaves normally for a short time, but then it returns to 100% within about 15 minutes, even when nothing appears to be wrong. The temperature rises too, and voltage spikes from 2.2GHz to 4GHz while the speed remains unchanged. When the CPU hits full load, performance doesn’t noticeably drop. I’ve reinstalled Windows fresh, but weeks or months later it starts acting again. Only official games and apps (like MS Office) are installed. I purchased Bitdefender and ran a 16-hour scan of all files and drives—no issues detected. I don’t use IE; I’ve used Opera, Chrome, and Firefox occasionally, and still experience this. I rely on built-in adblockers and block cookies unless added to a permission list. Anyone know if there are tools to investigate this recurring issue? Thanks, Stuart
I included the YouTube clip of the problem. I uploaded a complete full-length video, which makes it unclear why 360P remains the sole choice. I’m hoping it’s just still in the encoding process.
It looks like Opera Browser was the culprit behind the performance issues. When I opened it, it seemed to overload the system by consuming 100% CPU, even after closing and restarting. Resetting the power plan back to defaults fixed the problem, but whenever Opera was active, it still caused excessive usage. After uninstalling Opera completely—deleting all related files and folders—I regained normal CPU performance. The Ryzen power plan still causes the issue, as it lacks a default reset option. I’m curious if these settings are saved in the registry. Also, did the options shown in the power plan interface change after reinstalling Firefox? P.S. I’ve switched to Firefox now.
Power plans doesn't address your issue. As shown in the video you shared, the CPU is constantly reaching 100% (possibly due to a virus, faulty drivers, or system failure). In this case, even a powerful computer can become overwhelmed. Reinstall Windows. The CPU should ideally stay under 1% even when using power-saving mode. Monitor CPU usage after each software installation and you'll identify the culprit.
1) Take off internet connection – if traffic drops, it’s likely malware or a virus operating silently on your network.
2) Perform a clean boot – if everything works fine, restart and turn on services one by one to identify the offender.
3) Adjust security settings for programs with heavy CPU usage, blocking them for all users under their properties.
