Windows 10: Why does my CPU utilization go up whenever I use my mouse even though I am just watching...

My CPU utilization goes up whenever I move my mouse across the screen. I found the problem whenever I closed Fortnite. Whenever I start watching videos on YouTube whenever I move my mouse the whole video slows down and sometimes it even freezes which become annoying because I try to multitask but it just becomes harder than it needs to be. I also have a reason to believe that it is because of the new GPU that I recently installed in my computer which is an RX 580 8GB. I tried finding a solution, one of them being checking the software that the mouse that I use comes with Razer Synapse/ Razer

Insane cpu usage when watching streams/videos

Hi,

If you are seeing issues with playing online videos, it might be due to Internet Connections also. I would suggest you to check if you have any other issues with performance in Windows 10.



A high percentage means that the programs or processes that are running require a lot of CPU resources, which can slow your computer. If the percentage appears frozen at or near 100%, then a program might not be responding.

Refer to the article for more information:

The article is for Windows 7 but the information applies to Windows 10 also.

CPU won't go above 23% utilization

I have a custom built PC. specs are below. After some recent problems and a full windows reinstall it seems that my CPU won't go above 23% utilization. I have set the power plan to high performance and am using Prime95 to attempt to stress the CPU. When
I look in the BIOS everything looks correct. The CPU temp is reasonable, it detects the CPU as 3.4ghz. Windows also detects that the model of the CPU is correct and lists it as 3.4ghz in system properties. When viewing the CPU on the performance tab of
task manager is lists the speed as 0.78 GHz and that number never changes. It's like it's stuck on that number. Any help on how to troubleshoot this problem would be appreciated!
