Help, mining gurus

Something strange is going on with my PC or mining software, I'm currently mining on VIABTC Pool with GPUs only and I noticed that my CPU is underload of 74%, why is that when I'm only using GPUs? Core i3, what's up with this?

What coin do you mine, what video card do you have?
What software do you use?
What OS do you have? What's your hash rate?
We cannot guess these parameters.
Describe your computer configuration

This isn't strange to me because I'm 100% sure that your Windows OS is downloading updates and will be installing the updates soon that's why the CPU is on load, you have to stop the windows OsS update, use google to find solution

Two things are involved here, it's either your PC is upgrading in the background without you knowing or your PC is infected with those trojan miners that use people's available resources on computer to mine without the owner knowing

When you open Windows Task Manager, which process is occupying the highest percentage of processing?
It is probably some task of windows ... finding out which one is easier to find the solution.

Task manager will reveal the problem but I used to get cpu on load when Windows10 is updating OS in the background, if you are using WiFi hotspot make sure you set a metered connection in wifi settings this will stop windows 10 from downloading updates

Close all applications and browsers.
With an open browser, the AMD Athlon X2 processor is loaded by 30-70%. If my browser is closed, it turns out 4-20%.
Did you download the miner from the developers github or from a third-party site?
