CPU spikes

[Daris17]

Hey,

I have strange problem my laptop experiencing cpu spikes 90-100%.

Laptop model: lenovo legion y520

CPU: Intel core i7-7700HQ

GPU Nvidia GeForce GTX 1050Ti

Intel(R) HD Graphics 630

Motherbord: Lenovo Provence-5R1

RAM: Samsung M471A1K43CB1-CRC DDR4 8GB

1200Mhz

Storage: Samsung MZVLW128HEGR-000L2 128GB

WCD WD10SPCX-24HWST1 

1TB.

So i have this computer already 3 years and about 1 year ago i started notice some cpu spikes when im gaming, i dont use hight graphics so its not this problem because i get these spikes even when someone invites my to their lobby in csgo or starts playing game on steam and i receive notification. So i thought maybe some malware or something so i check for viruses, didnt helped, i did sfc scan, also nothing, performed clean windows reinstallation, also nothing and finally i changed thermal paste, and i was dissapointed because it didnt solve the problem so im asking you guys maybe any of you had simillar problem before and found solution?

screenshot task manager when the issue happens. (both the main tab and the performance tab)

 

is windows up to date?

did you run windows memory diagnostics?

contacted lenovo support?

There you go, im not able to make screenshot at the peak of spike, because cpu usage just goes down very fast. But as you can see in performance tab it goes fully max.
Yes my windows up to date,
I didn't contacted lenovo support yet.

Im not sure how to do win memory diagnostics, but i will check online.

Try updating bios it helped me to kinda reduce CPU usage also add a windows defender exception for all your game folders and steam folders.
