    CPU Spike after Windows Update


    Hi everyone, I got a Lenovo ideapad Flex 15D. I am currently having a problem so several have surely already encountered. Some of them call it a lagging mouse problem but in fact when i look to the task manager, i see that the processor is having latency problems. Every 2 to 3 seconds, cpu spike. There was a solution i found ( soundcard drivers problem ) so I tried to install new drivers for the sound card, deleted the file fmapp.exe, moreover, fmapp.exe did not appear in the task manager when some says it was . When i format the computer, everything is fine but when comes the time to do updates and installed them, problem comes back. I disabled the sound card, deleted the fmapp files from the computer and even put in the latest drivers from Realtek. I cant find any later bios update. I did look on lenovo diagnostic tool and lenovo support for updates and all was fine.

    Do not know what to do now. I need a miracle haha.

    ( Model 20334, MFG date 2013/11/21, bios version Lenovo 94cn05ww ( 2013-10-14 ) , Version SMBios 2.7 ) Using Windows 10 home.

    I tried Linux mint to see if it wasnt the computer itself, but work well on it. Problem really came with some of the drivers update, but wich one ...

    Thank you !

    Welcome to the Forum

    If you disable the sound card on device manager, does it work good?

    I think you would better state which exact processes caused the spike of CPU usage as well, also disable the auto update feature especially for drivers because win10 has the habit to replace your specific or OEM type drivers with generic versions which in fact caused a lot of driver related issues.
