Hi

I just reinstalled windows, till format it works totally fine.

Now when i plug in an external display via HDMI Process process name: "System" starts to use CPU pretty a lot 20-40%. In detials its: "ntoskrnl".

While using display it can lag on some actions like: notification bar: lags, i can wait TOO LONG to unfreeze or just unplug hdmi and it starts to work fine.


Just in case: i installed/reinstall all drivers according to Intel/Nvidia graphick.


My last BSOD was:
