on a blank scene, doing something like creating one object take several seconds even some times minutes
doing something like a basic fire setup (from the shell) is impossible, I was waiting for more than one hour and nothing
I was cheeking on my Task manager and the resource usage is low, like 10%CPU 20%RAM 10%HDD
It was working fine before, but suddenly started to run slow, I tried format the HDD making a fresh reinstall of only the basic, and still doing the same
I don't know what else to do, please some help

Thank you guys!!
My Laptop:
CPU i7 8core 2.5GHZ
