i thing find the problem mr Aleksey-v

, The problem with me at least*, is ACPI meaning Advanced Configuration and Power Interface , if you disable local acpi ,I think your problem will be solved, too, but I do not know how safe they are for the stability of the system ,I mean the stability of the system without that,in the course of time

otherwise you just restart the pc , if this work and after close

The final word is for the people who can fix it

ΥΓ * no local acpi from me not sow all cores from cpu but only one !!!
