That’s crash after boot. Is there an OC?  Most common (but not the only) reasons for crash after boot with no OC are ram problems or PSU problems.  It seems to be very occasional

Nope  there's no overlooking

I just turn on the xmp profile and also I change the psu by new one evga 750bq. 

Like u say maybe it's the ram I will buy a new one to make sure of that

XMP profile is memory overclocking.
