As soon as I plugged the computer the CPU started to turn on and off around 5 times, after that it stayed on, thru the windows installation I just got to enter the language, then turned off and after that I got a message that says "YOUR PC NEEDS TO BE REPAIRED, KERNEL IS MISSING OR CONTAINS ERROR"... I'm so pissed off, I waited the shipping for over a week (even that I'm prime) and couldn't use the pc not even once!!! CRAP. It has to be a defective power box I think because every time I try to turn it one it turns on and off 5 times until finally starts.
