Hello , I have had the problem of black screen the same day I received the PC. I turned on the computer for the first time , started the configuration of windows and crashed. I had to forcibly shut down the pc and then you are no longer on again. Problem: black screen , all the LEDs on except the processor, after 30 seconds the fans run indefinitely . After several attempts , turning on and off , the PC is started , I did the updates of windows update and these days I was not given more problems , I think I've also updated the video card driver . Occasionally, however, the computer takes too much to go off or after I put the windows password is not accessed . I asked for a refund because where I bought it is no longer available and I want to buy it back at another site to 200 € more than what I paid , but I'm afraid I have the same problem . I sent an email to asus in which I explained the problem and they responded with a short sentence : " it is a hardware problem , replace the PC ." I was not given any explanation , bad service . I believe that even they know what the problem is due . Are undecided whether to let me replace because the problem is not me giving more , but I think of the money I spent and the pc has given me from the start. We can have a definite answer on the issue by this company ? I think I 'll buy another laptop of another brand . I used google translate.
