I have a Samsung X15 and suddenly here is that the startup screen goes blank. After 5 minutes still nothing. I'm thinking that maybe it's just the screen and behind it launches windows ms my router does not even detected. Thinking it was the screen, I tried to plug another screen but no reaction. So it may be the video card, but I did not beep (Well I do not know if it should beep). After multiple attempts (boot on battery, mains) when he arrived to start but the screen went black after the windows logo and the little loading bar. Another time he has posted 0 on the entire screen, and finally several times he also displayed vertical lines spaced blue and black behind. (When it displays weird things like that, the output on my other screen on). Here I try to identitfier failure.
