Black screen on Windows 8 lock screen

Question

Windows

Recently there was such a problem. It seems to have been decided. And now - a new miscarriage of the system. I left the lockscreen on - I come - a black screen and nothing can help get out of it. Only off with a button. What was it?

Answer 1

For me, here is my working Asus laptop (or rather, the Asus utility) constantly displays messages something like: "man, I may not turn on after a long idle time in standby mode" And it happens that it does not turn on, you bastard. So it's a laptop problem. Home laptop, during the 2-year run on Windows 8 works like clockwork.

Answer 2

It was the same, pulling out and reinserting the video card helped (maybe there was a backlash).
