I just installed Windows 8.1 x64 on my Laptop and I've encountered the following problem:
When I restart the laptop, the screen turns off after Windows logo shows up. Just before the "signing in…" page.
If I connect an external monitor everything works fine. I tried change back to original monitor but nothing happened. As if there is no original monitor.
The really strange thing is, that when I shut down my laptop, I turn it back on and everything works normally. The problem is only with restart.
Why is that happening and how can I solve it?
Note: My GPU is NVIDIA GEFORCE GT540M. If you need more hardware information please let me know.
Edit 1: Screen is not off. It is just black.
Edit 2: Now I have the same problem with shutdown too…
Edit 3: I installed windows 7…….. I'm afraid I lost this battle….
Edit 4: I found a workaround but I cannot accept it as a solution but maybe it will help us. I noticed that when I restart my pc and get that black screen, if I put the pc on sleep and wake it up 5 seconds later, I get normal log in screen and everything works normal from that point.

There are differences in the way windows shuts down opposed to restarts. This is probably why you are only getting the black screen during restart.
Difference between shutting down and turning on vs. restart in Windows 8?
When you say the screen turns off, is it off or just black?
Are you able to pull up the task manager (ctrl+alt+del)?
