Acer Aspire E1-531 screen gets totally black

Hello,


I have an Acer Aspire E1-531 with Windows 8.

Yesterday it becomes slow, so I decided to turn it off, and then turn it on again. The problem is that the laptop turns on, it appears the Acer logo, but after that the screen gets totally black, appearing only the mouse pointer.

I've already tried to turn it off and on many times, and nothing works.

Anyone what's can be causing this problem?

Thanks.
