I had no problem with my Lenovo Z51 laptop before so this is my first time encountering this issue. When I am trying to start up my laptop, the Lenovo logo appears and then leading to the black screen with white dot circle spinning. It has been like that for hours. Must be something wrong with my laptop. Having googled other support forums for some answers in bid to solve this problem myself, I have tried the system restore method, restoring to the recent date but this method has not still solved the problem here. Since I am not quite a computer expert, so I am asking you to help me out with this problem. What should I do next to solve this problem? Please please help me out with this. Many thanks in advance.
Please see below the image, as this is what I get on my laptop - BLACK SCREEN WITH WHITE DOT CIRCLE SPINNING NON-STOP.
