I have a Dell XPS 15 L502X notebook. When I power on the computer doesn't jumped to the Dell startup screen but instead a black screen with the noise of the computer fan running at full power appeared. I have to power the computer on and off for 10 times before the dell start up screen showed and then windows started to show. Worst still, when windows start for a while before the desktop is loaded the screen went black again and I have to power it on and off for a few more times before it showed the windows launch startup repair or start windows normally screen after which I have to choose the start windows normally screen before I can start windows properly. According to Dell diagnostic all my hardware is working fine. I have also updated all my drivers to the latest version. What is happening?
