Hi. I have a 3 week old ROG GL502VM and i noticed a problem since last week. Whenever I turn on my laptop, after the ROG logo, the screen flashes BLUE before showing the (username and password option in the screen, idk what it's called). But then, whenever i turn my laptop on, after the ROG logo, it goes BLACK. I had to turn it off then turn it on again so it may work, what could the cause of this be? I remember having this problem as soon as I updated my windows. I only have CAD, Dota, CSGO in my laptop and no viruses so far, could this be a software or hardware problem? does resetting my laptop help?
If it's only 3 weeks old, I would recommend a factory reset. In Settings>Update & Security>Recovery, select the option that erases all files completely and re-installs the OS from scratch. I forget the exact name of this option, but all the other options involving keeping some of your files or going back to a previous version are very unstable in Windows 10.
