Alpha R1, not showing display after logging in

When i turn my computer on, Sometimes it shows (This computer was not turned off properly) And most of the time it turns on and goes to the screen, When i login I can't See the screen it goes black for like 5 seconds and then It says no inputs on my Monitor. I dont have a factory reset option in my Advanced options. I tried to use cmd prompt in the advanced options but the video i watched didn't work.

I need help so if someone can figure this out then thank you.
