Why does my HP 15-f009wm laptop have a solid black screen upon startup

My HP Model 15-f009wm Windows 8 laptop has a solid black screen upon startup. I'm honestly unsure as to exactly why, or if it can be fixed or not, but my HP Pavilion laptop was doing the same exact thing 2 weeks ago and I was able to fix it by taking the bottom off of it and that's where I seen that the ram stick had jarred itself loose somehow. I securely snapped it back into place and then it worked, but honestly I don't think that I have that option with my 15-f009wm. Someone please help me out.
