Hello, i do not know for sure what is going on but i think it is my mother board. when i turn my computer on all i get it a black screen. i hear all the thing working like the fans and other stuff being on. but all i get is a black screen i think it is the mother board because i plug my keyboard and mouse in but they dont work nor turn on. this is my first computer i built on my own so i could use a little help. Plus i am new at this kind of things.
