My monitor wont display a signal(and other monitors) I made a previous post about this thinking it was the monitor but I tested different monitors and different sources and plugs. I came to the conclusion that it was the pc ( i built it myself) everything runs though I don't know if the ram is ok is there a way to check this. I don't want to go somewhere to get this fixed I would like to do this myself for now. I also don't have windows installed because I want to see whats happening. Please give me suggestions on what to try. Thank you
