Hi, recently I've been having some problems with my computer. The monitor occasionally won't turn on when the PC does and the computer sometimes crashes. I've been hearing that this is mainly an issue with my ram and I took one of the sticks out and it works fine however, I tried to put in two brand new corsair vengeance DDR3 8gb sticks of ram and the monitor also wouldn't turn on. I'm wondering what could be causing this. Is it a problem with the ram?
