After I put everything together when I received it earlier. I connected everything I could. When I turn on the computer everything comes on, the lights and fan, but the screen wont load up. I took out the ram sticks out and cleaned them and back in still nothing. I took all the connecting cables off and on, still nothing. I ran turned on my computer without my ram sticks, everything turns on but I also don't get any error noise or anything just blah, the processor fan runs on and so does my video card. If anyone knows my problem please help me.
