So I just spent over $600 to get a decent gaming computer, no monitor included of course because I already have one. It just got here today and I hooked it up and it looks like it's running fine, beeped once on start up and the LED lights lit up and the fan was spinning. However, when I hooked up the monitor it says "No signal" for the DVI and VGA. I've tried two different monitors to see if that was the case but still said "No signal". This is frustrating and since the computer is new and expensive I'm scared to open it up and start messing with things because I have no idea what is what. (I'm only 15 btw, my parents don't know about computers at all so I'm by myself with this) Please help!
