Guild Wars 2

I just got a brand new computer from Cyberpower PC and I’m trying to hook it up to play the game, but the monitor isn’t working. Both cable ends are connected, but when I boot up the computer and monitor it just says “No Signal” then goes into sleep mode. I can’t do anything.
I ordered the computer with no operating system because I already had a Windows 7 disc and wanted to save money. The monitor is a 17" Acer V173 that I got for free, the cable is a VGA.
Can anyone help me out?

Are you plugging in the VGA cable to your discrete graphics card or the port on the back of your motherboard?

I literally have no idea what you’re saying.
I haven’t opened the computer casing yet, it came prebuilt. I just plugged the cable into the back of the tower. So….the port on the back of my motherboard?

OK, so, apparently there’s supposed to be two VGA ports on the back? Mine only has one, the one to motherboard, since it’s above the audio ports.
So now what?

I’ll tell you now what, me!
You go to Radioshack and buy yourself a VGA-DVI adapter from a fat man with a funny name, plug that kitten in, and you’re set!

Thanks, me! I couldn’t have done it without you!

So I’m assuming you fixed your issue or do I need to go into a little more detail?
