So I just got my new ASUS computer shipped to me today and after hooking everything up and going to turn on the monitor, the monitor just said "no signal" and went into sleep mode. I tried two monitors with two different cords(VGA) and both did not work. After talking with three different live chat people, the last one finally said that there is a problem with the VGA port or something got knocked loose in shipping. Just wanted to get some other opinions on this before I go shipping this thing back out. The computer has a 1 year warranty and I don't want to have to go opening it up.

Does it have a discrete video card or are you hooking the monitor to the VGA port on the motherboard?

I'm just plugging it into a port about midway up the computer tower labled "VGA", but I'd guess a motherboard.

I think this is probably it. If your computer has a graphics card you may be plugging your monitor into the wrong port. Do you have a DVI port on your computer? If so, it's likely you need to plug your monitor there. Check to see if you have a DVI/VGA adapter to hook up the monitor.

There is a DVI port right next to the VGA port, but it is too big for my monitor plug(which only fits the VGA port).

Check to see if an adapter came with the computer. If it didn't, I'd encourage you to buy one and try.

I don't believe it came with one, there was only one wire that came with it that we didn't know what it was for(it had clear ports and red wires I think). I'll probably do out and look for one if you think it will help. So what is the difference between the VGA and DVI ports?

Besides the shape, you mean?

Here's a simple article I found:

By the way, the adapter should look like this:

OK, so if they include more than one knid of port on a PC for your preference, why would one work over the other(ie. in my case, why would the DVI work but not the VGA)?

Now we're getting a bit technical and I'm not that savvy on the matter, but it's possible the mother cut off the onboard graphics once it detected a video card had been inserted into the PCI slot. That would explain why you can't get any signal from the VGA port. Again, take this explanation with a grain of salt since I may very well be wrong.

Also, make sure your monitor is set to VGA/Analog mode.

Yup, my neighbor who works on computers(and suggested this one to me) said that it just needs a DVI cable, so he's gonna look around his house to see if he has one I can have. If not, I'll just pick one up for ten bucks. He also suggested getting a UPS, since my pc is just plugged into my wall(ironically enough, getting hit by a storm is how my last PC died)
