I've attached some images to help me explain. I'm not using any sort of adapter, just the VGA cable that came with the monitor (in fact it was the only cable to come with the monitor). The graphics card itself does have a VGA port, which I have been connecting the cable into.

First attachment is the back of the monitor where I plug in the VGA into. Second is the available ports on the graphics card. If you guys need any more images, let me know.

(Sorry if the pictures are upside down or sideways; I took them on my phone)

To make the difference, for you, between DVI and VGA that we are talking about here are the 2 pictures: left is VGA, right DVI. VGA use old monitors (CRT), DVI is often used on the newer monitors (TFT).

Thanks. My monitor is a TFT, but no DVI cable came with it (at least as far as my memory goes)
Westinghouse L1920NW Specs (LCD monitor - 18.5") - LCD Monitors - CNET Reviews also says it came with just one VGA cable, yet says it has a DVI-D interface under "Connectivity". I'm not sure if it even has a DVI, because in that attachment of the back of the monitor, there isn't really anything there for plug-in where the monitor says DVI.

I have little to no confidence in my computer knowledge (this is the first computer that I have built) and I may not immediately get something that might be obvious to you guys, so once again, pardon my un-intelligence in this regard.

That rules out the DVI-VGA adapter. The pictures help as the one you linked too has 2 DVI ports, and not one of each.

Now with that said it is entirely possible that the power supply isn't up to running the card, and the reason why you get no signal when using it. Can't find any reviews on the one you have but found this on the next step up, the V-500,

Coolmax V-500 Power Supply Review | Hardware Secrets

with the conclusion saying it all,

Quote:
The Coolmax V-500 is a textbook example of why you should not buy a USD 20 power supply. Its inability of delivering its labeled wattage is not its worst problem. It presents lousy efficiency between 66.8% and 77.1%, its voltages are out of range, and noise and ripple levels are above the maximum allowed. A perfect weapon of mass destruction. Stay away.
If that is what it is then you need to look at replacing that power supply with a decent quality one. Something like this while still a 400 W power supply,

Newegg.com - Antec NEO ECO 400C 400W Continuous Power ATX12V 2.3 / EPS12V 80 PLUS Certified Active PFC Power Supply

is far superior to what you have now.

It could also possibly be a bad card, but you would have to try it in another computer (with sufficient power supply) to test it without returning it.

I had the same problem when i was instaling my HD5450 in my old pc.
Same simptoms like you have! In the end, i figured out that the problem was the motherboard (it didn't support the 1 GB GPU).
First, i had a 310w psu and i thought that was the problem. After replacing it with a 480w one, same situation! Then i replaced the motherboard and the problem was gone.
Now im on my mobile phone, so maybe i made a mistake, forgive me :O

I think the card isn't seated correctly when put on the MB. Even without drivers windows should run it.

Your spot right on that! Newegg says that the 4670 needs a minimum of 400W PSU (quality one, not some shen-siya-cha mark)

It isn't a Windows problem if you don't get a signal as soon as you turn on the computer as Windows hasn't even started to load at that time. The computer has to load the bios and detect all hardware first before Windows begins to load. It is a hardware problem (either power supply or the card itself or motherboard as mentioned above), and not a driver problem.

I had a suspicion about the power supply, but a lot of my more tech-savvy friends have told me that they are sure it's not the problem. I thought it would be the PSU as the power button will turn the computer on (when the graphics card is secured in the motherboard) but it will not turn the computer back off. I haven't heard any beeping noises, and I obtained the graphics card and my motherboard from my friend who assured me that they both worked without a problem before they were given to me.

If the general consensus is that I need a better PSU, then I'll be looking to purchase that one you linked me to.

Edit: They keep telling me that it's not that the PSU isn't supplying enough power since the graphics card is one that just has to be seated in the MB and not connected directly to the PSU, and therefore it's the motherboard powering the PSU. Yet if I'm right the power supply powers the motherboard, so it just indirectly powers the card. I don't know, you can take this with a grain of sand if you wish, I think you guys know your stuff better than a few of my friends, lol

Softwear aint the problem. Maybe that you didn't place the card in the slot, the mobo doesnt support the card... Did you screw in the 2 litle screws that hold the cable in the GPU??? Maybe the contact isn't good...
