It is a hardware problem (either power supply or the card itself or motherboard as mentioned above), and not a driver problem.

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...
I've checked to make sure the card is definitely secure to the board, and that the cable has been screwed in where it needs to be. I'm not sure if my graphics card being a PCI-E 2.0 has anything to do with the problem.

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

Yes, the PSU powerups the motherboard, and then the GPU...

I still think that the GPU is incompatible with the motherbard... That was my situaton...

My friend, who gave me both the mobo and the card, used them together before he gave them to me. According to him, they functioned just fine and he didn't have the same problems with the card that I am experiencing. I'm assuming that the mobo is detecting the card because as long as I have the card in, the onboard graphics disable themselves (or at least that is what I believe to be occurring). And the fan also spins on the card when the computer gets turned on. So I don't believe incompatibility to be an issue here.

hmmmm...

when you say that leaves only the psu to be the problem... What psu did he use (what wattage and how many Amps did it have on the 12V rail?- you can ask him that, im sure that he can answer you.)
Open up your pc, look on the power supply sticker and see the table with the voltage, wattage and amperage. post here the +12V AMPERAGE

Correct. The card doesn't need an external power connection to the power supply, and gets its power from the PCI-E slot; up to 75 W max.

Quote:

Also correct. That card draws around 60 W at load (why it doesn't require the extra power connection), which is also what it draws when you first power on the computer. So is everything else in the computer (CPU, hard drive(s), any optical drives, etc). It then drops down to low power mode (likely around 15-20 W).

I'll get back to you on his power supply, he can't look right now, but he says it's a Corsair and it's either 600 or 800 watts. I'll be sure to get the exacts here soon, he's almost done with his game, lol.

Now for mine, I can just provide an image of the table. See the attachments.

Remove the power cable from all drives and try again. This might seem pointless, but what this does is reduce the power demand on the PSU, particularly on the +12V line (because of the drive motors), and this might just be enough to enable the card to function.

One of my friends recommended that I try removing the power cable from both the CD and hard drive earlier. No change, sadly.

I think that 18 A is little for this card....before buying a new psu, wait for some more answers, maybe we have been wrong, so i don't want you to waste mony for nothing...
If your frend has a 600-800 w psu, and the mobo+gpu worked, then its clear that your psu is not up to the job.

Having seen the image you posted of the label on your PSU, I'd have to agree with the consensus that your PSU isn't up to par for your system. It has multiple +12V rails that are only capable of providing 18A and 16A, meaning that after the graphics card has drawn its power from that rail (I'm assuming the maximum permissible through the PCI-e slot here, i.e. 75W), only 11.75A or 9.75A (141W or 117W) is available to power the rest of the motherboard. A typical motherboard pulls ~30W, and each RAM module ~5W. So that leaves just 101W or 77W for your CPU, which is probably insufficient. (I've used 2 sets of figures here, the first being for the 18A rail and the second for the 16A one. I've also assumed 2 RAM modules.)

I recommend a quality PSU of 650W, with a single +12V rail.
