Hi all, I just finished building the following PC:

CPU: Core 2 duo E7400 (2.8Ghz)
MoBo: Biostar TP45 HP
RAM: Corsair PC2-6400 2x1GB
PSU:Coolermaster iGreen 600W
Graphics card: Nvidia Geforce 9800 GT

When I turned it on everything worked (all fans spinning, lights working, hard drive spinning) except the 2 LED's on the motherboard indicate that there is a VGA error. So I removed the gfx card and reseated it, same problem.

At first the gfx card was powered by the molex to 6-pin PCI-e adaptor that came with the card. When I removed it and powered it directly from the PSU both LED's came on (alls well) but still no image reaching the screen. I checked the cables and restarted the PC and the mobo LED's were back to VGA error.

Each time there has been an error the POST BIOS beeps have indicated a VGA error.

Im not sure whether its a faulty card, incompatibility or a power issue. Any help will be appreciated.

It's a difficult one to troubleshoot without trying the card in another computer. It could be a Power issue, it could be a faulty card, or even a faulty motherboard.

You have a pretty hefty PSU, so I don't think that should be an issue. I would suspect a fault card, but it is best to try in another computer to see if it works there.

I've set it up out of the case on cardboard, with just CPU, RAM and graphics card, but received the same problem.
I also tried clearing the CMOS, that didn't help either.
I tried running it with 1 stick of RAM and then the other, but still got the same beeps.
I'm trying to hunt down someone with a gfx card that i could use, or a PC with PCI-e x16 2.0 slot, but I'm having trouble with that unfortunately.
