I've returned the card to the shop in promise of a new one. I hope it was a hardware error causing the problems.
Tried on XP with the recommended drivers, it was a no go. So I hope it's the hardware.
Windows 7 Professional Won't Detect My Radeon HD 4670

Hello, back again.
I've tried both Xp and Windows 7, neither works.
I got a new graphics card, an XFX Radeon HD 4670, downloaded drivers for Windows 7 64 bit for my motherboard and my graphics card from the respective manufacturers websites. And it won't work. I'm at a loss here. I got a new graphics card and it still won't work. The computer runs fine otherwise, it always has, but it won't detect the external graphics card, regardless of OS/drivers/card it seems.
Any ideas?

you need a better power supply it's not just watts to be concerned about you need enough amps on the +12 volt rail you have a generic power supply that is rated at 400 watts and that's I'm sure max watts not constant and if the power supply is a typical unefficient generic it wastes more power than it produces you will learn that a good power supply is key to a computers stability get something from a brand like Seasonic or Corsair and PC Power & Cooling get plenty of watts and amps the power supply you have is just not enough

your power supply has only 18 amp +12 volts it apparently has PFC but I can't find any efficiency rating for it

lol disregard what he said 18amps is more then enough, just to prove a point ran a 2600pro, amd 5000+ x2 black edtion, 2gigs of adata memory, 2 dvd-roms, 2 hard drives 6 case fans with a cheapy 460watt safe power with only 16 amps to one 12 rail enough said

The 2600 Pro does not draw nearly as much power I know I own one and they put power supply requirements on these cards for a reason you may be running your system with that power supply but 16 amps is not enough to run something like a HD 4670 and 4 gigs of ram plus dual core CPU hard drive optical drives power USB buss devices I mean obviously he can't run either card he has tried this is a power issue plain and simple

The HD 4670 can draw as much as 207 watts compared to about 30 to 45 watts of the HD 2600 Pro also a 4670 requires a minimum of 26 amps

It might be the motherboard - can you go through the points in the troubleshooting 7 tutorial in my sig?

EDIT:
Problem: Windows won't detect my graphics card, it only detects the onboard graphics card (which is a Nvidia GeForce 6150se). The Sapphire Radeon HD 4670 won't even show up in Device Manager, nor is it listed in any hardware-detect programs. When plugging the monitor into the VGA port of the Sapphire Radeon HD 4670, it remains black (no signal). The situation is the same with my XFX Radeon HD 4670.
I will. I checked though all the steps, posting those that seemed relevant for my problem.
Ensure your PSU is up to scratch. Ideally you want an 80+ certified PC that has had favourable reviews and enough wattage on the 12V rail(s) to support your system if you have a GPU installed. There should also be minimal spikes in voltage, as determined by ATX specifications and power should be distributed evenly.
Reply: I have no idea if it's enough, as I mentioned above, I bought the computer-package from a well known swedish site selling packages of components put together by them, garaunteed to work together.
Ensure the IRQ's are not conflicting and that the device may be conflicting with another on the same IRQ. Type msinfo32.exe into the start menu, run dialog box and inspect hardware/conflicts and IRQ's.
Reply: There were no IRQ conflicts.
Try Safe mode to see if the problem is replicated. If not, it's not 7.
Reply: Same problem in safe mode.
Ensure that any hardware and software has Windows 7 compatible drivers and is Windows 7 compatible
Reply: I've checked this thoroughly, downloading the recommended drivers for Windows 7 64-bit from the respective manufacturers websites, both for my motherboard and my graphics card(s).
Overall, I've tried the following:
1. Uninstalling all onboard nvidia drivers / the graphic card drivers, then starting the computer with the monitor plugged into the Sapphire Radeon HD 4670 VGA port / XFX Radeon HD 4670 port.
2. Setting the BIOS prio boot the PCI-E (insteda of onboard).
3. Installing the latest drivers and bios for Windows 7 64-bit.
4. Tried 2 different brand new cards (note that all components in the computer we're sold brand new)
5. Hardware installation went smoothly. Triple-checked it to make sure all cables were connected properly, the fan spins normally, and the card seems active.
6. I've tried both Windows XP Professional and Windows 7 Professional 64-bit. Neither detected the Sapphire Radeon HD 4670, I have so far only tried W7 for my XFX card.
7. Disconnecting the Hard-drive and 1 memory stick to see if it's a power-issue. Didn't work.
