Gfx card not being detected.

Specs: Windows 7
Hi all, I recently bought a brand new computer from scan, and an ATI Radeon 6870, from Aria.

I build the computer, put in the graphics card, and when I turned it on, nothing. I switch over to the integrated gfx card, it comes on perfect. I then install my drivers, windows etc, all seems good. I install two games, run them on my integrated card, and they work fine. Next day, I start the games, they flash in and out of the game, going from the game to a black screen, then when i try to change any settings, my computer full on crashes.

Main problem is that it doesn't detect my 6870 though, and now my intergrated can't even play games on that without my computer flashing in and out of the game, then crashing when clicking something.

I run:
Windows 7 Ultimate
Asus P8Z68-V Pro (Motherboard)
Ati Radeon 6870 Graphics card (Not detected)

Any help would be much appreciated, Cheers, Millzee.

We need the complete specs in detail - CPU, RAM & especially the power supply.

You need to install the card & make sure it's fully seated in it's slot, connect the TWO required 6-pin PCIe plugs, & connect the monitor cable to card.

I thought I put the CPU, Sorry. I'm running an Intel I7 Sandybridge 2600k Unlocked, 4gig of ram, And it's a Corsair CX600 Power supply.

I installed the CD drivers, tried installing the ATI Catalyst centre, to no success. It's seated properly, I tried the other seat on the motherboard too, It's getting power as the fan's running on the 6870, but when I plug the monitor into it, the screens black because it isn't detected.

Dirvers are supposed to be installed AFTER the card is recognized by the OS, not before. And you didn't say whether or not you connected the two 6-pin PCIe plugs. You also need to go into the BIOS, disable the onboard, return the shared memory to the system, & make the PCIe slot the primary display adapter.

Yeah, I did connect the two 6 pins so the card's getting power, Fan is spinning but not being detected at all, since I first started the computer.
