Graphics card no display

  Alan-Petrie 18:33 13 Mar 2009

Hi I recently bought and installed a new graphics card (HD2900) previously I had a (HD2600) I thought I had fully uninstalled the hd2600 drivers as when I used windows the measure the performence of my computer it told me I had no graphics card driver. I then swapped the graphics card and plugged in both the 6pin adapters for the hd2900, the fan spins and the bios beep is still heard howvever nothing appears on the screen.

sorry I didnt mean to post that message.

I am running windows vista and my power supply is a hiper power rated at 580watts (thats not the peak power) and 30amps on two 12volt lines so that should be fine since the card only reccomends a 500watt power supply.

If there is any more information I am happy to help.

Thanks Alan

I swapped the old card back in and all is fine. So I have I have no idea what could be wrong.

May be a resolution problem. Can you boot into VGA mode and sort out your resolution problem or reinstall drivers. Sorry not a great expert on these matters.

I had a card that would not work I sent it back and it tested ok, I needed a bios update to get it to work.

Hi thanks for your help I tried the bios update but it had no effect.

could it be possible reinstalling vista would help in case there was files left on the hard drive preventing the new graphics card from starting.

turns out the problem was the dvi cable. the card just doesnt seem to work with that particular one. But it works fine when I connect using a hdmi cable. Thanks for the help Alan.
