Is this a broken graphics card or insufficient power?

Hi there,

Just bought a new GFX card - Gigabyte factory overclocked GTX 570 - and it seems to be having some issues.

On startup, there are really bad artifacts + image ghosting which gets progressively worse until it seems to "reset" and go away and the problem starts again. I've put the old card back in and its working perferctly so think motherboard is OK.

Here's some pix of the images getting worse and one of my PSU.

I'm presuming its either a bad card or the PSU isn't powerful enough. Can anyone offer me any clarity before I get in touch with the supplier of the card.

Cheers!
Dan

A few questions:

1. What was your old VGA? If you were using an AMD/ATI VGA, you may be having driver conflicts.
2. Are you overclocking CPU/RAM? If yes, try running stock clocks.
3. Have you connected power correctly to VGA? ie both 6 pin and 8 pin.

If problems persist, I would lean towards a bad card. Your PSU looks fine.

It looks like bad RAM in the GPU to me

1. An HD4800 - Did an uninstall via Catalyst Control Panel. Does something like driverclearpro still exist?
2. No, its all running stock.

Uninstalling from CCC can still leave remnants in your registry.

Use driversweeper. Uninstall from control panel, boot in safe mode, run driversweeper and select AMD/ATI and NVIDIA (not chipset) components then reinstall drivers.

Wasn't sure which model you were using. I think some models use 6+8 pin.

Just done this - Same issue.

I'm presuming this means bad RAM then?
