Windows 7: defective GPU?

defective GPU?

Recently, I bought a new XFX Radeon 6870 and haven't had any luck getting it to display anything in the monitor. I first tried sticking it in the same PCI-E slot of my old gpu and got nothing. I tried sticking it in a different PCI-E slot and still got nothing. Next I used my old GPU to check the device manager and couldn't find the new GPU. I'm pretty sure it's not a power issue since I'm using a 600W Ultra X-Finity PSU. So... does anyone know what I'm doing wrong =\? Thanks in advance.

What's your old gpu?

I hate to be the bearer of bad news, but Ultra PSU's have historically been bottom of the barrel psus... some of them so bad they could do damage to the machine and are to be avoided at all costs.

The Ultra X-Finity is a really old series (surprised they're still selling them) that's, at best, a Tier 4 psu from several years back. You'd be well advised to swap if for a decent one... take care of your hardware.

I still remember at DFI Street the name Ultra just brought shudders every time we heard someone paid for one...

I'm sure you've tried this, but have you doubled checked the power cable(s) to the GPU.
Also the card requires a 500 watt power supply or greater.
Your 600 watt PSU doesn't give you much headroom.

You did register your card within 30 days of purchase for the double lifetime warranty...(didn't you).....just in case its a bum card...but its more likely a bum PSU.....
