7800gt DOA or Bad PCIE Slot

[acsguitar]

Just got a new 7800gt which doesn't work

Basically it gives the post beeps that no video card is detected.

AMD 3500+
1 Gig Ram
ASROCK DUAL sata MOBO (PCIE and AGP SLOT)
550w PS

I set the bios to look for the PCIE first then the AGP. However, it never detects the PCIE at all.

The card is an XFX 7800gt.

I've tried to get computer shops to let me throw it in their mobos to see if its my mobo however, no one has a PCIE slot and best buy wants $60 to do it.

Any ideas. I think I'm gonna buy a new mobo and Ebay it if that turns out not to be the problem.

Any chance also that it is the powersupply? I have a new 550w. I'm using two different rails although each rail has a harddrive, or a cd rom on them as well.

The fan spins fine.

Anyways any help would be greatly appreciated as buying a 325$ card only to have it not work kinda ruins your day.

Thanks!

Did you plug in the extra power (6-pin)?

lol ya, did you plug that in also, you should have a warranty on your motherboard, check your warranty and see if you can get the motherboard replaced.
