PCI slot not detecting anything with new mobo

Specs: Windows XP SP3, amd a43300
Hi all

So I put together a simple rig last week using a Gigabyte GA-A55M-DS2 motherboard.

Everything seems to be running great, except the PCI slot, which there is only 1 of (that's all I needed)

I've tried 3 different fully working cards (tested in other PCs with same OS) so I know for sure they work.

I'm using XP SP 3. Problem is, windows detects the cards, I install drivers for them & windows says they're working, however they aren't and there seems to be some sort of communication issue, almost like the PCI slot has a firewall.

Of the 3 cards i've tried 2 were sound cards and while windows says they're working, there's no sound to be had regardless of what I connect to the cards and how. I tried an Ethernet card last night and again, same thing. Windows detects the card, says it's working, however it won't connect to the internet and displays a ""network cable is unplugged" error.

BIOS is updated, not sure what else could be wrong.

Any help/suggestions would be appreciated...I'm starting to think the PCI slot is damaged. I also tried 3 different PSUs...same results.

The motherboard has sound & ethernet, so why do you need either of the cards? They're obviously being detected so that means the PCI slot is not at fault. If sound is the one you want, did you enter the BIOS & disable the onboard sound?

"I also tried 3 different PSUs...same results"

Of course, because it's not a PSU issue.

Well I just wanted to use my HD digital sound card which is far better than the onboard. None of my PCI sound cards worked in the pci slot, so I started trying different cards- i.e, ethernet cards. I do use the on-board ethernet. I'm just trying to get the slot working so I can use my Audigy sound card...but no card is fully working in the slot. I have disabled onboard audio & updated BIOS, but nothing. I also just found ANOTHER pci ethernet card and tried it in the slot and received a "this device cannot start" error...so there appears to be something wrong with the PCI slot.

From the manual:

Onboard Audio Function

Enables or disables the onboard audio function. (Default: Enabled)
If you wish to install a 3rd party add-in audio card instead of using the onboard audio, set this item to Disabled.

I assume you installed the motherboard chipset drivers & uninstalled the onboard audio drivers (if they were ever installed)? Also, you MUST have SP3 installed for HD audio to work. It should have been installed before the HD audio drivers.

Hello again thanks for the reply

Yes I installed all chipset drivers after a fresh install of XP SP3.

But this problem is not limited to just HD / sound card issues as NO CARD I put in the PCI slot is working even though Windows detects it and says it is working. I have tried 4-5 cards so far, some sound cards, some ethernet cards, all with similar results...none of them work even though they're showing up in device manager

I can't see what you're doing but it sounds to me like a configuration issue, not a hardware issue.

Just for the heck of it, I formatted my drive and this time installed Vista. Same exact issues. Gonna have to just RMA the board. I also tried the onboard sound and there's nothing but insane amounts of static coming from whatever I plug into the onboard port. The static is such that I can actually hear what's going on inside my PC case through my speakers/headphones...even when I move my mouse it makes a buzzing noise. Ridiculous. I'm sending this board back to Gigabyte asap. I will post an update as to what happens once they receive it and test it, for documentation / anyone else having a similar issue in the future.
