PC won't boot after installing Sound Card

Hey Logan, Wendell and everyone else on the forum,

Today I got myself an ASUS Xonar DGX sound card,But after I plugged it in on my Gigabyte Z77X-D3H motherboard my PC wouldn't boot anymore.I can't even go to the BIOS.. (no post-beep at all)

I've tried this several times, but I keep getting the same results..

(I have noticed that the capacitors on the sound card are slightly bent. All of them. Not sure if that's bad or not)

Any troubleshooting tips?

Thanks!

Can you post pictures of the sound card? And also try taking it out and see if it boots. First thing I would do.

I honestly have nothing to take pictures with. But the capacitors have slightly less of an angle as this: /.
(the forward slash)

When I take the sound card out, my PC works as before.. I have no clue what it could be. 

I'm afraid I cannot. This is the PC I built a couple of months ago. My old PC doesn't even have a PCI-e slot. The rest of my family is using laptops.. so yeah..

As I have had PCI-e slots at my disposal only for a couple of months, this is the only expansion card I've got.

Did you disable onboard audio?

Try tilting the card up or down.

Try tilting the card to the right so it's not hard up against the rear of the case.  Sometimes cases are a little out of spec but just within tolerance.  And end up pulling the card out of the slot.

Also does it sit on the piss? or parallel with the pcie slot?  Sometimes the bracket needs to be removed and the tabs bent to 90 degrees so it sits straight.

Also check your motherboard manual for the slot assignments.  Usually there's 1 pcie 1x slot disabled to optimize bandwidth for 3rd party sata controller.

Go into the BIOS options and disable the realtek onboard audio chip, save and reboot.

I'll try all of them, thanks so much! 

I will, thanks!

Cool.  You also have 4 slots to try.  I would be opting to have it in the top Pcie x1 slot or the bottom Pcie x16 slot which runs in x4 mode, but by running in that slot all 3 Pcie x1 slots will be disabled.

Pcie x1_2 is most likely disabled by default for the marvell controller.  Pcie x1_3 I'm not sure of however and the user manual dosen't seem to have a shared resource map unless I missed it.

As for the capacitors being bent that shouldn't pose an issue unless they are actually broken at the pins.

You may also need to update your Motherboard bios.  That could be worth a try aswell.

Yeah, I originally had it in the top PCI-e 1x slot. This way it doesn't block the airflow to my 7970.

I've tried the other PCI-e slots. Here's what I've got:

The top one doesn't work, but we knew that already.
The second one isn't available, because my GPU is in it.
I don't want to use the third one, as it'll block too much airflow to my GPU.
The very bottom PCI-e 16x (4x) slot doesn't work either,

But the fourth slot (PCI-e 16x (8x)) does work. My PC boots with the soundcard in place.

The only thing is: It blocks quite a bit of airflow to my GPU, which is already running hot.
And this also means I can't go SLI/Crossfire anymore.. 

When I tried to install the driver (of course from the ASUS website, not from the CD), it takes a loooong time, and then at the and, it says something like: "Attach the DGX sound device". As if I suddenly detached it..

What do I do?!

Did you ever disable the onboard audio?

That means you need to go into BIOS, disable the onboard sound chip, and tell the motherboard to route sound through the sound card. Instructions will be in the manual.

Well, here is my suggestion for you.

#1 to resolve the GPU overheating issue.  Download your manufactures software for manipulating the GPU.  I have a HIS video card, so I downloaded: http://www.hisdigital.com/us/news_show-237.shtml  And it has a option to chage the curve of the GPU fan, which I just raised 5% overall, and my card stays about 10c cooler.  (this software from HIS SHOULD be compatiable with other vendors, but its not guarenteed)

 

#2 I am willing to bet, more than anything your PSU or Motherboard doesnt have the power to drive the extra PCI card.  The last slot you tried (the one where it worked) I assume was a full sized slot, thus its able to squeeze out the last bit of electricty.  What kind of PSU do you have?

re: #2: It's definitely not that :). I have a Gigabyte Z77X-D3H motherboard, which, as the name suggests, has the Z77 chipset, which is the best of the Ivy-Bridge. (except for the new X79). And my motherboard is capable of overclocking, it says this right on the box. It should be able so power a €30,- sound card.

I'm also quite sure it's not my powersupply, as I have only one GPU and it's 750W.

I've finally been able to install the driver for my sound card! =D

In the end, it was probably just necessary to reboot my system.
(not sure about this, because is did a fair number of things before trying again.) 

Thanks for all the help you guys! It's much appreciated!

If you have any tips on good ways to test my sound card and get the most out of it now that it's new,
let me know! 

Awesome stuff.  I suspect you may have a dud Motherboard.  The card should work in the first and third slot.

Also do you know what bios version you are running?
