installed new graphic card and now no sound?

February 13, 2011 at 07:36:11
Specs: Windows Vista 32 but, 1 gb
I have just installed my new graphics, the EVGA GeForce GT 240, and now I don't have sound. When I looked at my specs, I saw that I had a video card (Intel GMA 950) and sound card that were integrated to the mobo. So, what I'm thinking, is maybe the sound card and video card worked together, and once I put in a different graphics card, it made it not work. Also, please know that down in the botom right of the screen, near the clock, it says the sound is working, but it really isn't, because I've done numerous tests to see if the sound works and there is still no sound.
Please help.
Thanks

Installing a video card in a mboard slot should have no effect on your onboard sound.

Make sure the speakers are plugged into the right ports.The speakers must be powered on.

See Response 6 in this
http://www.computing.net/answers/ha...

starting at

" Make sure you don't have volumes set too low or muted, for things you want to hear or use.... "

Note that the sound is Muted if the blue speaker icon below the volume slider has a red circle icon with a diagonal bar

Also see Response 5 starting at....

"A frequent answer of mine regarding sound software problems ....."

"When I looked at my specs, I saw that I had a video card (Intel GMA 950) and sound card that were integrated to the mobo. "

Intel GMA 950 is the onboard video - when a video adapter is built into the mboard IT'S NOT A CARD !
If the video CARD was installed in a PCI-E x16 slot, the bios automatically disables the onboard video adapter.
The onboard sound chip is built into the mboard - it is a separate chip from the probably two main chipset chips, one of which has the onboard video built into it. It may use the same IRQ as the onboard video, but that does not cause a problem. Any onboard devices that were designed to use the same IRQ does not cause a problem.

Oh, I forgot to mention that all the jacks for my speakers are plugged in and everything. Also, my new graphics card is in PCI slot, so what do you you think the problem is with the sound?

Any errors showing in Device Manager?

I was advised by someone to go to the bios and check the default settings, onboard audio. I found my onboard audio was disabled as a result of the new installation. I enabled it and voila sound was restored. If you need more specific directions let me know.

"Also, my new graphics card is in PCI slot, so what do you you think the problem is with the sound?"

It certainly can be.

The last PCI slot closest to the center of the mboard often shares it's IRQ with the onboard video or with the video card in the PCI-E X16 slot. In that case, PCI cards other than PCI video cards will often have problems when they're installed in that slot. If there are other free PCI slots, you try the card in another slot one if it's not a video card.

Installing a PCI video card usually DOES NOT auto disable the onboard video if the mboard has onboard video, and usually in that case the onboard video cannot be disabled by using any settting in the bios either. If you don't want to use the onboard video in that case, the only things you can do is reduce the amount of ram installed in the mboard that is shared with the onboard video in the bios,and disable the onboard video adapter in Device Manager (Un-installing won't work).

"I was advised by someone to go to the bios and check the default settings, onboard audio. I found my onboard audio was disabled as a result of the new installation."

The onboard video is NOT disabled when you install a video card. It's always enabled by default. YOU (or someone else who has access to the computer) must have disabled the onboard sound deliberately.

You will have to restart computer. The first screen usually the manufacturer's info shows on the bottom which function key to use for "setup". In my case it is f10, you may have something different.

Make sure you examine and read carefully before you make choices in this area. It is not rocket science but you don't want to accidentally change something because it will affect the operation of your computer.


1. When you get to setup screen you will need to scroll along the top bar. All operations use the arrow keys to navigate. The first category on the left is probably highlighted.

2. Scroll to advanced and hit enter.

3. Should be a drop down menu with a choice for onboard devices.

4. Use arrow keys to get to onboard devices and hit enter.

5. You will see a listing of onboard devices. One should be audio. On the right it will show if it is enabled or disabled. If disabled, enable it by clicking on the right arrow. You will see it change to enable.

6. Click on f10 to save changes and then enter to leave bios. The machine should continue to reboot.

The instructions are giving you information based on my manufacturer's set up. Read when you get to the first screen and you should be able to intuitively find what you need to make the change.

pw ? password ?

Is this your computer or someone else's ?

If it's your computer why don't you know the password ?

The onboard video is NOT disabled when you install a video card. It's always enabled by default. It is unlikely that your onboard sound is disabled in the bios unless YOU or someone else who uses the computer disabled it !

Not true about the audio. I had his same problem. I had sound before installing the graphics card and couldn't for the life of me figure why I didn't have it after I installed the card. I read some responses in forums and was led to check the bios. I discovered the onboard sound was disabled. I enabled it and all is well now.
