Audio Not Working, Please Help :(

Hey,
im having trouble getting my computer to pick up my speakers or headphones. I will give some history into my computer and what not, to see if it helps.

Purchased in 2009, Specs are
MB Name: Gigabyte Technology Co., Ltd.EG31M-S2
BIOS version: EG31M-S2 FB
CPU Name: Intel(R) Core(TM)2 Quad CPU Q8200 @ 2.33GHz
Memory information: 2,097,151 KB RAM
GPU: 9800 Geforce

my hardrive crashed the other day, so i had to get a new one. So i did that, then i ran into another problem, of my computer turning off after 10-15sec, i took it into a shop, and they said that the mobo fan broke for some reason and was resting on my cpu, causing it to turn off.

Anyways, so i re installed windows and all the drivers, installed wow and noticed that the sound was not working. So i played a mp3 audio file to see if it was just wow. It didn't work, so i went to my audio manager and its telling me i have no audio device connected.
I thought maybe my driver did not work, so i re-installed it, still nothing. (Realtec High Definition audio Driver).
I went to device manager, and next to my PCI device is a yellow question mark, and i remember reading somewhere that thats your mobo sound card thing. so im guessing that could be the issue? i went to update it, it asked for a cd, i out my mobo cd in, and nothing happened.

Im not even sure if im on the right track. Please help

 

Maybe your Motherboard on-board Audio Drive / Device is spoiled/broken. You might want to research more about it and maybe invest some into a external sound card.

 

Yellow question mark = No good driver installed for it.

Teamviewer me and I'll fix it for ya.

 

You need to install motherboard chipset drivers, so it can find out your audio device. Then you install audio drivers, not the other way.
