Is my motherboard's sound card dead ??

[malakanthropos]

I have an issue the past days, windows say that there is no audio device connected and i have no sound and microphone doesnt work too. It also says that realtek drivers have a problem, i reinstall them multiple times but still the same thing. When i uninstall them now, its say nvidia virtual audio has a problem. I saw a post and i went to computer's management to check if sound is disabled but it says it is working. When i go to device manager under the sound line everything has an icon of a speaker with a yellow triangle and an exclamation mark.

I had a problem like that a couple of weeks ago (i couldnt listen my my mic input was warking) but only for a day then the next day when i entered windows they imidiately fix it by themselves(there was a loading bar)

Is it windows or as title says did my sound card die

Your motherboard sound card and the NVIDIA viritual audio provides audio to monitor speakers, so you have two different devices with the same problem, this means it's probably not the sound card but drivers.. the yellow exclamation icon in device manager point to the audio drivers... but if everything under the Sound, Video and Game controllers section has the yellow mark, it may be Windows has missing or corrupted System files... try restoring missing system files with SFC /SCANNOW typed on a Command Prompt window run as Administrator...

Close all open programs and files / Click the Start button / Select Accessories / right click on Command Prompt / select run as Administrator / insert the Windows DVD / type: SFC /SCANNOW and press Enter... wait for the program results.

Question... you said you reinstalled them... Did you first UNINSTALL the bad/corrupted drivers then restart... or did you just reinstall over the bad? If it's the latter, then the corruption would just carry over.

The best way to uninstall drivers is through DEVICE MANAGER... go there... right click and UNINSTALL... after you do that... restart your computer and then try to reinstall over.

i uninstall them first then restart and install

I did the scan it fix some of the problems it found but it said not all of them, but still no sound

SFC did not fix all the problems it found?
You should run virus and malware scans... it's possible something is preventing SFC from replacing the remaining corrupted system files... If the scanns find and remove anything, restart and repeat SFC /Scannow. If still the problem persists, a repair installation of Windows may be necessary. If you can do that, follow the instructions for your Windows version installation guide.

i scanned the whole computer, avg found nothing, i tried to repair windows and it says that files are missing and asks for the windows installation drive so i inserted the dvd and again the same. So................should i think about reinstalling the windows?Is there a possibility what causing this might be that i am using a windows 8 disk and not a 8.1??? I have the OS before 8.1

Right! you need a Windows 8.1 DVD... but you can Update to Windows 8.1 from Windows 8 for free, but I'm not sure if you can download 8.1 from 8.1 so try and if you can't, the solution should be to install a copy of 8 from the DVD on a new disk partition, and logged on to it, the 8.1 download should proceede.
