Story goes like this:

I had registry error bluescreen of death. I couldn't fix it but found that recover computer to the last working setting should work, yeah it's worked but my sound disappeared also my device in the device manager. 

How should I fix it? (Lenovo G580, Windows 7 SP1 x64)

How I can uninstall old ones as I can't find any device in device manager? There is possibility to uninstall it somehow ? 

 

 

The problem with re-installing the drivers is like this that it says that there is no device for those drivers. :(

Hi ReadLiaoFanBook :)

If you go in your Device Manager, and select Show hidden devices in the View many, does your audio device shows up under Audio Controller? If it does, does it have an error message? If yes, what is it?

@Aura

 

Thank you for coming to thread! 

 

Nothing new popped out after selecting this option sadly. I found that there is Nvidia stuff which was not aware off which it could be installed because before I tried to fix it on my own and just installed and updated drivers so probably because of that.

Then it seems that your sound card isn't even detected at all by the system, which means that it might be lose or there's a another physical issue with it. Usually, the NVIDIA Audio Drivers can be installed/updated via the NVIDIA Graphic card drivers installer that you get from the NVIDIA Drivers webpage.

Yes exactly. this Nvidia audio drivers is not really my drivers. I used Conexant audio drivers. So there is nothing that can be done?

If I were you, I would check if physically the sound card is well connected to the motherboard and see if after that it re-appears in the Device Manager. Below is the user manual for your laptop, you can look throught it to find the sound card location in it and then disassemble it to verify the connections.

If it's integrated, then check to see its integrity: no traces of sparks, burn or other physical damage on it.

There's not a lot of ways to reset the password on a BIOS. There's many "methods" going around the web, but none of them really works. The best one is to call your manufacturer with a proof of purchase, so they can give you your BIOS mastercode to unlock it and remove the BIOS password.

Well if there's no sound card, they won't work. You could try using an external USB sound card I guess but you would have to buy one if you don't have it already.
