Sound not working and Laptot slow now.

[HenryOfFinland]

So. It all started yesterday 11.10.2018. I was at school and my sound worked just fine. I wanted to shut my computer down and I saw the option: "Shut down and update". Well I did not want to update so I force shut it down. Then I came home and my sound did not work. I saw the red "X" in the toolbar on the sound icon. Well I thought that it was a small thing. I put my mouse over it and it says: "No audio output device is installed".

So it was a problem now. I watched a video on youtube and it told me to go to device manager and uninstall everything under the "sound,controller and gaming" or something like that and I did uninstall everything there. Then it told me to check for missing things or scan something like that. I did it and nothing happened. So the problem grew.

The I remember that I force shutted my computer rather than update to perhaps updating will save the day. And it did not. I watched more videos and read a lot more things. I tried to download the audio driver from HP homepage and the installation did not work coming up with an error message.

So I tried the last resort. Refreshing my computer completely. I waited for many hours and well. I was certain it would work. As it "should" bring back all the original devices and things right? Well it did not. My sound still did not work. It was getting very problematic. I waited till the night and at school next day I realized that my laptop was now extremely slow. Booting it up took like 10 minutes whilst usually it took only a minute as this is an gaming computer. I have not tried any games yet but my sound doesnt work anyway.

Loading up pages takes forever. I took me atleast 20 min to get here to HP support. 

So please. I ask if anyone can come up with anything. Please.

The sound we do have a fix for but first lets start with your HDD.

Power-on and start tapping the "esc" key.

Run the Hard Drive Diags/Tests.

Post the results.

So I did the "fast test" first. And the results are: Fast test: PASSED. But I think I need to do the extensive test right?

@HenryOfFinland

It will take a little more time but please do run it.

So now I did "component tests" and then Audio test. And there was speaker sound so the speaker is not broke. And I selected end sound and I got: Audio playback test: FAILED.

Thank you!! Its incredible the sound is back!

Only thing now is its kida slow. Could it be because I refreshed the entire computer? Or could there be something else?

[HenryOfFinland]

False alarm! After fixing the soud the computer seems to work absolutely fine.

Thank you so much! You are awesome!

Make sure you do a Disk Clean-up and then a Defrag monthly.
