Windows 10: Weird hardware electric noises + rapidly heated

The computer I use is school provided so I don't know a lot about it. It's just that it makes weird electric noises coming from the left of the keypad. Also the fan function a lot but I think it's normal for the computer to get heated after a long time of use but now I jusste used it for like 10 mins and it's hot underneath. There is no system message telling me it's a problem nor has the computer been experiencing difficulties on anything I use. I also transport it in a bag in a very shaky vehilcul called a school bus everyday.

Weird Noise after Anniversary Update

Hello John,

Let’s check what is causing that weird sound on your laptop.

Based on the link that you had provided, it seems that it’s either your CPU fan or Hard drive which is creating that sound.

If it’s the CPU fan, it might be an issue due to heavy processing, processor heating up or changes made during the update. If it’s your Hard drive, the issue might be with HDD performance. We suggest you to back up all your data to your external drive
to prevent data loss.

Follow these steps to resolve your issue:

Step 1: Check your Task Manager

Close all applications and check in task manager for any high usage of resources by any process.

• Press Ctrl + Shift+ Esc together to open task manager.
• Click on more details and check for any apps that is taking more resources.
• Take note of any Applications that are taking High CPU usages and try to disable it if it’s not that important.

Step 2: Start your computer in Safe Mode

Safe mode will start computer with basic drivers to check what might be causing the issue in normal functioning of computer. Check if the weird sounds are still happening.

Start computer in Safe Mode

Step 3: Run Hardware and Device troubleshooter

• Press Windows + W, and type troubleshooting.
• From the search list, click on troubleshooting.
• On the left pane click on view all to get the list.
• Click on hardware and devices troubleshooter.
• Follow the on screen instructions to complete the troubleshooting.

Hardware and device troubleshooter is an inbuilt troubleshooter that will find the issues with hardware devices and try to fix them automatically.

Let us know what happens.

 

Noise/hiss produced by Windows(?) on the audio output (not a hardware issue)

In case you haven't already, ensure all inputs have been disabled and are not part of the mix you are recording. Just because you are recording what is being sent to the DAC, doesn't mean Windows hasn't already mixed in some electrical noise on an input. In fact, I would disable the input completely and lower the recording volume on the mix to zero.

To determine if the issue is hardware or driver related, I would install a different OS on a temporary drive, or boot from a USB key (https://www.ubuntu.com/download/desktop/create-a-usb-stick-on-windows).

If the problem goes away then it is a driver issue and you may have a chance of fixing it by manually installing an different driver version, or even a generic one if it exists. There is still a small possibility that it's a hardware bug uncovered by a driver-specific feature.

If the problem persists then it's quite likely a hardware bug. I would still check where in the boot process the noise starts (power on, after hardware init and POST, during OS bootup, after the first OS sound plays, after application start). If it's after the OS starts then you may have some luck with drivers. If it's before OS startup, then there is likely not much you can do, save for a firmware update.

Good luck!

Update 1

I have recreated your results using the following steps:

• Record the speaker output using WASAPI
  
• Export the file to a WAV file
  
• Open the saved file
  
• Amplify +50db
  

The result is a significant amount of noise and the spectrum analysis has the same shape as yours.

I have also recreated the result using these steps:

• Generate 30s of silence in Audacity
  
• Export the file to a WAV file
  
• Open the saved file
  
• Amplify +50db
  

Conclusion: The sound you see is generated by the algorithm that saves the file. The sound you hear is generated elsewhere, probably typical line noise.

As proof, try recording your speaker output and before saving apply amplification. If you are using the latest Audacity you will get a value overflow error b/c it can't handle amplifying complete silence. If you have at least one non-zero value in the selection, the amplification works.

Update 2

Further proof: Try saving your recording as 64 bit raw data, and then importing it again. For me this results in a file with no noise, that cannot be amplified again.
