Hey Guys...

So my Packard Bell Easy Note MX37-S-200 has suddenly started making persistent " Crackling " and " Popping" noises from the moment i boot it. The noise is coming from the speakers and the sound is now distorted. I have very recently got it back from the repair shop after having my AC jack replaced... I would really like to rule everything out before i start pointing fingers at the repair guy smile.gif

Things i have tried - Disabling sound driver - Noise was still there and laptop just installed it again.

Running avast scan through it - Scan picked up nothing.

Played with the sound setting - Nothing changed noise still there.

Plugged in PC speakers - Noise still coming from laptop but sound came out of the speakers fine.

 

I have noticed also that when the laptop first starts up the noise is louder and more spaced out. I'm wondering maybe whether it is the fan? But i don't no why the noise would be coming from the speakers.

 

Would really appreciate any help
Thank you smile.gif

First of all, welcome to BC !

 

As a former electronic repair tech, one of the basic principles of repairing things is very similar to one of the Hippocratic Principles  of medicine - "First do no harm !".

 

You have checked the obvious things - take it back to the repair shop and jump up and down, politely. It wan't doing this when you took it in, and now it is.

PS :-  You always start off politely, you can get more positive later. Doing it the other way round is never convincing !

Did you disable the sound driver or did you uninstall it?

 

This had happened to me once, for some reason when I installed windows 7 on one of my computers, windows installed the wrong sound driver. For me the solution was to uninstall the driver, reboot (upon reboot, no sound card was detected). However, when I went to the windows update, it did detect my sound card and it did download the right driver. I had to reboot and everything was fine.

 

Please do a new system restore point first before you try this.

 

Thanks
