i'm using packard bell esaynote mx37 and i updated from vista to windows 10. now the sound is horrible. i think the video card driver is outdated because when is a video playing is 100% worse. pls help.
Have you tried updating the drivers? Both the Sound and Video ones.
Also, it could be that the laptop may not be able to handle the 'strain' of running Windows 10. Depending on the components.
And, be sure to keep an eye on the laptops temps. There are quite a few programs you can get and install (Speedfan is a good one) to monitor the temps. High temps could be leading to your sound issues and more.
