I formatted my girlfriends Packard Bell ALP-AJAX C3 (also known as an Easynote MX52) laptop last night and put Windows 7 on it (as was previous), problem I have is since reinstalling the sound is very crackly, there's only drivers I have are those which Windows update supplies.

It has a Realtek HD sound chip, I have installed the official Realtek drivers from the Realtek website but it's exactly the same, the best I can manage is to use the drivers Microsoft supplies but there is still crackling which appears to be based on the activity of the computer, i.e. dragging a window around whilst an MP3 is playing causes it to distort.

Now seeing as this has worked fine on Windows 7 previously, what on earth is going on? I spent several hours on it last night but didn't actually get anywhere with it.

Crackly at all volumes, the Packard Bell website has no drivers for Windows 7.

Playing an MP3 can be OK, but then if you drag the window around it crackles.

Which doesn't yield anything more than telling me it's Realtek HD, which I already knew, there's no manufacturer specific driver.
 
Got her to reinstall Windows again and not install any drivers bar the ones Windows does and it works, confused.
 
I'd already thought that might be a problem wozzsta but thanks for confirming.
