I see you say "almost everything has stopped working including the drivers ( mainly )". That could possibly explain everything you're seeing. Please describe what you did when you switched hard drives regarding how you got Windows installed.
The way I would've done it would've been to back the HD up to an external hard drive, switch the HDs, then restore. Another way would be to use the discs that came with the computer to restore to factory settings. However I suspect that you did something different from this. Right?
Greetings everyone i'm all new here
So basically i have this kinda big problem that's followed by a pretty long story, please if you can take a few minutes to answer this i will be hugely thankful.
A while ago i changed my laptops 320GB hard drive disk ( hdd ) with a 160GB one, then i knew that it's definitely not enough for the laptop to actually run on windows 8, so i moved to windows 7. Since then, almost everything has stopped working including the drivers ( mainly ), some features, keyboard buttons etc. Then i switched back to my 320GB hdd but absolutely nothing has changed, so i figured out that it has something to do with windows 7. Now the thing i really want to know is what would happen if i change back to windows 8? would it make my laptop work properly again as it was before? i don't want to waste money unless i'm perfectly sure. I would be EXTREMELY grateful for you guys if you could at least recommend anything that would bring my laptop back to life!
P.S : When i made the first change i formatted the 320GB hdd unfortunately :/
