I just got a new harddrive in my computer and it's had a few crashes but now seems to be fine. The only small problem I'm left with is the "Fn + (up key)" and "Fn + (down key)" functions do not work (which before would make the volume go up/down.) The functions that are "Fn (left or right)" still work by making the screen darker/brighter. I tried to install the realtek sound driver from acer and that didn't work. I can't find a solution that works for me. Is there a simple way to check or have it completely uninstalled then reinstalled?
Edit: It's a windows 7 acer aspire 5552 triple core AMD (It was 32-bit before, now it is 64-bit as that was the only option they had to fix it cheaply)
