Go to Microsoft and get a copy of Windows 8.1, Burn it to a DVD or Use the USB option to get your PC back up and running. You will have to provide the COA Key from the sticker on the bottom of your laptop in order to download it.
I don't know where you are getting your drivers from, but I suggest only getting the drivers from Acer Support. Also Windows should install most drivers from Windows Update.
Here is the link to the Microsoft Windows 8.1 Download page of their site.
