Internet Explorer was running really slow for the past three months, I didnt think anything of it, I just used Torch. Then my whole computer started becoming slow and "laggy" so I started to uninstall the things that were recently installed (I got my laptop on Christmas 2013) and suddenly it didn't connect to the internet at all, I tried to just hook it back up but it wont find the wireless network, I went to the start screen and it looked like something was missing but I don't know what. I might have accidentally uninstalled something important. I could reset my computer to its factory settings but my dad said that he cant get his friend to download Microsoft on it again. I don't know what to do. Please help.
