My laptop was running slow, so I wanted to perform a clean install of windows. I booted from my USB, formatted my drive and then the installed windows. Then, I went to a website called driver solutions something like that, to install drivers. After I restarted my laptop I couldn't use my touchpad nor keyboard, so I wanted to perform a clean install again. When I entered the installation they weren't working again, I tried external but they didn't work neither. Please Help!
