I boot up my PC one friday night. Click my icon, start typing, but nothing happens when I click login. I go off and drink a soda, come back some time later, nothing happened. Reboot, same result. Rolled it back in safe mode, and then the same result. This is why I now use a Raspbian computer, a Windows 7 laptop, and my Windows tablet.
Yeah, I quit using it and it hasn't been used since. It's gathering dust under my bed atm.
