I have a fairly new Toshiba computer with windows 8/8.1 preinstalled on it. Windows hasn't been working correctly since the purchase so I reinstalled windows from the drive and I have had problems activating windows since then. When I select activate windows either from the system page or the pc settings page I get a blank screen then it goes back to the start menu.I have tried to reinstall windows several times trying to get it to activate automatically like it's supposed to but I have not been successful. Even if I had a key to put into the activation screen I would not be able to use it because my windows activator isn't working correctly. I have listed some of my system let me know if any other info is needed. Thanks
system type: 64-bit operating system, x64 base processor
edition: windows 8.1
activation: windows is not activated
Manufacturer: toshiba
