Ok so I noticed my PC was being slow recently like it can't do anything it freezes doing actions and it would never open Task Manager. So I thought I would reboot and launch Task Manager right away to see what's going on. While I'm monitoring nothing happens until 5 minutes later my cursor had a loading symbol and Task manager was slowly using up my memory. It just kept going up and up and then the freezes started to happen. I am confused what is going on but it started happening and I had other problems before hands like Power Kernel resets which someone said it could be a software issue since it doesn't blue screen it just starts up again. I am using Windows 8.1 and these problems started happening when it told me my win key is expiring. I don't have a legit copy either :/ is a format needed?
