Okay, as the title says, I upgraded. But there's a problem: Nothing on this OS seems to be working. Explorer.exe constantly crashes, and a couple of hours ago, the computer itself just froze entirely, with me not even able to do ANYTHING. I fixed the freezing by updating my graphics drivers, but there's still so many problems. Sometimes while booting, it will be completely black, but my cursor is still there, so I have to manually go into task manager to open explorer. Even now, none of the icons on my taskbar work. Sometimes they highlight like normal when hovered over, but when clicked they do nothing. The only way I can get into anything is to click on a folder on my desktop, and navigate to the app I want that way. My computer is over twice as slow as it was before, even though right now I'm only doing very simple things, like navigating through folders. And just now, while typing this, my computer bluescreened, with the error "Critical Process died" I really need some help right now. I use my computer pretty much all day, and kind of need it.
