Original Title: Windows 7 boots to black screen with cursor before login screen, nothing works
I turned my computer on yesterday to find that, after the Windows loading screen, everything went black. The cursor is there and will move around, but right clicking does nothing, Ctrl-Alt-Del does nothing, safe mode does nothing, system restore does nothing, startup repair does nothing, sticky keys does nothing, absolutely nothing on earth will get me to the login screen. I've tried every solution on every website I could find and none of them did anything.
If it helps, I was tooling around with ownership of the System32 file before this started and, well aware of the inherent risks, I transferred ownership of the folder to myself so I could replace ONE DLL with a newer version. The name of the DLL is dwmapi.dll. Then, after turning off my computer, everything went to black. What should I do?
