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, 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 mucking around with ownership of the c partition before this started and, well aware of the inherent risks, I transferred ownership of the entire partition to myself, which more then likely affected the c:\windows & \system32 folder. Then, after turning off my computer, everything went to black. What should I do?
