I absolutely could not do anything. After logging on dark screen. Came only in the Task Manager. Everything else away. And no idea what's going on: Virus? Problem with hardware? For weeks, repeatedly tried to start with new and unsubscribe, had already given up. Then ichs with this disc tried, and it worked. Bin for hours in it, everything back. However, the disc went with me not automatically going on, only with the help and I was not to select your language from the menu or PC repair as is on the disc. He simply reinstalled the Windows operating system, restart and it went. Am super happy.
