When we turn this machine on,
The error is always bring with "Preparing Automatic repair" and "Diagnosing your PC"
When i restart machine "it said, your pc ran into a problem and needs to restart"etc...
These error are same thing!
What should i do?
Press F8 when windows is booting up. Select safe mode. Once you are in windows, see if you can restore the system back to a previous state.
If you don't need any information from the computer-you can always restore the machine using dell restore software
