I use a PC with Win7 professional 64 bits.
It is in a network. I do not have the Admin privileges.
It boots up with normal screens and after login remains blocked in a black screen where only the mouse I can move and only the task manager works. Windows explorer does not start even if I “force” it with “New Task”.
The same black screen appears even if I am in Safe Mode.
I can start in command prompt mode and I run chkdsk. It says that runs as Administrator. Now is running and will take 3 hours.
Any suggestions of how to debug further?
