At last use, it was turned off as normal by clicking on 'turn off computer' and as far as we know it shut down as normal.
When we start the laptop up we are faced with the black screen which asks if you want to start the computer in safe mode, safe mode with command prompts and to start it at the last good configuration etc.
When I have asked to start the pc both in safe mode and safe mode with command prompts the file paths scroll down the screen and thats it.
When opting to start at last 'good' configuration the initial windows startup begins then it flashes a blue screen, too quickly to read, and then goes back to the initial screen with the safe mode options. It then starts the same process again every 30 seconds.
