Hi there, \r\n\r\nI wonder if anyone can help me with following. \r\n\r\nI am using Dell Inspiron 6400 laptop. It was 1st time rebooted about 6 months ago after few years of purchase. After reboot, it was working fine. \r\n\r\nHowever, 2 days ago I switched off at night as normal and when I switched on in the next day morning, I were shocked to see laptop was excatly in new mode (it was automatically rebooted and came into blank mode due to which I lost all files which were in desktop and my documents). After spending sometimes, luckily, I managed to find find back up in C:local disk. But again, yesterday I switched off in the night and switched on this morning and again laptop came back to blank and rebooted mode and lost all files which I could see yesterday. I am really worried as I have had all my course work from university. Can anyone help how to locate these files and how to stop this happening with laptop. \r\n\r\nThanks in advance for great help.
