Windows 7: Computer crash without BSOD. Why a loss of only some files?

I apologize if this is not the proper area in which to ask this question, however I could not find another place to ask it.

My computer crashed without the BSOD. When it restarted, everything was reverted back to factory settings.

My brother, who is the computer nerd of our family, looked through my computer and found all the programs to still exist but be uninstalled, and all files moved to Computer > Local Disk (C: ) > Users. I proceeded to reorganize all files (Documents, Pictures, Videos, Music) into their usual Libraries.

The next time I turned on the computer, everything reverted back to normal except for the pictures. All of the ones I uploaded had disappeared.

I'm confused as to why. I treated them the same as I did all other files - which all reverted back to normal -and yet the pictures did not.

I checked the Users file in Local Disk(C: ) again and nothing was there. I have tried to show all hidden files but to no avail. They are also not in the recycle bin.



Are there any other places they might be? And, is there any commonly known reason for this type of crash?

If anyone has any information regarding these questions, please answer! It would be a great help
