User profiles deleted on start up

Hey guys every time i restart my laptop it wipes all the user profiles, leaves one and wipes all the custom settings on that profile. I have no idea and any help would be greatly appreciated

Thanks again

This might be caused by a virus or other malware infection, a corrupt hard drive or Windows itself is corrupt... Can you do a destructive laptop restore? This is a way that the laptop is put back just like it was when you turned it on when you first bought it
