For 2 or so days now my sisters laptop has been having problems with Windows Explorer repeatedly crashing for no apparent reason. Have not tried anything to fix problem yet as do not know where to start. As soon as the laptop is logged in, explorer starts crashing & when it reboots it crashes again. Laptop is Windows XP and so far to my knowledge no new programs or files have been installed, will post new information as I find out. Need urgent help as laptop is needed for assignments.
