text: computer boot problem!? it doesnot happen often, but sometimes when i boot my computer, it freezes in midway. the mouse won't move. what might be the problem and the solution? problem is definately the hard disk. bad sectors must have developed on the storage media in the hard disk  this normally happens due to shutting off the pc directly or by cutting the power supply without going to "start" and turn off computer option. this reduces life of a harddisk. run scan disk at startup to mark the bad sectors on the harddisk so that data is not stored in already marked bad sectors.
