Hard Drive Failure, Windows Not Working

went to get a new laptop and founds a nice mew Toshiba laptop (have to check model number) got the laptop home an started up fine worked fine also got thee system online and with all the anti virus set up (used the 90 day Norton trial) worked fine next day I stared the laptop up and the worked fine for a wile then went into a full crash with nothing responding forced a reboot look fine bios came up vista went to load the bar stuck and then restarted then kept doing this and no hard drive activity left the machine

and still stayed like this tried restore and start-up recovery as the pc was loading in safe mode the laptop did start the reload of the hard drive after that said was successful rebooted and did not want to load up ,took the pc back and checked the machine out they could not fix there machine the man told me the machine was not going to work and sated to fill out a Toshiba doa form stating that hard drive failure was the cause, that left me the option to change the laptop or get my money back and chose the get money back to see what i could get else were still looking I am thinking of getting a Sony vairo instead
