Hi, i am trying to fix a pc, it is a Packard Bell ixtreme Z839. It has been formated and loaded with Win Xp home, after Serice pack 2 is installed it freezes at the windows splash screen and will not boot. I have downloaded the recovery boot disc from the support page, booted to it and entered the serial number,it then asks for the master disc 1, the owners did not recieve any master discs or a windows cd, the version of win xp home was perchased seperatly. I thought the recovery setup was partioned onto the hard drive, but with this one im not sure. If i can preform a low level format on the hdd will it remove the Packard bell software that is causing the problems? or is there somthing on the MB? please help.
