Toshiba New Hard Drive wont load Xp Pro, Vista, Window 7

Hi out there. I have a Toshiba L305 Laptop which I tried to upgrade the HD from 160GB to 500GB but I get the BSOD message saying to protect my computer Windows cannot load due to a software and/or a hardware change. I called Toshiba and the phone operator barely understood English too well and all the options he gave me involved a call to TechSpt and charge me $139.99 to assit me in loading the OS , I declined given, this an issue with many people to fix this problem. Any and all assistance would be greatly appreciated, Many thanks, Audie Milligan Aguirre
