OK I have all the hardware I have my old gaming computer formatted what software do I need? I have copies of windows 98,me or xp I can put on the computer. My new computer uses vista but I'd rather not use my new one just in case something gos wrong. Is there any good free were out there or something not to pricey that's easy to use?
