I think I may have thrown the baby out with the bathwater... I've been systematically upreading and replacing components on my PC for the last couple of years. I started w/ a MB/chipset, and got an OEM winders xp pro w/ it. replaced case/ps, gc, sc, network, cd rom, and finally, the HD. When I tossed the case, I couldn't get the id sticker off, so I copied down all the info, and archived it. Well, when I went to swap out HD's, I wanted a clean install of XP, so I decided to load it fresh rather than ghost over. Long story.. err, well, I can't seem to find my XP install CD. Standard retail pro versions won't accept the cd key. Is there such a thing as a replacement install disk? I dont' want or need a product key, I have that. I just want to get what I paid for onto something else that I paid for. PS- while I still have the other HD, its pretty corrupted and ancient, so its in a HD graveyard till another PC recycling day comes up. So, is there such a beast?
