I have a HP Lightscribe DVDWriter HPDVD 1040 which is on the list of compatible drives. CDBurnerXP is telling me no compatible drives found. I have a Compaq AMD Sempron with Wiondows XP. I read something about installing the newest amd chipset, but am sort of clueless on how to do so or if it would actually help. Any help would be appreciated, please step by step if possible.I tried going to Device Manager and searching for updated hardware like on of the posts said, but nothing changed. Itried uninstalling and reinstalling thinking that maybe I checked somthing wrong, but still nothing.
