How do I do a clean re-install of Windows XP Home on my Dell desktop pc? Original is years old - pre Service Pack 1 and i'm on SP3. I've backed up all the documents & drivers I can find, but ... when I insert the original XP CD I get a message saying the version on the pc is newer than the one on CD, and it forces me out. Evidently I need to uninstall XP, but ... the advice says to do this from Add/Remove Programs, and XP doesn't appear on my program list. Just XP SP3 and other Windows update-typ-entries. I even went so far as going into BIOS and telling it to boot from the CD but ... all that did was disable my CD drives and network card. My goal is simply to wipe everything off the pc and start clean. Had to resort to System Restore for this. Help!!!!!
