|Are the CD's that you are using original installation CD from microsoft or a copy of or a restore disc deom a manufacturer of computers such as Dell or HP?|
Did you check to see if there was a restore partition set up on the drive to be used for doing such...or was it that you just jumped in and started using the installation CD's.
Is the COA license that is attached to the computer the same type as the installation CD you are trying to use....would hate to see that all your work is for nothing when you can't activate because it is wrong.
XP has always had a major issue with hardware that was pre-installed in a computer....remove the extra hardware and then see if it will install. take out any extra memory sticks, extra drives...including hard drives and optical drives that are not required for use during set-up and installation. Make sure the BIOS is set to default settings and not overclocked (which a lot of manufacturers pulled in making customers believe they had a faster computer)
Make sure that you are using only one installed video adapter. Remove any network cards and disconnect from the web until after the installation.
Change Is Good
