what PSU do you have?
also make sure the CDRom is pinned to master, have it on IDE1, set the BIOS to boot from CDROM, have your floppy ready with the sATA drivers just in case the install CD does not have the drivers for sATA2 as that is what your HDD is.
so in order:
1. verify that your PSU is nothing less then an Antec True Power 2 550W, or better
2. verify that your CDROM is pinned master
3. verify that your CDROM is cabled to IDE primary (normally that is the blue one, but meh every MB maker is different)
4. check the CD for scratches, clean if need be, replace if can.
5. have floppy with sATA drivers for winXP
6. REMOVE all peripherals other then video BEFORE installing. this will cut down on power consumption if the PSU is an issue this could help. also if you are running SLI/Crossfire, remove 1 of the 2 vid cards and install with just 1 (ONE) card.
7. swap out the CDROM with a known working drive. i have had instances in the past were the CDROM was just bunk and would not install an OS, or some applications. so as you have older comps still around, as you are posting from them, use one of those laser drivers for the install.
repost when done.
