I have had this issue before and mine was always unstable even after I got XP to finally load on PC. The CD drive I was using was part of issue it was not good so it would stop spinning while loading OS. U may consider that hardware failure can be to blame on either CD drive or floppy. Why floppy...shouldn't you be able to load ME from CD alone? Maybe change Bios to look at CD first when booting.
Not too familiar with ME..Avoided it too!
What was on this PC before?
