i hate these random problems too!
well, my suggestion would be to try XP again, if it still hangs, try using win2k.
if win2k works, perhaps your xp media isnt working, or just something is fishy with the driver configuration of the mobo with the xp install... you can then just try to upgrade to XP if you want it.
if win2k doesnt work, then at least you know there is a better chance that it is a hardware problem...
this is all assuming that u want to use NTFS. i dont imagine changing the file system would cause the OS not to install, but i could be wrong.
in any case. i hate these random problems! but at least they build skillzzz... hahaha 😉
good luck 😉
