Vista - Vista install aborts with: SPWIZENG.DLL + autorun.dll errors

I purchased Windows Vista Ultimate through microsoft and tried to install it
last night. Left it running all night, and it pretty much rebooted
repeatedly during a "clean" install, including a reformat. I reattempted the
process by re-installing my copy of XP Pro, fully updating it, and then
trying the Vista update feature. Each time I get either the SPWIZENG.DLL
error that is then followed by the autorun.dll error, or just the autorun by
itself. Odd thing is, I had to reinstall drivers in such and the autorun
preforms just fine with all other DVDs/CDs. Heck, I even tried video game
just to be sure and it booted fine. I noticed that this problem was
mentioned once before, but no answer was given. That I'll have more luck
.. Thanks in advance.
