Does it always reboot at the same place, or does it sometimes go into Windows and sometimes doesn't?
If it reboots at exactly the same step all the time, it's probably software related. Boot off of the Windows CD, repair Windows, type in chkdsk /p and let it run, exit then reboot. If it still does the same thing, your userinit.exe is corrupted. Replace it from the i386 folder and try it again. Worse comes to worse reinstall Windows again, since you just did it recently you probably won't have a lot of data to lose.
