I think I have solved this.
On my motherboard (Nforce 4 Ultra), in my BIOS, under the Power->ACPI
settings, the APIC support setting was set to disabled. Upon setting it to
enabled, and unfortunately doing a re-install (didn't work until I did that,
but your mileage may vary) everything worked perfectly. Apparently Vista
requires APIC to be enabled. Why it was set to disabled, is beyond me (I may
have done this, or it may have been set to this by default).
I hope this helps.
