POP:SOT won't acknowledge admin rights

Question

I'm a newbie here and I came to this specific forum because I thought it was the best fit for my problem.  If any one here can suggest a more appropriate place to be for the problem described below I'd appreciate it.  
I bought the game Prince of Persia: Sands of Time but
after installing it and trying to run it a Windows error
pops up saying I must have admin rights to run.  Then
another error says the game process has been manually
killed.  The thing is I'm the only user on the machine
with admin rights--in fact I'm the only user on the
machine period.  Here's what I've tried to correct the
problem, just so anybody willing to help can see what I
may have missed while doing so:
--Uninstalled POP:SOT and cleared out the windows\temp
folder as well as all registry references before
reinstalling
--Installed on the builtin administrator's account
--Installed and rebooted before trying to start program
(even though it didn't say it had to be rebooted)
--Created a new admin account and then tested all of the
above
I've made sure that all antivirus software was turned off
during the installations, and searched other forums as well as whatever relatable issue I could think of on the internet.  Even ubisoft support couldn't help.  I don't know of what else to try.
 All the drivers have been updated and
windows updates have been downloaded & updated as well.  My
machine specs are below if anyone finds them useful.

What could be the problem?  I'd greatly appreciate any
advice

Answer 1

O.K.   I've installed the game on another computer with windows 2000 and it works.  I was relieved to know that it wasn't the game that was bad, but got pissed since it means that it's definitely something with my computer.  I've also made sure that all the registry settings which relate to prince of persia give my users full control within the permissions.  Anyway, here's a list of my IRQ devices:
