I have a:

Dell d600 Petium M 1.6 XP PRO
ATI RADEON 9000

Saturday, I downloaded Age of Empires III trial. After installing, I ran
the program and an error message popped up stating that I didn't have the
necessary processor speed to run the game. It said my processor was running
at around 500 Mhz (a high reading was just below 700 Mhz and a low reading
was just above 300 Mhz). I thought that because it was a trial, they hadn't
worked out the kinks. Yesterday, a friend lent me Star Wars Republic Comando
and I received the same message. I called Dell support and after running a
couple of tests, the gentleman I spoke to said, that I was running at my 1.6Ghz
and there was nothing he could do.

I've run several other games (Doom 3, Knights of the Old Republic, Far Cry)
with no problems.

What is it about AoE III and SW Republic Comando that is preventing me from
playing these games? Are there processes running in Media Edition that are
causing conflicts?
