I get exactly the same message on my XP Media Center Edition 2005 laptop with nVidia go 7200. It's a HP dv6152eu.
Are you running on AMD's Turion 64X2? I think its this that causes it becasue it doesn't like to run many games. The only game I've got to run so far is Rollercoaster Tycoon 3. Other games have to be runnning in compatibility mode for win98 to work. I think its because the 2 proccessors are running at different speeds. I don't know how to fix this problem though...
