[RESOLVED] PC Too Fast To Run Game - Dual Core Problem

[Nix]

Am running a Dell Dimension E521 with

AMD LIVE! Technology - AMD Athlon 64 X2 Dual Core Processor 4200+
Windows XP MCE
1GB (2x512) NECC Dual Channel DDR2 533Mhz SDRAM Memory
256MB PCIe x16 NVidia GeForce 7300LE TurboCache
16x DVDRW Drive.

When I install Harry Potter and the Chamber of Secrets the cinematics play to fast and the spoken dialog gets cut off mid sentence as the next cinematic starts displayed.

Once in the game itself Harry moves around to fast and looks like he is hopping and jumping around quickly.

I tried running in compatibility mode and it just wouldn't run.

I did get some level of succes with the cinematics by changing the minimum frame rate in one of the ini files to 90, but then in the game harry moved like a snail.

I tried it on my work PC also running XP but much lower specs and just onboard video and it works just fine at the right speed (well a decent one anyway).

So, I'm thinking it's because my home PC is too powerful, or maybe because it's dual core ?

Incidentally Harry Potter and the Sorcerers Stone and Harry Potter and the Prisoner of Azkaban both play install and run ok but only after setting their compatibility mode to Win98 \ Me.

Is there some way of temporarily disabling dual core or maybe I need to kick of some process to run in the background using one of the cores.

I googled a bit but just kept getting hits for the movie or game reviews or demos.

The game is under the Electronic Arts lable.
