This is in the wrong area, moving to the correct area.

From what I can see there you need more memory and a new graphics card.

I would have to agree with Leonardofury.

Your memory is at the minimum recommended for XP, you really do need to at least double that.

The SiS graphics chip really won't be able to handle the graphics for RCT3 well at all. Even with the graphics set to the minimum level in the game. You should upgrade to an ATI Radeon with at least 128 MB of RAM. You can find these cards for as little as $50.

With the system you have now, I wouldn't recommend trying to play RCT3 prior to upgrading.
