Run your game at the lowest possible settings. If that don't work, buy a new graphics card (You can get one that can run PSO widescreen for about 40-80$) or PC. If your laptop has a shared memory between the on board graphics and CPU, then a RAM upgrade will help.
Start > Run > type "msconfig" and hit enter. Choose startup. Uncheck any stuff you don't want to start with windows. Save and reboot. That should free up some ram.
Laptop ram is cheap. Buy more. On most laptops it is very easy to upgrade.
