Before I say anything, let us make something very clear. To sum up, do this.
1. Start --> Control Panel --> Performance and Maintenance --> System --> Advanced Tab --> Under Performance click Settings.
2. The following are the ONLY boxes that should be checked: The last one, the second to last one, the third and fourth from the bottom.
3. Click The Advanced Tab --> At the bottom, click Change.
4. There are two white boxes where you can enter numbers. In the first box which to the left says, "Initial Size (MB)" enter 744.
In the second box, which to the left says, "Maximum Size (MB)", enter 1488.
5. Click OK, OK.
What we just did was disable a lot of features you will never notice. Such as: Shadows under Menus. They use system resources,
which you want to save for other programs.
