About System Resources
Windows 95, 98, and Me has a special area of memory called system resources that keep track of important information for user interface items such as windows, icons, buttons, menus, and toolbars. The system resources memory area is a fixed size, and does not get bigger no matter how much main memory you install. A system with 32MB of memory has the same size resource area as one with 256MB of memory. (Windows 2000 and XP remove this limitation.)
Each application you run requires some of those system resources. The more applications that you have running, the more system resources you will need to use. The amount required by an application can vary widely; some need only 1 or 2 percent, others need 10 or 20 percent. When free system resources drop below 20 percent, Windows can start to behave strangely. You may get error messages, crashes, or programs just quietly refuse to open dialogs or windows. For some resource-hungry programs, resource-related problems can occur at even higher-levels of free resources.
Solutions
If your system supports it, upgrading to Windows 2000 or XP will eliminate the system resources limitation. If you stay with Windows 95, 98, or Me, we recommend that you try to keep free resources above 40 percent. To check your PCs current value for free resources:
Select Start | Control Panel | System
Click the Performance tab.
A freshly booted Windows system with nothing running should generally have 80 percent or more of its system resources free. If your number is significantly lower, it is usually due to applications that have been started automatically. See the windows details page for a list of programs that were running during testing. Use the MSConfig program to change startup programs, see our instructions for more information.
If an application crashes or it is not programmed correctly, it may not return all the system resources when you close it. This is called resource leakage. There is no easy way to recover leaked resources; you must reboot the PC to get them back.
