Troubleshooting a Screen Freeze in Windows 2000 Professional
- When all of your computer's memory is being used, no other resources are available to run programs or services. This can occur when all of the physical memory on the system is being used. The screen will appear to freeze until more memory is available. Your system uses virtual memory, but this will not help if all of the physical memory is being used. You can prevent the system from using all of the available RAM by monitoring running programs or adding more RAM.
- When you are running multiple programs at once, you run the risk of using all of the available system resources. You might also be running programs that are extremely memory intensive. This can include video processing and burning a CD. Screen freeze can usually be prevented when you are not trying to use multiple programs at once. You should at least wait until one process is done before attempting to use another. Keep in mind the number or open programs affects the amount of memory and resources being used.
- You might have programs running that require a great deal of processing power. You might also have a program that is "stuck" utilizing 90 percent or more of your system's processing capacity. When this happens, your screen will freeze because there isn't any spare processor capacity to continue with other tasks. You can use the Windows "Task Manager" to see the current processor usage for your Windows 2000 Professional system. Press the "Ctrl," "Alt" and "Del" keys at the same time to access the "Task Manager." If the processor usage is too high for one or more programs that are not being used, they can be terminated.
