Performance Problems
For best performance with Windows 2000, your computer should have at least 96 to
128 MB of memory (RAM).
If the computer pauses or runs sluggishly
• This may be normal Windows behavior. Background processing can affect response
time.
• Certain background operations (such as VirusScan) can affect performance.
• Press CTRL+ALT+DEL to see if an application is not responding.
• Restart the computer: click Start, Shut Down, Restart.
• Some file browsers respond slowly while processing graphics or waiting for broken
network connections to time out.
• If the computer’s hard disk drive frequently runs (as indicated by the hard drive light
on the front of the computer) while the computer appears to be paused or running
slowly, Windows is likely spending excess time writing to its swap file on the
computer’s hard disk. If this occurs frequently, consider installing additional memory.
• Check the amount of available free disk space. Delete temporary and unneeded files.
• Check settings in the BIOS Setup utility:
1. Click Start, Shut Down, Restart.
