Troubleshooting Your Computer
114 Reference Guide
If a PC card modem is not working
• Disable the internal modem:
1. Open the hardware Device Manager: click Start, Settings, Control Panel, System
(Windows 98 or 2000) or Start, Control Panel, Performance and Maintenance,
System (Windows XP).
2. Double-click Modem to list the current modem devices.
3. Double-click the internal modem, then select the option to disable the modem.
If an I/O card stops communicating properly
• Exit and restart the application. The card may have been reset if the computer
suspended or turned off.
• Check settings in Control Panel.
Performance Problems
For best performance with Windows 2000 or XP, your computer should have at least
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 a virus-scanning program) can affect
performance.
• Press CTRL+ALT+DEL to see if an application is not responding.
• Restart the computer: click Start, Shut Down (or Turn Off Computer), 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.
