General hardware problems
If your computer exhibits one or more of the following symptoms, a device conflict may
exist:
• Your computer locks up, particularly while using a specific device.
• A recently added device does not work.
• Memory parity errors occur on parity-enabled computers.
• A sound card emits noise or demonstrates other problems.
• Unintelligible characters print from the printer.
• The mouse pointer does not move or "stutters" when it moves.
• Messages appear stating that the computer is not operating at maximum performance.
• Errors occur and programs crash for no apparent reason.
• Nothing displays on the monitor.
REMOVE ANY RECENTLY ADDED HARDWARE TO SEE IF IT RESOLVES
THE CONFLICT — If removing the hardware resolves the conflict, see the
hardware documentation for configuration and troubleshooting instructions. If
the problem persists, contact the hardware manufacturer for technical assistance.
