After the system has been running correctly

Problems that occur after the system has been running correctly with no hardware or software changes often indicate equipment failure. However, recent changes made to the system, such as hardware or software that has been added or removed, might also be the source of the problems. Check the following:

•If you are running the software from a diskette, try a new copy of the software.

•If you are running the software from a CD-ROM disc, try a different disc to see if the problem occurs on all discs.

•If you are running the software from a hard drive, try running it from a diskette. If the software runs correctly, there might be a problem with the copy on the hard drive. Reinstall the software on the hard disk, and try running it again. Make sure all necessary files are installed.

•If the problems are intermittent, there might be a loose cable, dirt in the keyboard (if keyboard input is incorrect), a marginal power supply, or other intermittent component failures.

•If you suspect that a transient voltage spike, power outage, or brownout might have occurred, reload the software and try running it again. Symptoms of voltage spikes include a flickering video display, unexpected system reboots, and the system not responding to user commands.

If all items are correct and problems persist, contact your service representative or authorized dealer for assistance.

Monitoring POST

When you turn on the system, POST displays messages that provide information about the system. If a failure occurs, POST emits beep codes that indicate errors in hardware, software, and firmware. If POST can display a message on the video display, the speaker beeps twice as the message appears. For a complete list of errors and codes, refer to page 211.
