Running New Application Software Problems that occur when you run new application software are usually related to the software. Faulty equipment is much less likely, especially if other software runs correctly. Application Software Checklist Does the system meet the minimum hardware requirements for the software? See the software documentation. If you are running the software from a diskette, were the files copied to the diskette correctly? If you are running the software from a CD-ROM disk, is the disk scratched or dirty? If you are running the software from a hard drive, is the software correctly installed? Were all necessary procedures followed and files installed? Are the correct device drivers installed? Is the software correctly configured for the system? Are you using the software correctly? If problems persist, contact the software vendor's customer service representative. 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 disk, try a different disk to see if the problem occurs on all disks. 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, see page 130. 86
