Troubleshooting B Appendix B - Troubleshooting B.1 Troubleshooting Checklist This chapter of the manual is designed to help you with problems that you may encounter with your personal computer. To efficiently troubleshoot your system, treat each problem individually. This is to ensure an accurate diagnosis of the problem in case a problem has multiple causes. Some of the most common things to check when you encounter problems while using your system are listed below. 1.
B Troubleshooting The picture seems to be constantly moving. 1. The monitor has lost its ver tical sync. Adjust the monitors vertical sync. 2. Move away any objects, such as another monitor or fan, that may be creating a magnetic field around the display. 3. Make sure your video cards output frequencies are supported by this monitor. The screen seems to be constantly wavering. 1. If the monitor is close to another monitor, the adjacent monitor may need to be turned off.
Troubleshooting B Hard Drive Hard disk failure. 1. Make sure the correct drive type for the hard disk drive has been entered in the BIOS. 2. If the system is configured with two hard drives, make sure the bootable (first) hard drive is configured as Master and the second hard drive is configured as Slave. The master hard drive must have an active/bootable par tition. Excessively long formatting period. 1.
B Troubleshooting Serial Port The serial device (modem, printer) doesnt output anything or is outputting garbled characters. 1. Make sure that the serial devices power is turned on and that the device is on-line. 2. Verify that the device is plugged into the correct serial port on the rear of the computer. 3. Verify that the attached serial device works by attaching it to a serial por t that is working and configured correctly.
