Chapter 4 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. The power switch of each peripheral device is turned on. 2.
The picture seems to be constantly moving. 1. The monitor has lost its vertical sync. Adjust the monitor’s vertical sync. 2. Move away any objects, such as another monitor or fan, that may be creating a magnetic field around the display. 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. Fluorescent lights adjacent to the monitor may also cause screen wavering.
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. Excessively long formatting period. 1. If your hard drive takes an excessively long period of time to format, it is likely a cable connection problem. Parallel Port The parallel printer doesn’trespond when you try to print.
3. Verify that the attached serial device works by attaching it to a serial port that is working and configured correctly. If the serial device does not work, either the cable or the serial device has a problem. If the serial device works, the problem may be due to the onboard I/O or the address setting. 4. Make sure the COM settings and I/O address are configured correctly. Keyboard Nothing happens when a key on the keyboard was pressed. 1. Make sure the keyboard is properly connected. 2.
