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.
Troubleshooting 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. 3.
Troubleshooting 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.
Troubleshooting Serial Port The serial device (modem, printer) doesn’t output anything or is outputting garbled characters. 1. Make sure that the serial device’s 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.
