Computer problems can be attributed to hardware, software, networks, or some combination of the three. You will resolve some types of problems more often than others. Common hardware problems include the following:
- Storage Device - Storage device problems are often related to loose or incorrect cable connections, incorrect drive and media formats, and incorrect jumper and BIOS settings, as shown in Figure 1.
- Motherboard and Internal Component - These problems are often caused by incorrect or loose cables, failed components, incorrect drivers, and corrupted updates, as shown in Figure 2.
- Power Supply - Power problems are often caused by a faulty power supply, loose connections, and inadequate wattage, as shown in Figure 3.
- CPU and Memory - Processor and memory problems are often caused by faulty installations, incorrect BIOS settings, inadequate cooling and ventilation, and compatibility issues, as shown in Figure 4.
