Study Notes
Common PC Problems and Solutions
- Common computer problems can be diagnosed and solved using various methods
Diagnosing Startup Problems
- The Power On Self-Test (POST) displays hardware problems that prevent the computer from booting or operating at full capacity
- A longer than usual load time of the operating system may indicate errors in the hard drive
- Graphics problems after loading the OS may indicate driver failures or hardware failures with graphic cards
Auditory Test for Computer Performance
- Playing an audio file can help judge the computer's performance
- Choppy or slow audio may indicate the processor is working at an elevated level or there is not enough RAM
- Switching to Direct Memory Access (DMA) can repair choppy audio and allow for faster reads and writes
Troubleshooting Newly Installed Hardware and Software
- Newly installed hardware may conflict with the operating system, especially Windows
- Use the Device Manager to check and arrange properties of hardware
- Newly installed software may require more resources than the system can provide, causing problems
Checking RAM and CPU Consumption
- High RAM and CPU consumption can cause problems
- Check for software that starts automatically on boot, which may be causing the problem
Basic Troubleshooting Methods
- Trial and error: test faulty components on other computers to determine the problem
- Check cables: ensure all cables are plugged in and working fine
- Check hardware settings: update device drivers and ensure all cards are plugged in properly
- Identify changes: determine what changed before the problem occurred
- Use the Event Viewer to find error or warning messages associated with faulty hardware or software
- Take notes: record errors and their solutions to learn from troubleshooting experiences
