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
Learn the basic troubleshooting steps for diagnosing computer startup problems and error messages. Explore methods like trial and error testing of faulty components and checking cables for faults.
