Unit 4: Systems Troubleshooting — Short Questions

System Troubleshooting is a vital skill for keeping computers, machines, and other equipment running smoothly.

Troubleshooting is essential for maintaining the smooth operation of systems, whether they are computers, machines, or other types of equipment.

A systematic approach to troubleshooting involves the following steps:

• Identify Problem
• Establish a Theory of Probable Cause
• Test the Theory to Determine the Cause
• Establish a Plan of Action to Resolve the Problem
• Implement the Solution
• Verify Full System Functionality
• Document findings, Actions, and Outcomes

Troubleshooting is very important in computing systems because it helps keep our computer, software, and networks running smoothly.

If a printer is not working properly, troubleshooting might reveal a simple paper jam that can be fixed easily, rather than needing to replace the entire printer.

Following are the basic hardware related issues:

• Cable Disconnection
• Overheating
• Peripheral Devices

Issue RAM Failures
Common sign of RAM issues includes frequent system crashes, Blue Screens of Death (BSOD) and poor performance. The computer may also fail to boot or restart randomly.

Solution RAM Diagnostic tools
Use built-in tools like Window Memory Diagnostic or third-party application like MemTest86 to check for RAM issues.

Issue Hard Drive Failures:
Symptoms of hard drive failures include strange noises (like clicking), slow performance, frequent crashes and corrupted files. The computer may also fail or boot or display error messages about the disk.

Solution Hard Drive Diagnostic tools:
Use tools like SMART (self-Monitoring, Analysis, and Reporting Technology) status checks, or software like Crystal Disk Info, to monitor hard drive health.

To upgrade RAM, first determine the type and maximum capacity your motherboard supports. Purchase compatible RAM sticks, power of your computer, open the case, and insert the new RAM into the empty slots.

Example If your computer slow while multitasking (running multiple applications at a time), adding more RAM can help improve its performance.

To replace a hard drive, back up your data, purchase a compatible drive (that can work in your computer), power off your computer, open the case, disconnect the old drive, and connect the new one. After installing the new drive, you will need to reinstall the operating system and restore your data from the backup.

Example If your hard drive is failing, replacing it with a new one can prevent data loss a restore your computer's functionality.

Keeping your computer's storage clean by deleting unnecessary files is like making space in your room. The more organized your files are, the faster your computer will run just like a tidy boy room is easier to navigate.

Software maintenance is an important procedure for ensuring a system's long-term performance, security, and usability after it is released. It includes four types of maintenance: corrective, adaptive, perfective, and preventative. Keeping software up to date and resolving a conflict is essential for security and performance.

Use a combination of upper (A-Z) and lower-case (a-z) letters, numbers (0-9), and special characters (_, $, %, &, *, @, etc.) to create strong passwords. Change passwords regularly and use a password manager to keep track of them.

Management of storage space is one of the key requirements for data management. It is important to keep your computer running smoothly and efficiently.

Computers can overheat if their cooling systems fail. High temperatures can reduce a CPU's lifespan by up to 50%. Proper cooling and regular cleaning can significantly extend a computer's life.
