Many people are faced with computer problems that are easy to fix on a daily basis, but are unable to make a real diagnosis of the problem. Although the problems encountered in a computer are many and of different nature, this article will explain how to deal with the most common problems.

Steps

Step 1. Check the Power On Self Test (POST)

This is usually the first or second thing that appears on a computer after it is turned on, before the operating system loads. The POST will display any hardware problem that makes it impossible to start the computer; it can also show hardware issues that allow the computer to start, but prevent it from working to the best of its ability during the operation.

Step 2. Check the operating system load time

If it is longer than usual, it may indicate hidden errors in the hard drive.

Step 3. Check for graphics problems once the operating system has loaded

Reduced graphics can indicate a lack of drivers or hardware issues with the graphics card.

Step 4. Take a hearing test

It's unorthodox, but it's still an effective way to gauge how hard the computer is working. With your computer running and running, listen to a fairly long audio file (usually around 30 seconds). If the audio is slow or limp, it usually means that the processor is running at a high level or that there is not enough RAM to run all the programs that are loaded. Change the startup sound strategically in order to apply the test. Another problem associated with variable sounds is inherent in the PIO MODE (Programmed Input / Output). This affects the way the hard drive writes and reads data from the drive. Changing it to DMA allows for faster reading and writing and sometimes puts an end to the limp audio.

Step 5. Check all newly installed hardware

Many operating systems, especially Windows, can conflict with new drivers. The driver may be badly written or conflict with another process. Windows usually notifies you about devices that are causing a problem or not working. To control them, use the Device Manager: you can call it by entering the Control Panel, clicking on the System icon, Hardware window and selecting Device Manager. Use it to check and fix hardware properties.

Step 6. Check all newly installed software

The software may require more resources than the operating system provides. It is likely that, if a problem starts after starting the software, it is the latter that causes it. If the problem appears directly at startup, it may be due to the software that starts automatically.

Step 7. Check RAM and CPU consumption

A common problem is that the system is unstable or sluggish. If the system is unstable, it is good practice to see if the program is consuming more resources than the computer offers. An easy way to check it is to use the Task Manager: right-click on the taskbar, select Task Manager and click on the Processes tab. The CPU column contains a number that indicates the percentage of CPU that the process is consuming. The Memory Usage column indicates how much memory is being used by the process.

Step 8. Listen to the computer:

if the hard drive is crackling or making loud noises, shut down the computer and have the hard drive done a professional check. Listen to the CPU fan: It is at high speed when the CPU is working hard and can warn you if the computer is working beyond its capabilities.

Step 9. Scan for viruses and malware

Yield problems can be caused by malware on your computer. With a virus check you can find any problem. Use an antivirus (like Norton or Avast!) And a malware scanner (like Spybot Search & Destroy) that are constantly updated.

Step 10. Check for the problem in Safe Mode, as a last resort

To enter this mode, press the F8 key repeatedly during the POST phase (this works on most systems). If the problem persists in Safe mode, it is almost certainly due to the operating system itself.

Advice

  • These procedures identify the most common malfunctions, but to find a specific problem it is best to use specialized tools or techniques.
  • If you are not comfortable diagnosing or repairing a computer problem, it is best to take it to a certified technician and have it repaired at an acceptable cost.

Warnings

  • Do not attempt to fix problems if you are unsure of what you are doing, what the outcome will be, and any adverse events that may occur.
  • Always consult a competent technician, whether you intend to do the check yourself or you do it under supervision.
