Generally, everyday computer problems can be solved easily once the root cause is identified. This article will show you some of the common sources of computer problems.
Step
Step 1. Check the POST (Power On Self Test) screen that appears when the computer is turned on
On some computers, this screen appears after the manufacturer's logo. The POST screen always appears before the operating system is loaded, and displays problems that occur on the computer when the computer does not turn on properly. Through the POST screen, you can also find problems that are preventing your computer from working properly.
Step 2. Pay attention to the loading time of the operating system
If the operating system does not load by the computer, the storage drive may have an error or damage.
Step 3. Once the operating system is loaded, find the graphics problem
Weak graphics performance may indicate a graphics card malfunction, or a driver error has occurred.
Step 4. Perform an auditory test
As strange as it may sound, this test can determine the load on a computer. While the computer is on, play an audio file of a reasonable length, at least over 30 seconds, or change the startup sound on the computer. If the audio is stuttering, the processor on your computer may be working too hard, or your computer may not have enough RAM to run programs. Apart from testing the processor and RAM, the auditory test can also test the performance of your drive. Changing the PIO (Programmed Input/Output) mode to DMA will speed up the drive, and sometimes improve audio playback.
Step 5. Check your newly installed hardware
Most operating systems, especially Windows, can have problems with their drivers. Bad drivers or incompatible with certain applications can damage the stability of the computer. Check Device Manager on your computer by clicking Control Panel > System > Hardware and selecting Device Manager. Device Manager can be used to set hardware options.
Step 6. Check the software you just installed
Certain software may not be able to run on the computer due to limited system resources. If your computer becomes unstable after running a certain program, it is generally the cause of the computer's instability. If the computer has not been running steadily since starting, check the programs that were loaded when the computer started.
Step 7. Check CPU and RAM consumption
Slow computer performance may be caused by a lack of system resources. Certain programs may use too much CPU and RAM resources. Right-click the taskbar on your computer, then click Task Manager, and open the Processes tab. The "CPU" column indicates the percentage of CPU a process is using, while the Memory Usage column indicates the amount of memory used.
Step 8. Listen to your computer
If you hear a strange sound on your drive, shut down the computer and take it to a professional for a diagnosis. Unusual fan noise can also indicate that the computer is running above its capabilities.
Step 9. Scan your computer with updated antivirus and antimalware, such as Norton Antivirus, Avast
and Spybot Search & Destroy. Sometimes, poor computer performance is caused by viruses and malware.
Step 10. If you are unable to troubleshoot the computer, start the computer in safe mode
On most computers, you can start safe mode by pressing F8 at the POST screen. If the computer problem persists even in safe mode, you may need to repair or reinstall the operating system.
