If your computer malfunctions frequently, it could either be a software issue or a hardware problem. Common symptoms of a malfunctioning computer include frequent crashing of running programs, freezing and slow speeds. However, diagnosing a computer to establish whether the problem lies in the software or hardware is no walk in the park. Here are some tips to help beginners diagnose common hardware problems.
Power Supply Unit Issues
As the name suggests, a computer power supply unit relays power to essential peripherals of the device. Therefore, the failure of a power supply unit can be catastrophic to the entire computer system. A power supply unit malfunction is often caused by a power surge, which damages useful electrical components. One common sign of a faulty power supply unit is the failure of cooling fans. A technician uses special tools to test the functionality of connectors in a power supply unit. Also, they use an electronic meter to test the voltage output of different connectors. In most cases, a damaged unit needs to be swapped for a new one. Note that motherboard components should be measured to ensure that a power supply unit failure did not affect the parts.
The central processing unit (CPU) is the heart of a computer system. For instance, the CPU enables a computer to load an operating system and run various peripheral devices. Symptoms of a bad CPU include overheating and crushing. Therefore, during routine computer maintenance, ensure that all computer fans, including the CPU fan, are devoid of dirt and dust to avoid overheating. A self-check system integrated into an operating system helps show if a CPU is malfunctioning. Repairing a CPU as a DIY project is not recommended if you are not an expert. You should take the device to a technician for diagnosis and subsequent repair.
One common sign of a troublesome CPU is a beeping sound from the motherboard, which could mean many things depending on the number and pattern of beeps. However, a technician can decode the sound using the make and model of a computer to establish whether a CPU is faulty. Deep cleaning a CPU can help address overheating. A faulty CPU can be replaced with a new one bearing the same specifications, such as processing power, storage space and memory. Alternatively, you can upgrade a CPU for enhanced performance, but it costs money depending on the features you want.
