Understanding CPU (Processor) Failure Symptoms
The Central Processing Unit (CPU), the brain of a computer, controls all the actions that take place inside your computer. Also known as a processor, the CPU has small transistors, and even a minor issue with any of the transistors can cause the main processor to fail. Bad capacitors, usage for an extended time, voltage issues all can cause CPU failure. The good news is that CPUs give you signs that trouble is coming. Diagnosing these signs and fixing the issue on time can enhance the processor’s life for long years. Let’s hear out our Perth IT helpdesk on what are the signs of CPU failure and how to decode them.
What are the Signs of CPU Failure
Consider taking immediate action whenever you come across these symptoms, or you can end up with a dead CPU. Some of the CPU failure symptoms you need to be aware of are –
One of the most common signs of CPU failure is the random freezing of your computer, usually after just logging into the operating system. The system won’t respond to any of your instructions. The mouse freezes on the screen and any attempt to use the keyboard will result in a series of short beeps. Restarting the system may not solve the issue. This may also indicate that the motherboards are in critical condition.
Normally you will hear a beep sound when your computer is powered on. However, in case of a CPU failure, there can be booting issues such as – blank screens, no beep after the boot and no response on pressing keyboard keys or clicking the mouse. If you are comfortable opening up the computer, check for the motherboard LEDs. If they are lighting up, but the system refuses to boot, then it’s a clear sign of processor failure.
Computer Automatically Turns Off
A Blue Screen with Error Code
Referred to as a Blue Screen of Death (BSoD), this can happen due to multiple factors, including RAM, motherboard and CPU failures. If your screen displays the error code 0x00000, then it is an indication of processor failure.
Each time the computer is booted, it checks whether all the components of the PC are functioning properly. This is called the POST test. If you hear irregular beep sounds, a failing CPU can be one of the reasons. A CPU issue will usually cause a series of 5-7 beeps. However, a trained technician will be able to help you better at decoding the beeps.
External Appearances of Damage
A computer can show signs of CPU damage even without booting it up. Overheating can cause damages that may be visible externally. Any burnt marks on and around the CPU socket indicates that the CPU has undergone extreme overheating. In such situations, a replacement may be the only option.
Motherboard – is a printed circuit board that connects all key components and allows communication between them for smooth system operation.
Error codes – are codes displayed on a blue screen during unsuccessful booting. Each error code signifies a particular problem.
POST test – Power On Self Test is a series of test run by a computer at the start of the booting process to check if all hardware is working properly.
