One common problem faced by owners of low-end computers is the sudden shutdown of the computer shortly after pressing the power button to turn it on. The cooling fan starts spinning, everything seems to be working, but then it shuts down before Windows can boot up. The screen remains black with no display. In an attempt to solve this issue and continue using your computer without problems, author Mahmoud Monir reviewed the reasons and solutions for the computer shutting down during startup. Today, based on this article, I will propose a solution that may help your computer work normally.
– It’s time to change the processor fan
The primary factor that can cause a computer to shut down shortly after being turned on is the processor overheating to the maximum extent once the computer is started. The high temperature does not allow the processor to perform the required tasks, as the fan may not provide sufficient ventilation or may be running slowly, ultimately leading to the disabling of the processor and all computer components. Therefore, check the fan’s operation during computer startup and ensure it is spinning rapidly to provide adequate cooling for the processor. If it is found to be operating inadequately, consider purchasing a new one. I recommend reading this article on how to choose the best CPU cooling fan suitable for your computer to select an authentic quality fan.
– Change the thermal paste
Even if the fan is working efficiently and providing proper ventilation for the processor, the problem may persist whenever you start the computer. In this case, the issue may lie with the thermal paste applied between the processor surface and the heatsink to distribute cooling evenly across all processor cores. This paste can deteriorate and dry out after extended computer use. Therefore, one solution to the problem of the computer shutting down shortly after startup is to replace this paste with a high-quality one to prevent temperature spikes. It is recommended to do this regularly to maintain the processor’s lifespan for years.
– Replace the power cable or power supply
The issue may be related to power, specifically the power supply. A problem with the power supply may prevent it from supplying the required power to all hardware components in the computer. If you are using a poor-quality or cheap power supply, then power could be the cause of this issue. Before buying a new power supply, try using a different power cable to ensure the problem is not with the cable, as it may have a fault that disrupts the electricity flow to the power supply.
