You need to fix a PC power problem if the computer’s power supply stops working, either the computer will either not turn on or turn itself off at random times. Although your first instinct may be to transfer your PC to a technician, you can instead troubleshoot the power supply yourself at home. Your computer does not consume energy directly from a wall outlet but instead needs a power source to convert regular electricity into less electricity.
When the computer suddenly switches to Fritz for no apparent reason, checking the computer’s power supply first may save a lot of time to troubleshoot system errors. The faulty computer power supply is causing a lot of intermittent computer problems. This is why experienced computer technicians often first look at the PSU when diagnosing computer problems.
- The system failed during the boot process.
- The computer is not working at all
- Restart or auto shutdown when trying to use the device
- Cans and spinless hard drives
- High-temperature system due to heatsink and fan failure
- Errors system memory errors
- Screen BSOD

How to Fix a PC power problem
Here are some notable ways to fix your computer power when it’s malfunctioning.
Redundant power supplies
The weak or inadequate power supply can hinder your ideas of expanding the system. Some systems are built with toxic power supplies as if they anticipated a lot of system add-ons and expansion components. Most desktop or tower systems are built this way. However, some systems have insufficient energy supplies from the start, and they cannot serve the energy-thirsty options you might want to add enough.
The rated wattage can be very misleading at times. Not all the 300-watt supplies themselves are created. People familiar with advanced audio systems know that some watt is better than others. This applies to energy sources as well. In fact, cheap energy sources may release estimated energy, but what about noise and distortion? Some supplies are less than engineering to barely meet their specifications, while others may exceed their specifications significantly.
Many cheaper supplies provide noisy or unstable energy, which can cause many system problems. Another problem with poorly engineered power supplies is that they can work hot and force the system to do so as well. Repeated heating and cooling of the solid-state components ultimately causes the computer system to fail, and engineering principles dictate that the hotter computer temperature shortens its shelf life.
Many people recommend replacing the original supply in the system with a heavier model, which solves the problem. Since power supplies generally come in, finding a heavy-duty replacement for most systems is easy, as is the case with the installation process.
Some of the available alternative energy sources have cooling fans with a higher capacity than the original ones, which can greatly extend the system life and reduce overheating problems – especially for newer and hotter processors.
If system noise is a problem, models with special fans can operate more quietly than standard models. These power sources often use larger-diameter fans that spin more slowly, so they run more quietly but move the same amount of air as the smaller ones. PC Power and Cooling specializes in heavy and quiet supplies; Astec has many heavy models as well.
Ventilation in the system is also important. Ensure adequate airflow to cool the hottest elements in the system. Many processors today use passive heatsinks that require a continuous stream of air to cool the chip. If the processor heatsink has its own fan, this is not a major concern.
If you have free expansion slots, you must empty the panels in your system to allow air to flow between them. Place the hotter operating panels near the fan or ventilation holes in the system. Ensure that there is sufficient airflow around the hard drive, especially those that spin at high speed. Some HDDs can generate a lot of heat during operation. If the hard disks warm, you may lose data.
How to Fix a PC power problem
First, disconnect each power supply input port or output port connected to computer components.
- Open the power supply box, clean the interior of the power source and check if there are burning components, usually burning is an Elco component.
- If there is, check the components and replace them with new ones. If not, did the fuse’s inspection department check whether it is in good condition or not, by measuring it using an ohmmeter.
- Next, check the 2SC3039 power switch transistor (two pieces) that has the PWM power supply control function.
- Remove two transistors from the PCB to check its status. If still good, go to the diode bridge section.
- Check the status of each diode using a multimeter. The power supply is often damaged due to a leaking diode.
- Next, check the pulse generator transistors and capacitors as well as the resistor on one block of the pulse generator circuits. Ensure that all ingredients are still good and working well.
- Don’t forget to check each welding point for the components. Make sure there is no separate weld, keeping in mind that the temperature inside the power source is hot.
- If all components are inspected, and the condition is normal, the ICTL494 component may be damaged. To verify the IC494 IC component, a multi-device cannot be used.
- Therefore, you should try to replace the old TL494 IC components with a new one.
- Take the test again.
