Troubleshooting a computer’s power supply is an important step when a computer will not turn on or randomly shuts down. One of the first things to check is the power cable and wall outlet. Sometimes the issue is as simple as a loose cable or bad outlet, so testing the outlet with another device can confirm if power is actually being delivered.
Another common technique is checking the power supply unit switch on the back of the computer. If it is turned off, the system will not receive power. It is also helpful to listen for signs like fans spinning or lights turning on when a power button is pressed.
You can also unplug unnecessary components such as extra hard drives or graphics cards to see if the system will power on with a smaller load. In some cases, using a PSU tester or swapping the power supply with a known working one can help confirm if the PSU is faulty.
Overall, careful inspection and simple tests can help identify power supply problems.
