When addressing issues with a computer’s power supply, it’s crucial to begin with the fundamental steps. First, ensure that the power cable is securely connected to both the power supply unit and the wall outlet. If the computer still doesn’t power on, try using a different power cable or outlet to rule out external issues. Next, check the PSU’s switch and make sure it’s turned on. If the problem persists, inspect the internal connections, ensuring that all cables are properly seated and that there are no visible signs of damage or wear. Additionally, testing the PSU with a power supply tester can help determine if the unit is functioning correctly. If the PSU is faulty, replacing it with a new one is often the best solution.
