Troubleshoot A Dead Computer PC No Power - Easily Fix A Dead PC

To troubleshoot a dead computer pc with no power, you must first start to check the electrical components coming into the PC like the main power plug and AC power cord. You should also check the front power button. If not fixed, then check the power supply unit (SMPS). In this tutorial I show you how to do all of that from basic to medium troubleshooting.

In this video tutorial I will show you the diagnostics tests to do when a computer won’t turn on.

You should follow a logical troubleshooting eliminating process. It starts with verifying the wall socket plug is working correctly. Next, check the power cord coming from the wall socket into the power supply. You can do this by either using a multi-meter such as the following:

Mastech Ac/Dc Auto/Manual Range Digital Multimeter, Ms8268, Green, Black &17.90

Alternatively you can plug the power cord into another device to test.

For this video the last test is the power supply. This can be tested in two ways. Firstly grab a different known working power supply and install into the desktop and test for operation.

If you cannot find a different PSU, then disconnect the 20+4 pin and the 4 cpu pins from the motherboard as well as any other power cables. Use athin metal wire such as a paper clip and bend into a U shape.

With the power supply switched off and unplugged, insert one end of the pin metal into a green slot and the other end into any black slot. Do not touch the pin further, plug in the power cord into the PSU and turn the switch on, if the fan spins then the power supply is working.

Please note at this stage that this test will only confirm power coming into the PSU and not correct voltage; i.e the PSU may still be damaged and not properly power the desktop.
