How to Fix a Fried Computer

Updated: Aug 7, 2022

The simplest way to fix a fried computer is to replace the damaged parts and components. Before doing so, be sure to have a replacement ready in order to avoid buying unnecessary parts.

How to Fix a Computer

Your computer can get fried due to one or more of several reasons. Commonly, an electrical surge will ruin your computer's hardware and excessive heat might damage the hardware components as well. Electrical surges can happen because of the power grid and electrical storms while damage can occur because of overheating. Whenever this happens, you can attempt to fix your fried computer before paying a professional to fix it.

Step 1

The cable removal step is the most important one. You are disconnecting the fried computer from all of its power sources, which will eliminate any current flow. Make certain that all of your cables are disconnected and then press the power button to insure that there is no charge. Remember, if there is a charge present it can damage you too. Next, place your fried computer on its side on a flat and clean work surface.

Step 2

Remove the side panel of the computer so that you can see all of the computer's internal components.

Step 3

Look for telltale signs of a damaged component, such as black scorch marks or swollen capacitors.

Step 4

Remove any obviously damaged parts.

Step 5

To troubleshoot a computer, remove each individual component one at a time. Place a new or working component in its place. Plug the computer's power cable into its power supply and an available power socket. Attempt to turn the computer on after inserting a new or working component into an old component's place. Replace each new component with the old component after each test to keep the parameters of the test the same for each component. This is a process of elimination and can help you isolate which components are causing your problems.

Step 6

When troubleshooting a computer that doesn't turn on, replace all of the old components with new or working ones. Turn it on. If the computer still doesn't turn on, it is possible that the motherboard is at fault. Test it with a different power supply at this point as well, because if the power supply is fried then no power will reach the other components. If you discover that the power supply is also burned out, after replacing it with a new one reinsert your old components and turn the computer on after each component to determine if any of those are also burned out.
