My PC suddenly turns off

A computer suddenly turns off due to several reasons which may be a result of electrical short or a serious hardware concern. It is not easy to immediately detect the main cause of the problem, so it is important for you to perform logical troubleshooting procedures to spot the issue. Here are the most basic yet very helpful steps that you can follow:

1. Always make sure that the power supply voltage switch is set correctly. Depending on your country, the power supply’s input voltage has its proper setting. The wrong setting causes the computer to turn off on its own.

2. Take the time to check for electrical shorts inside your computer as it is most often the reason for a computer to shut down before completely turning on. It is very important to detect simple electrical short instead of replacing more costly hardware components later on.

3. Power supply testing is also very important since it is most likely causing problems than any other hardware in the computer.  When a computer turns on for a few moments doesn’t mean that the power supply is working properly. It is wise to consider trying other power supply units to isolate the issue.

4. Reseat everything inside your computer. Some connections inside the computer may need to be firmly secured in place which could possibly have come lost over time. Hardware components such as the RAM, video card, hard drive connections and power cables need to be tightly in place at all times.

5. Reseat the CPU only if you are absolutely certain that it might have come lost. This is unlikely to happen and requires more expert hands for installation.

6. Try to power on the PC with essential hardware alone. While maintaining the computer’s ability to power on, try to remove as much hardware as possible.

7. If step 5 has been performed, try to reinstall each piece of nonessential hardware one at a time. This will allow you to determine the one hardware that may have caused the problem. This is a tedious but very important step to solve the puzzle since one defective hardware can cause the whole computer system to shut down.

8. Test your PC by using a Power On Self Test card. If the PC continues to turn off with only essential PC hardware installed, a Post Card will help locate the problem hardware.

9. Replace each piece of essential hardware with a “known good” identical spare piece. Install one hardware at a time allowing you to figure out which one is defective.

10. If computer continues to turn off, professional help is recommended or contact your computer manufacturer’s technical support.
