How To Repair Your Computer That Turns Off After A Few Seconds

Did you encountered problem like this?

This problem is likely to occur in desktop computers but not in laptops. This trouble is not usual to manifest in laptops. As, I have said this problem is unusual in laptops but possible will occur. So, today we will focus on desktop computers.

If you encountered this problem in the future you will know how to fix it. So, I will start with on how to identify this problem.


If you already encountered this kind of computer trouble you will know what I am talking about.

When we start our computer, after few seconds computer turns off. In my experienced with this computer trouble 2-5 seconds computer turns off, then you have to turn it back on. And the same thing happens when powering it on, computer turns off.


 * What will be the possible part/s affected when this trouble happens? *

a. Power Supply
b. CPU Fan
c. Motherboard
d. Operating System

All these parts are suspect when this problem happens. So, which part usually failing?

If you are not familiar with these parts. Please see pictures of these parts below.



Power Supply





CPU fan






Motherboard














Operating System - I think everyone knows what is an operating system. But if ever you don't know what is an operating system, example of this is Windows 98, Me, 2000, XP, 7, 8, 10, Linux & Unix. These are only few operating system that are common and well known. 


Okay, Lets get back to the computer problem. If you have problem with operating system, the computer only restart but not turns off immediately.

If we have defective/damage motherboard, the system will also reboot or won't turn on.

For defective CPU fan, the system also turns off but not immediately.

The problem is in defective power supply. If the power supply has a problem with overheating or defective parts, it usually turns off immediately.


 * How to solve this problem? *

 Just replace the power supply, but be sure to double check if the power supply is the main problem or the motherboard. Because sometimes motherboard also become damaged if your power supply gets defective.

But in my experienced when system turns off immediately this problem always associated with defective power supply. Even if it is a newly assembled computer.

For laptops, you have to identify the problem or short in the power supply which cause the trouble. I cannot give you a specific part/s to pull out or to replace. It's up to you to discover what part/s to replace to solve this problem. I can only give you a tiny hint try to check if the power IC of you laptop is shorted.



Conclusion:

Problem on power supply sometimes comes with other part/s damage due to voltage or current spike. So, when troubleshooting a desktop computer you should always double check parts that somehow could be affected.

Most Common Problems on Automatic Voltage Regulator

Image
Hi there, today my post is about automatic voltage regulator. What goes into your mind when you hear the term automatic voltage regulator? Yes, its automatically regulate voltage, right? So how this automatic voltage regulator affects our computer? Actually this device does not affect computers directly. This device does not speed up our computer but it protects our computer parts from easily burned during voltage fluctuation. Also it provides step down power for devices from Japan or the US. If we live in Asia and plug this devices, this action could be a disaster to this devices. In Japan and US voltages are in 110volts to 120volts only while in Asia most devices runs in 220volts. So, this AVR is not only for voltage fluctuation but also as step down power. So, what are the most common problems of automatic voltage regulator? I have here the list of problems that we might encounter if we have a defective automatic voltage regulator. 1. Defective Plug Defective plu

Typical Computer Headset Wiring Diagram - Barkingmode.

Image
Hello guys, I have today a wiring diagram which I traced the wiring from a cheap headset. Drawn and transferred to a computer to create a .jpeg file. I also, color it so that it will be easier for everyone to analyse the connection. This will help us remember the connection easily if we break the wire unintentionally. Having a wiring diagram connection of plug and wiring will be easier for us. See the headset wiring diagram below. The speakers on the drawing is a symbol and not the real thing as a drawing. Volume and microphone is a real image as a drawing. Only the Left and Right speakers are the symbol on this wiring diagram. You can also identify the location of the left and right speakers in the speaker plug. The mic input in the plug also shows its pin configuration and wiring of the microphone. This will help us locate easily the pin of the speaker in the plug or the mic-in in the mic plug. Last modified: Aug. 31, 2019.
