How to Troubleshooting a Dead Computer Without Warning

Computers die broken aliases can arise in two ways and if the computer is off and no warning beforehand, it means that you can still find out about what the source of the problem.

But if it is being used and suddenly the computer turns itself off without any warning? What are the causes and the solutions? This is the solution:

The cause and the solution can be one of the below possibilities.

1. Computers are too hot or overheated 
2. Problem error / hardware malfunction. 
3. The virus computer. 
4. Problems with the operating system for example Windows . 
5. Another failure of hardware

Computer too hot or overheated.
A computer can turn itself off without warning if it has exceeded the maximum heat required (especially Processor). Many computers today are designed to shut down or reboot automatically if the computer, processor, or other devices on your computer to overheat. If you've heard the voices that are not normal from your computer like a buzzing high, this could indicate a failure in your computer.

You can start by checking out the fan in the power supply to check the back of the computer is off and see if the fan moves smoothly. You can also open up the computer and make sure the fan works (processor fan and the fan casing) and / or if the VGA using a fan, then please go into the BIOS and make sure the BIOS does not report any errors. Note also the location of the aluminum cooler because if the position is not right, then even if there is a fan, the cooling process will remain masalah.Pengguna may also be able to determine how hot the computer with onboard thermal sensor. If your computer is equipped with a sensor, make sure you are not active CPU overheat

Problem error / hardware malfunction
Any failure of your computer hardware components can cause your computer to unexpectedly die without warning. If you recently added new hardware, make sure it does not cause problems for your computer. Before attempting to open the hardware, make sure you do not run into problems due to a hardware conflict by looking at the Device Manager to check for errors.
If problems arise when you just installed new hardware into the computer, then certainly the cause of this new device. Start the computer after opening the earlier device and observe if the problem is completed or not.

Virus Computer
Maybe your computer is infected with a virus that is designed to turn off your computer. If the computer Matia itself when running a specific program at a specific time, such as a computer directly only die if you run the program Word then that's a sign that the program is infected or infected with a virus. If you believe your computer may be infected with a virus or are not sure whether your computer is infected with a virus, make sure you do scan whit latest anti-virus.

The problem with the operating system.
If after following all the above recommendations your computer still continue to die alone, chances are you have problems operating system of Microsoft Windows that is difficult to explain. To help ensure that this happens, please try the steps below.

Reboot the computer and enter CMOS setup as the computer is booting. If you are not familiar with how to enter CMOS, please download the Guide to Become a Computer Technician I prepared on the side. Once you have opened the computer in the CMOS setup, leave the computer for a while. If the computer does not die in some time meant he was able to survive the road in the BIOS then the probable cause is a Microsoft Windows. If this happens the solution is in the book Guide to Become a Computer Technician Another failure of hardware

If after reinstalling your operating system, or during the installation of your operating system, the same case is still going on, it is possible that there are other hardware failures in the computer. Often occurs for example RAM, CPU, motherboard, and / or Power Supply. If you have an extra supply of these parts or have a friend or co-worker with the same configuration, try swapping these parts to determine the problem you.If not, you need a more senior technician services, please read Theoretical computer science.

Damage Hardware Laptops The Most Common And Solutions

There are so much damage to the laptop , especially the problem of laptop hardware damage . Pretty much difference with the PC that looks much more friendly . In this post I will summarize the problems of the most common laptop hardware and solutions respectively . That means that this article is not final and will end when all these issues been discussed.

Problem # 1. Total dead laptop.
Description of the problem: When you plug the AC adapter into the laptop, no lights turn on at all. When you press the power button, no reaction occurs. Laptop seems completely dead, no sound, no indication of life.

Possible problems: AC adapter fails and the battery is fully discharged. First, test the AC adapter. If it dies, replace the adapter.

Description of the problem: the laptop is on, the LED lights on the laptop is on, the cooling fan is working but nothing appears on the screen. The screen is completely black and empty. No images on the screen at all, even very dim picture also does not exist.

Possible problems: This problem can be attributed to a failure of memory. Probably from the memory module failed and the laptop does not turn on because of it. In this case you can try reseating the memory module to ensure proper contact with the slot. You can try removing memory modules one by one and test the laptop with just one memory module installed. You can try replacing the memory module with the new module. If reseating / replacing a memory module does not help, try to remove the hard drives, DVD drives, modems, wireless card, keyboard, etc ... In other words, disassemble the laptop and installed only minimal equipment and test again. If the laptop still does not turn on, most likely failure motherboard or processor.

Problem # 3. Laptop turns on and then die again.
Description of the problem: Laptops turn on without showing any image on the screen. After a few seconds the laptop will shut itself down. Then turns on and off again. It keeps going until we turn off the laptop completely.

Possible problems: Most likely it happened because of some kind of motherboard failure. You can try reseating / replace memory as I described in problem 2. If it does not help, mean  damage the motherboard. In most cases, it is very difficult to replace the motherboard, it's better to buy a new laptop.

Problem # 4. Laptops are very noisy.
Description of the problem: Laptop turns on and everything is working well, he made a few oddities that noise and crackling. Some laptops make noise all the time, other laptops only intermittently.

Possible problems: In most cases this noise coming from the cooling fan or laptop hard drive. You can turn on the laptop, wait until the voice came again, and then listen carefully to the bottom of the laptop. If the laptop is making noise when the cooling fan starts running, most likely damaged. Replace the cooling fan. If the laptop is making noise even when the fan is not spinning, maybe it comes from the hard drive. Back up all personal data from your hard drive as soon as possible, the total damage may occur at any time. Replace the hard drive.

Here is another technique to find out whether the noise coming from the fan or hard drive. Remove the hard drive from the laptop and start the laptop. Wait until warm and the fan starts spinning. If the laptop is still making the same sound even when the hard drive is removed, most likely a faulty fan.

Problem 5. Laptop die or crash when being used.
Problem description: Laptop up and running properly, but after a while directly hangs or die without any warning. When that happens, the laptop feels hot on the bottom. Also, the cooling fan to work harder than usual.

Possible problems:
Most likely this is a hot issue processor. This happens because the cooling module clogged with dust and the laptop can not "breathe" properly. The laptop is turned off or j
ammed because the processor (CPU) is too hot. Clean the cooling fan and heatsink to fix the problem.
