Advice 1: How to find a burned CPU or not

A blown element in a computer is always an unpleasant event. Typically, repair of such equipment difficult, and replacement expensive. But before you buy new hardware, you need to know what exactly burned out. Processor of computer doesn't burn as often, but it should start with him.
How to find a burned CPU or not
Instruction
1
Turn on the computer. Listen to the signals that are coming out of the speaker BIOS. In the instructions for alerts, BIOS will determine the cause of the fault. This will help to narrow your search. The fact that a blown CPU rarely issued by the BIOS, so if you do not find the signals, the suspicion of the processor increases. Sometimes it happens that when the computer is turned on, all coolers work, but the screen does not turn on. Do not rush to sin on the video card, if it is faulty BIOS you will understand their signals.
2
Disassemble the system unit. Will remove the CPU. Then, remove the radiator or remove it with special latches. If the CPU is blown, you will feel the characteristic smell. But, in practice it may not be. Also, inspect the space around the socket. It can be blackened, which indicates burnout. Try changing the thermal paste. Remember that it is impossible to cover the details of the thick layer paste. It needs to be thin and uniform. Then assemble the CPU and turn on the computer. If the screen is not lit, then the probability of burning out the CPU is pretty high.
3
Check the hardware on another computer. After making the first two steps, check the CPU on another computer. This is the surest way to determine the condition of your core. But it is also the most dangerous. There is a possibility of burning your motherboard of another computer. So please be careful. Do not use the computer for a long time, if convinced of the faults of the processor. As soon as you set your processor in another computer, don't forget to apply the thermal grease and radiator. Then turn on the computer. If the monitor screen lit up, all systems are functioning normally, then your CPU is OK. Otherwise you will have to replace it.
Note
When the Central processor was the first to break the gigahertz barrier that they had to have large heat sinks and powerful fans that can cope with the heat radiated by chips. Some products, such as the Intel Pentium 3 was off when overheated and Athlon 1200 could physically burn out if to take off his cooler.
Useful advice
Because no CPU is beeping it will not work (not to be confused with "siren" when the Board howls even without a CPU is already implemented funktsionalom of the chipset (South bridge). In General, in your case, you can check out - put of the processor to another (healthy) fee. "Simple" methods of diagnostics fee-naplata not by definition.

Advice 2 : How do you know that burned motherboard

Any computer equipment can break. Fortunately, in case of breakage of any component of the PC do not need to buy a new computer. Enough to figure out what has failed, and replace this equipment. Usually if a component fails, it can be determined according to several criteria. The hardest to determine if it will burn the motherboard, then the computer may not start. If the PC does not start all the time or is rebooted, you first need to check the motherboard.
How do you know that burned motherboard
You will need
  • Computer, motherboard, screwdriver
Instruction
1
If the computer does not start, the first thing you need to eliminate the possibility of breakage of other components. This will help to determine the serviceability of the motherboard.
2
You start the computer. First, it works to load. But as soon as it comes to operating system starts, the screen goes black and then nothing happens. So, out of order hard drive or video card. With the motherboard then all is fine.
3
Open the cover of the system unit. Pull out the motherboard, all memory modules. Turn on the computer. To hear the squeak of the speaker. If no, there's no sound and the motherboard does not react to the lack of memory modules, so it is out of order.
4
Pay attention to the capacitors on the motherboard. If they are slightly swollen, then, the Board is really burned. Bloating of capacitors can be caused by unstable operation of the power supply of the computer. The failure of the capacitors does not mean that the motherboard needs to be changed. To replace the capacitors can be at home, if you have experience soldering, or in the service center.
5
On some models of motherboards in case of failure of CPU when the computer is turned on can occur warning Install correct central core. Turn on the computer, if the system starts to boot and appears in the window this inscription, then, the motherboard is not burned, but broken CPU. In this case you need to replace the processor.
6
One of the surest ways to test the motherboard is. Unplug from the motherboard to the memory modules, graphics card, hard disk and all other devices. Leave only the CPU. Turn on the computer. If after it starts you hear the bell, so motherboard is OK. In this case, it broke one of the disconnected devices.

Advice 3 : How to determine fault in the motherboard

Almost every problem in the computer may be caused by a failure of its motherboard. But you have to understand, the reason may be in the wrong the work of other units and devices. How to distinguish one from the other, will be discussed below. But please remember – to make the connection or disconnection of devices inside the computer only when the power is off.
How to determine fault in the motherboard
Instruction
1
If any malfunction turn off the computer, remove the lid to see its contents. Visually inspect the motherboard. Verify the absence of gross mechanical damage. Check for swollen capacitors, charred parts. With a magnifying glass inspect for scratches and gouges on her tracks.
2
Your further actions depend on external signs of malfunction:- when you turn on the computer does not submit signs of life, go on to step 3;
- if you turn the computer on the fans run, LEDs lit on the motherboard, but the monitor stays dark and the PC speaker makes no noise, proceed to step 5;
- if the system speaker emits one short beep, then most likely the motherboard is OK, and the reason is the video card or the monitor;
- if you turn the computer normally boots, but then becomes unstable, i.e. sometimes spontaneously freeze or restart – go to step 9.
3
Eliminate the fault in the power supply, for example, replacing it with a known good.
4
Pull back and reinsert the cable connection between the power supply and the motherboard. Turn on the computer. Maybe it will work, and the reason was a bad contact in these connectors.
5
From slots unplug all devices except video card. To distinguish between a video card is easy – the cable from it goes to the monitor. Disconnect from the motherboard and power supply, hard drives, CD and DVD drives, drives, floppy drives. Disconnect all external devices except monitor and keyboard.
6
Turn on the computer. If the monitor displays an image, go to step 7, otherwise – to the point 8.
7
Turn off the computer. Connect the hard drive. Turn on the computer. If the monitor is dark again, the device is faulty and requires replacement or repair. Replace it with a serviceable. Complete this item for all previously disabled devices. It may happen that after the return of all devices in place the computer will function normally. This means that the reason was a bad contact of one device.
8
If after removing all the devices except the video card, the monitor remains dark, check the CPU, memory, and video card. You can check them out, setting into a working motherboard. Risky to do the check Vice versa, i.e. to insert into your suspicious motherboard serviceable device, this may bring them down.
9
Also, instability can be caused by overheating of the elements of the motherboard or power supply. Check that all fans are spinning normally, and the cooling radiators in the process, do not heat up much. For this you can turn off the computer and just touch them with your finger. They can be warm, but no more.
Note
Remember that many devices are afraid of static electricity. Therefore, it is desirable to work, not wearing electrified synthetic clothing, and before work is to play safe by touching a water pipe to remove any electrostatic charge.
Useful advice
You can turn on the computer with the cover removed, not forgetting about the General safety rules.

Advice 4 : How to determine the processor or not

There are dozens of types of different breakdowns of the computer, which he was not able to boot. If an error occurs, hardware BIOS emits a subtle sound signal with pauses. You need to count the number of long and short signals and to decrypt the message.

You will need
  • computer;
  • - the Internet.
Instruction
1
Matching the audio code and decoding of error available online, for example, on the page http://www.umopit.ru/CompLab/BIOSbeeps.htm. Identify the BIOS manufacturer of your motherboard. This information can be found in the documents for the motherboard. From the manufacturer depends on the decoding of the digital signals of the computer.
2
For AMI BIOS: CPU is faulty, if the system unit emits 5 short beeps. 7 short signals indicate an error virtual mode of the processor. Listen carefully to fully understand the problem on your computer.
3
For AST BIOS: an error occurred when checking the registers of the CPU, if the speaker has published 1 short beep. This indicates processor failure. In this case you need to contact specialized centers support how to fix a processor or reveal any problems almost impossible. You can simply kill all the "hardware" of the computer's own actions.
4
For Award BIOS: if the computer begins a high-pitched squeak during operation, the processor overheated and the computer need to shut down immediately. Alternating low-frequency and high-frequency signals after pressing the power button of the computer talking about the processor failure or overheating.
5
If your system unit does not produce any beeps, just try to replace the CPU or put your CPU in another motherboard. Make sure first that your processor can be installed in a different motherboard: the Socket type is the same, and the motherboard supports this processor. In extreme cases, you will have to buy a new processor for my computer or repair the old one.

Advice 5 : How to determine a burned CPU

Even in the most modern computer system can get literally any item. The reasons may be different: a power surge, defective manufacture, etc. Some items are repairable, some are not. It is important to determine what kind of item out of order and in a timely manner to replace it to complete the work on the computer.
How to determine a burned CPU
Instruction
1
Start your personal computer. In the event of a malfunction of the speaker BIOS will emit certain signals. This is the first sign. View the user manual for alerts BIOS. With its help, you will be able to determine what is the fault. It is possible that it burned the CPU, though, as a rule, such a fault is very rarely issued such alerts. If you turn on the computer, all coolers work, and the monitor is somehow not included, do not rush to identify the weak link in your graphics card. If it fails, the BIOS will let you know.
2
Disconnect power from your personal computer. Disassemble the system unit. To do this, remove the mounting screws on the side panel and slide it toward the rear side of the system unit. Remove the screws securing the cooler to the radiator. Then remove the radiator.
3
To do this, open a special latch. That's all you need in order to make sure that broken processor. Once you remove the radiator, in that case, if the CPU really burned, you will feel a characteristic smell which is difficult to confuse with any other.
4
Also inspect the surface of the motherboard around the socket. It may be blackened. Try to put on CPU thermal paste. Apply a thin neat layer. Then assemble the system unit and try again to start the computer. If the monitor still does not glow, then the probability that the processor is burned, is very high.
5
Connect your CPU to another computer. But remember, if your CPU is indeed faulty, there is a risk of burning your motherboard. To avoid this, don't keep the computer on for a long time. Before you start the other computer with your processorom, do not forget to put it on the radiator, a thin layer of thermal paste.
6
Then start the computer. If the monitor lights up, it means all systems are functioning normally and your CPU is OK. If not, then the processor has failed and you will have to replace it.
