How to prove that there is a problem with the CPU, is the CPU easy to break How to tell?

Generally speaking, CPUs are really not easy to break. Among the various parts of the computer, the CPU and the memory are the two most durable parts.

Method steps.

Under normal use, the life span can easily pass 10 years. You can take a look at the hardware on the market now, 10 years ago, dual-core Core, Athlon X2 processor, that is a lot of hair. There are also DDR and DDR2 memory.

In addition to the damage to the core and internal circuits of the CPU, there are some external faults that can still be repaired. For example, the pins are crooked, the capacitors are off, and the ...... is soldered againThe pins are easy to say, and the capacitance that is soldered back by professionals may also lead to the phenomenon of instability on the machine......

The processor is one of the most important accessories in a PC, and all kinds of data operations and processing processes are completed by the CPU processor.

If a computer is compared to a human body, then the CPU processor can be regarded as the human brain, which controls the coordinated operation of various parts of the overall machine. Due to the high degree of integration of the CPU processor, its reliability is very strong, and the probability of CPU processor damage and burn is not very high in the case of correct use of the computer, but it cannot be ruled out that the CPU processor is damaged and burned due to human reasons. Especially in the case of installation process and overclocking use, it is very easy to cause CPU damage and burning.

Especially in the case of installation process and overclocking use, it is very easy to cause CPU damage and burning.

First: Check the main frequency, which is the clock frequency of the CPU, which is simply the working frequency of the CPU during operation. The higher the frequency, the more instructions can be completed in a clock cycle, and of course, the faster the CPU.

Second: check the memory bus speed, the data we put on the external memory must pass through the memory, and then enter the CPU for processing. Memory bus speed refers to the speed at which the CPU communicates with L2 cache and memory.

Third: check the speed of the expansion bus, the expansion bus refers to the local bus installed on the microcomputer system such as VESA or PCI bus, and the expansion slot in the computer is the bridge between the CPU and these external devices.

Introducing: CPU

CPU is the first processor, which is one of the main equipment of electronic computers and the core accessories in computers. Its function is mainly to interpret computer instructions and process data in computer software. The CPU is responsible for reading the instructions, decoding the instructions, and executing the core components of the instructions.

Control Unit: The control component is mainly responsible for decoding instructions and sending control signals for each operation to be performed to complete each instruction. There are two types of structures:

One is the microprogram control mode with micromemory as the core; One is the control mode based on the logical hard wiring structure. Microcode is maintained in micromemory, and each microcode corresponds to one of the most basic microoperations, also known as microinstructions; Each instruction is composed of different sequences of microcode, and this sequence of microcodes constitutes a microprogram.

Expand; The external frequency is the base frequency of the CPU, and the unit of the external frequency determines the running speed of the entire motherboard. In layman's terms, in desktops, the overclocking is the external frequency of the super CPU, and I believe this is well understood. But for server CPUs, overclocking is absolutely not allowed.

As mentioned earlier, the CPU determines the running speed of the motherboard, and the two run synchronously, if the server CPU is overclocked and the external frequency is changed, asynchronous operation will occur, which will cause the instability of the entire server system.

There are ways to determine whether the CPU is faulty: the computer will not turn on, frequent blue screens or freezes, running slowly, overheating problems, CPU failure warnings, checking CPU hardware, etc.

1. The computer cannot be turned on

If your computer won't turn on at all, or if nothing happens after turning it on, it could be one of the signs that something is wrong with your CPU. You can make sure that your computer's power supply is working properly, or try testing it with a different power supply that you can rely on.

2. Frequent blue screens or freezes

If your computer is experiencing frequent blue screens or freezes, it could be one of the signs of a faulty CPU. You can look at the blue screen error** or the logged error message to determine if it's CPU-related.

3. The running speed slows down

If your computer is significantly slower and your applications are unresponsive, it could be due to a decrease in CPU performance or a glitch. CPU usage and frequency can be observed through Task Manager or other system performance monitoring tools, and under normal usage, CPU usage and frequency should be kept within a reasonable range.

4. Overheating problem

If the CPU overheats, it can cause the computer to crash or restart frequently. You can use temperature monitoring software to check the temperature of the CPU, if the temperature is persistently too high, you may need to clean the heatsink or replace the heatsink, if it is still overheating, it may be that the CPU is malfunctioning.

5. CPU failure warning

Some motherboards will provide a CPU failure warning function, and when there is a problem with the CPU, the motherboard will sound an alarm or display a fault light. If you encounter such warnings, you should immediately check your CPU for failures.

6. Check the CPU hardware

Most of AMD's CPUs are pin-type, and after getting the CPU, you should check whether the pins are skewed or broken, and whether the PCB is deformed; Most of Intel's CPUs are contact type, and more need to check whether the contact pins on the motherboard are deformed or broken, because the pins on the CPU are not very important, some may not have any impact, and some may affect some functions and memory support of the CPU.

As the core equipment of the computer, the CPU is responsible for processing all the internal data of the computing computer, and once the failure will paralyze the entire computer, how to detect whether the CPU is damaged? Here's what I've put together for you, I hope you find it helpful.

1.If the computer does not turn on, open the main case of the computer to check whether the CPU is plugged in, and if not, you can reinsert the CPU.

2.Check the power supply system to see if the power supply is normal, whether the voltage setting is correct, and whether there is a short circuit or open circuit.

3.Check the fan, open the computer case, check whether the CPU fan is installed correctly, and reinstall it if it is incorrect. If the installation is correct, check whether the CPU fan is running normally, and replace it if it is not.

4.Check the heat sink, check whether the CPU heat sink is installed firmly, whether the heat sink is in good contact with the CPU, and reinstall it if it is not firm, and coat the heat sink with silicone.

5.Remove the CPU fan to see if the CPU is burned or crushed, and you can test whether the original CPU is normal on another computer.

6.If all of the above checks are normal, turn up the CPU working voltage through the BIOS settings or motherboard jumper to see if the fault disappears, and restore the CPU frequency if it still exists.

7.This completes the detection of the CPU.

1. It can't be turned on, that is to say, even the power can't be started, and the computer doesn't have any response;

2. The power is turned on, the CPU fan is also turned, but the monitor screen is black;

3. The computer can boot, but there is an error when running some programs, or the system is out of order.

1. In the case of broken pins, you can repair the pins.

2. If the internal control circuit of the CPU is damaged, the damaged electronic components can be replaced after the top cover is opened.

3. The CPU burns out at high temperature, and this cannot be repaired.

As an ordinary user, the easiest way to repair a CPU is to re-straighten the CPU pins after being accidentally bent.

If you suspect a CPU problem, you can follow the following steps to troubleshoot it:

1.It is possible that the CPU is not powered: You can use a multimeter to test the three (or one) field tubes and three (or one) rectifier diodes around the CPU to check whether the CPU is damaged.

Socket missing or loose: This type of fault is manifested as a failure to light up or irregular crashes. You need to open the upper cover on the surface of the CPU socket and carefully observe with your eyes if there are any deformed pins.

The fan fixing clip of the socket is broken: consider using other fixing methods, and generally do not replace the CPU socket, because manual soldering is easy to leave hidden faults. Socket370 CPU, its heat sink is fixed through the CPU socket, if the fixing spring is too tight, you must be careful when disassembling it, otherwise it will cause the plastic clip to break, there is no way to fix the CPU fan.

4,.The CPU frequency set in CMOS is incorrect: just clear the CMOS to solve the problem.

Clear the CMOS jumper is generally near the lithium battery of the motherboard, its default position is generally short circuit, as long as it is changed to short circuit for a few seconds to solve the problem, for the old motherboard, if you can't find the jumper, just remove the battery, and then shut down after the boot display enters the CMOS setting, and the battery can also be installed to let the CMOS discharge.

CPU rarely goes wrong (normal use).Only the motherboard does not fully support the CPU, you can see when you boot the CPU information is consistent with the installed U, you can also use CPU-Z, if it is inconsistent, you are either deceived by JS, or the motherboard does not support the CPU perfectly (generally you can use the same flashing BIOS to implement perfect support).

The CPU will not have a problem, as long as the CPU is turned on and the display screen is no problem.

Use the CPU-Z software to see if it matches the logo on your CPU. Then test the speed of the CPU with Super- software.

There are two major brands in the world of CPU: AMD and Intel.

AMD's CPU** is generally about 30 to 100 yuan cheaper than Intel's CPU with the same performance, and many DIYERS prefer AMD because they can buy the same performance for less money; In addition, in order to compete with Intel, AMD's CPUs are designed to be easy to overclock, that is, by adjusting the supply voltage and system parameters, AMD can run at a speed higher than the design frequency to obtain higher performance.

However, Intel's CPU is more stable, easy to debug, and with the same performance, although it is more expensive than AMD, it is more worry-free.

Therefore, identifying the quality of the CPU is mainly determined by your hobbies and uses. If it's just mainstream playing ordinary web and online games, Intel is enough. But if you're looking for hands-on fun, AMD can help you learn more.

For the same brand of CPU, the decisive factor for identifying good and bad is first of all, new products. No matter how strong the second-hand goods or the Mengren labor package goods are, they are basically synonymous with inferior quality, and there is no way to complain.

Secondly, it is the process process, the CPU of the new generation process, even if it does not have more frequency and core than the old process, but the performance is often better and the power consumption is lower;

Third, the same brand, under the premise of the same process, is more powerful than the core;

Fourth, for the same brand, if the process is the same and the number of cores is the same, it is the frequency; The higher the frequency is better;

Finally, if the brand, process, core, and frequency are the same, the last thing is to look at the cache, and the cache is larger.
