Help determine if the CPU is bad or the motherboard is bad?

Don't easily determine that it's broken, it may also be a bad contact, memory and motherboard, CPU and motherboard, graphics card and motherboard are not in good contact with the motherboard, sometimes the problem is not necessarily called, I'm talking about the motherboard, you take off the motherboard BIOS battery, discharge and then install it, you try more of the above situations, it is recommended to use the hardware detection card to look down, you can know the reason for the above place, the computer's tweeting is often inaccurate, especially the memory, the contact is not good, some are called, some are not called,

There are two on the motherboard.

Memory sticks. socket, when one of them is plugged in, the boot will have a continuous alarm sound:

This phenomenon is that your memory module and slot are not compatible.

If it can't be turned on directly, and there is no sound, it should be that the CPU is broken.

You've been deceived, and you don't want to talk about anything else. The advice I give you is: you don't know how to do it, you believe what others say, people say that the motherboard is broken, you pay to repair it; People say that the CPU is broken, and you pay to fix it; So why don't you get the bad hardware back that you replaced?

Are you sure you changed the motherboard?? (The general workshop-style maintenance point is not professional at all, and it is not as good as DIYER).

If you put your CPU on another normal computer and it can be turned on, the CPU will not be broken.

Put another good CPU on your own motherboard to turn on, and the motherboard will not be broken.

You can see why I have at least 3 computers.

Symptoms of a broken motherboard:The boot fan turns but the monitor does not display, pressing the power button cannot turn on or does not respond at all, the motherboard power pin shorts also does not have any response, and the BIOS display has garbled characters after powering on.

Symptoms of a broken CPU:Black screen, no alarm sound when booted, the calculation data will be very slow, and in serious cases, you can't even turn on the computer.

CPU considerations.

There is a certain relationship between the main frequency and the actual computing speed, but it is not completely decisive, because the computing speed of the CPU is also related to the performance indicators of all aspects of the CPU pipeline, such as cache, instruction set, architecture, process, etc.

The performance of the CPU cannot be determined solely by the number of cores, but also by the strength or weakness of the brand. In general, Intel single-core is equivalent to AMD dual-core.

How to check whether the processor is damaged or the motherboard is broken, generally speaking, to check whether the motherboard of your computer is broken or the CPU is broken, in fact, in most cases, the motherboard is damaged, because the processor is the longest life and the least easy to damage in the computer hardware, unless it is some man-made damage that may cause the processor to break, according to normal use, more than 99% of the motherboard is broken suddenly, The best way to check is to take out the processor and put it on a different motherboard to test it, which can light up to prove that the CPU can't be lit up, and the CPU is damaged

If you want to check whether the CPU is broken or the motherboard is broken, then it is very simple, the main thing is to use the replacement car to replace the car for inspection, for example, you can change a CPU of the same specification, if the computer is normal, then it proves that the CPU is broken, otherwise it should be the motherboard is broken.

The easiest way is to borrow a set of CPU motherboards with compatible interfaces to replace the test.

Of course, there may also be failures caused by incorrect driver version selection, so it is better to troubleshoot software problems first.

1. Symptoms of a broken motherboard:

1. The boot fan turns but the monitor does not display, and pressing the power button cannot turn on at all or there is no response.

2. There is no response to the short circuit of the power pin of the motherboard, and the BIOS display has garbled characters after booting.

Solution: If the motherboard is broken, because the motherboard is very precise, the technical requirements for repair are very high, so there are very few shops to repair the motherboard, and they all take the method of directly replacing the motherboard.

2. Symptoms of a broken CPU: The CPU is not easy to break, unless the power supply is insufficient or burned.

1. Black screen. There is no alarm sound when the machine is turned on.

2. The calculation data will be very slow, and it is even impossible to turn on the computer.

Solution: The CPU is broken, as an ordinary user, the easiest way to repair the CPU is limited to the CPU pins are accidentally bent and then straightened, most of the CPU problems basically need to be returned to the factory for repair.

When a computer fails, it's sometimes hard to tell if it's the CPU or the motherboard. The following are some common ways to judge the disassembly:1

Observe the main scrambler light: When you turn on the computer, if the motherboard's light does not come on, it is very likely that there is a problem with the motherboard. 2.

Observe the fan: If the CPU fan is turning, but the computer still won't boot properly, then the problem may be with the motherboard. 3.

Processor upgrade: If you upgrade your processor and your computer won't boot, it's possible that it's a CPU issue. 4.

Sound when restarting: If you hear a brief "beep" when you start up your computer, it's most likely a problem with your motherboard. 5.

Check the power connection: If you're not sure if it's the CPU or motherboard that's wrong, you can check where the power supply is connected and try replacing some cables and plugs to see if there's any improvement. If the above methods cannot determine the fault point, then it is recommended to find professional and technical personnel for inspection and maintenance.
