CPU and motherboard issues, motherboard issues, power supply issues or CPU issues?

CPUs generally don't love bad.

What kind of CPU do you want to divide the situation you are talking about

Some models of CPU will rise to more than 70 degrees in 1 minute if the fan is not added to the boot partition.

Some CPUs are just a little hot even if they don't have a fan for 10 minutes, and they have a large range of boot without display.

It can't be judged by the CPU.

No display at boot mainly.

Power supply. Mainboard.

Graphics card memory.

Basically, it already contains all of the host, so just saying that there is no display on boot is not accurate at all.

It's hard to say, there could be multiple reasons for the problem, and it is recommended to flash the BIOS

Q1 Is your graphics card an integrated or discrete graphics card?

Question 2: It's strange that the CPU doesn't have a fan and it's not hot.

Question 3 First check whether the motherboard is powered on, then check whether the connector is secure, and then check whether the gold finger is dirty (wipe it off with an eraser or alcohol).

My question: I didn't understand your 4.

If you don't turn on the fan and thermal adhesive! Your CPU could burn out!

If only the computer could light up! (That is, as soon as the computer is turned on, the computer will "drop" sound) if the drip sound appears. Then your CPU should be good!!

Brothers! I advise you to buy a computer and go to a repair shop to find a professional! Otherwise, burning out the CPU is enough for you to feel distressed!!

There is no alarm on the PC horn, so it's hard to say what the problem is. You look to see if the motherboard and the chassis bottom plate are in contact, it may be caused by short circuits. You can take out the motherboard and put it on an insulated object only with the CPU, memory, and graphics card can be lit. If not, I suspect there is a problem with the motherboard.

1.The power adapter (charger) is broken, resulting in no power supply to the computer, but the computer battery supplies power to the motherboard for a short time, use a multimeter to check the voltage at the output plug of the power adapter, if the voltage marked on the adapter is too different or there is no voltage, replace the power adapter to try, if the output voltage of the adapter is normal, check it according to the following.

2. If the voltage difference between the electricity of the computer is too large or there is no voltage, try to replace the power adapter, if the output voltage of the adapter is normal, check and deal with it according to the following.

2. The power interface of the computer is not in good contact or damaged, when the adapter is normal, there should be a power indication and charging indication when plugged into the computer, if the computer is not displayed when plugged into the external power supply, it is a problem with the power interface or the power control of the motherboard, and it can only be sent for repair.

3. The motherboard has a short circuit and causes the power supply to protect the shutdown, this situation is the most serious, and the probability of replacing the motherboard CPU is greater, and the reason for this situation is that the computer fan is bad and causes heating and does not shut down.

4. If there is a spare battery, you can change to a normal electric battery to try to turn it on, so that you can judge whether it is a problem before the power supply of the host or after the power supply. If only the power adapter is broken, it is the easiest, you can replace it, and other faults can only be tested and repaired by a professional repair shop.

Motherboard and CPU are two different concepts, not the same thing.

Motherboard: also known as motherboard, system board, logic board, motherboard, baseboard, etc., is the center or main circuit board that constitutes a complex electronic system such as an electronic computer. A motherboard is usually installed in a chassis and is one of the most basic and important components of a computer.

The motherboard is generally a rectangular circuit board, and Changhuahe generally has BIOS chips, IO control chips, keyboard and panel control switch interfaces, indicator plugs, expansion slots and other components.

The function of the motherboard is to make the various components of the computer connected, simply put, to connect the power supply with various external chips and the chips that have been integrated with themselves. The type and grade of the motherboard determine the type and grade of the entire computer system, and the performance of the motherboard can affect the performance of the entire microcomputer system.

CPU (** processor): It is one of the main equipment of electronic computers and the core accessories in computers. It is a very large-scale integrated circuit, which is the computing core and control core of a computer, and the CPU includes computing logic components, register components, combinators and control components.

The main function of the CPU: It mainly interprets computer instructions and processes data in computer software. The CPU is installed on the motherboard, and the motherboard can be seen as the body, while the CPU is the heart.
