Prove that your CPU is broken.,Because the landlord changed another motherboard and tried the CPU.,As for why the bad CPU heats up.,I'm telling you.,The bad processor will all heat up.,Unless you remove the CPU power up foot, it won't heat up.。

CPU fever means that your CPU is not broken, and it can tell you for sure that the motherboard is broken.

It's best to find out the cause of this phenomenon like yours by replacing it with hardware, and it's best to test it with a motherboard diagnostic card.

This can be done as follows:

1. Observe the indicator light on your case, see if it is on when it is turned on, and check your monitor power (socket) and power cord if it is on (try to change it). Don't light up and look below:

2. Open the case, turn on the computer, see if the CPU fan and graphics card fan are turned, the indicators on the motherboard and the hard disk indicator are not on, if nothing is running, check your power supply.

3. If the monitor and power supply are normal, check the motherboard, and try another motherboard (borrow it from a friend). If changing a motherboard doesn't work, try another CPU (you can borrow it from a friend). If you change the CPU, it's still not normal, and then change the graphics card (you can borrow it from a friend), but it doesn't work, change the memory module.

1. A typical motherboard can provide a series of joints for processors, graphics cards, sound cards, hard disks, storage, external devices and other equipment. They are usually plugged directly into the relevant slots, or connected with wires. The most important component of a motherboard is the chipset.

2. The chipset is usually composed of the north bridge and the south bridge, and some are designed with a single-chip microcomputer to enhance its performance. These chipsets provide a common platform for the motherboard to connect and control the communication between different devices. It also includes support for different expansion slots, such as processors, PCI, ISA, AGP, and PCI Express.

3. The chipset also provides additional functions for the motherboard, such as integrated graphics core, integrated sound card (also known as built-in graphics core and built-in sound card). Some motherboards also integrate IR communication technology, Bluetooth, and other functions.

Summary. There are many possible failures.

If the motherboard is not connected to speak, it is possible that the memory and graphics card are loose.

It is also possible that the power output is undervoltage, the north and south bridges of the motherboard are damaged, the CPU is damaged, the CPU is not powered on, etc.

When the computer is turned on, the power indicator lights on, but the screen does not show anything, and there is a chirp from the case speakers.

There are many possible faults, if the motherboard is not connected to the speak, there may be loose memory, graphics card, power output is undervoltage, motherboard north and south bridge damage, CPU damage, CPU is not powered on, etc.

Analysis: If the host indicator light is on or off, the screen is not powered on (the power indicator is not on), or the screen is powered on but there is no signal or "no sighal" is displayed, the former means that the power is not on or the connection is poor, and the latter is generally the memory module is not in contact. Recommendations:

1.If the monitor is powered on but no signal is displayed, turn off the power and turn on the case, plug in and unplug the memory module again, and wipe the gold finger with an eraser (the back of the thumb fingernail is also fine) in one direction, and then turn it on after installation. If you can't do it, then it's simpler:

You can kick the chassis with one foot (pay attention to the location: the front of the shell on the left and right sides of the chassis that does not have an interface at the back). If it's a notebook, you can't kick it, but it's the same for other operations.

2.If the above operations do not work, turn off the power and turn on the chassis, reinsert the graphics card, and plug in the data cable between the monitor and the graphics card. 3.

If the monitor is not powered on (the indicator light is not on), look at the back of the monitor, plug the power cord that connects to the monitor upwards, and check that the other end of the power cord is powered on to the outlet.

This situation is definitely a hardware issue.

Here's how you can do it:

After the power is off, open the case, and plug in the connections of all the devices inside the case, for example, the connection between the power cord and the motherboard, the connection between the memory and the motherboard, the connection between the CPU and the motherboard, and the connection between the graphics card and the motherboard. After dialing it down, clean it up, and then plug it in completely (mainly to clean up the memory and graphics card).

Then power on and turn on the computer, see if the fault is eliminated, if it still doesn't work, you have to use the elimination method to test the devices inside the chassis, the elimination method is the system minimization method, first install the hardware that can ensure the normal start of the system, and then add other hardware one by one to eliminate. (It is recommended to use a motherboard test card to detect which one is broken and which one is replaced), according to my previous experience, it can be ruled out by the plugging method.

If the problem persists, consider whether the motherboard or other hardware is broken. It is recommended to send it for repair.

The black screen of the monitor is not displayed, which means that the monitor has not received the display signal from the host graphics card.

1. Check the connection between the monitor and the graphics card, whether the contact is good.

2. Check whether the graphics card and the motherboard are in good contact, whether the graphics card is working properly, clean the gold finger of the graphics card, and try to plug and unplug it again.

3. Check that the host is not turned on normally due to problems such as poor memory contact (the hard disk light does not jump, and there is no sound entering the system [if there is a speaker]).

4. Try to connect the host to another monitor, if it does not light up, it proves that it is a problem with the host, and use the replacement method to check the graphics card, memory, and motherboard to find out the damaged hardware.

5. If you can display it when you connect to another monitor, it is still the same if you replace it with the original monitor, and the display is damaged and needs to be repaired.

If there is a single display or an integrated display, do not connect it to the output of the integrated display.

See if the VGA cable connecting the monitor to the host is loose or broken, if it still doesn't work, try to unplug the VGA cable, see if the display shows no signal or English sign out, if not, there is a problem with the monitor, if there is no signal sign out, try to press ESC immediately after booting

Try to be compatible with the resolution.

If your display has two wires (power cable and signal cable), you check the power cable, if the light on the display flashes and flashes, it means that the power cable is fine, and you check whether the signal cable on the display screen is not connected; If the above two steps are fine, you can change the display to another computer to try it, if the display is normal, it means that the display is fine, and you can do other things!

1. Please check whether the connection between the monitor and the host is correct or stable;

2. Check whether the display is normal;

3. Pay attention to whether the motherboard is self-checking when booting up, and there is a self-test sound.

4. Check whether the fingers of Huina graphics card Jin Wu Bixiang are damaged;

5. Check whether the contact of the memory module is good, and wipe it with a dry eraser before using it;

6. As a last resort, take out the CPU for one minute and reload it to ensure that the installation is good;

7. If it still can't solve the problem, it may be a hardware failure, which is beyond your technical ability.

1. Check whether the power adapter is faulty. Replace the adapter.

2. Whether the fan works after turning on and whether the motherboard has power. Detect the motherboard and consider the power connector fault.

3. After turning on the machine, listen carefully to whether there is a prompt sound for entering the system. If so, consider the fault of the monitor cable and replace the cable.

4. Consider the failure of the screen background lamp. Replace the lamp.

5. Consider screen failures. Replace the screen.

6. Motherboard failure. Repair the motherboard.
