The computer has changed the CPU and restarted it repeatedly?

That means your motherboard is not compatible with the new CPU, in which case, if you want to upgrade, you have to change the motherboard. However, the current computer is not expensive, and it is better to buy a new computer in one step to change the motherboard.

1. Remove the motherboard and clean it with a toothbrush dipped in anhydrous alcohol, especially the CPU, memory, graphics card, power socket and rear socket; Erase the graphics card and memory row plugs with an eraser and clean them up. Dry thoroughly with a hair dryer.

2. Check whether the capacitor is bulging or not, and replace it if so; Check if the jumper is correct;

3. Clean the BIOS and measure whether the BIOS coin cell battery is less than 3 volts. Go into the BIOS again and re-optimize the settings.

4. The PD processor generates a lot of heat, and the heat dissipation cannot be sloppy.

This situation is generally a motherboard support issue.

Although the motherboard will support many models of processors, it may not be recognized if the BIOS is older.

You can look for the BIOS upgrade from the Internet and try again.

It's a strange question.

It stands to reason that the E3300 is a product released in the third quarter of 2009, and the E8500 is a product released in the first quarter of 2008.

If you buy this processor now, it must be second-hand, and it is best to test the processor itself on other computers. If you don't have anywhere to test, try upgrading your motherboard's BIOS to the latest version and then try the E8500.

As far as the description is concerned, it is recommended to check whether the various wiring is installed. This u is not supported by visual inspection. The motherboard is not supplied with power.

I don't know how to continue asking, satisfied.

It can't be that there is a problem with the power supply or that there is a problem with the changed CPU, or it may be a problem with the pins of the motherboard.

It may be that the motherboard does not support it, or the BIOS needs to be upgraded.

After replacing the CPU, the boot screen does not light up, many times we will encounter that after pressing the computer boot button, the computer cannot start, and there is no self-test or the phenomenon of entering the operating system, which often makes the user unable to deal with and affect the normal use. Here, we make a brief analysis of common fault phenomena, analysis and solutions, hoping to help users who encounter such problems. After pressing the power button, there is no reflection of the fault phenomenon:

After powering on, the screen does not show anything, and no "dropping" sound of the motherboard horn is heard. Fault analysis: The internal BIOS data of the COMS chip of the motherboard is damaged by CIH virus or static electricity, etc., and cannot be read, and the system cannot complete the self-test when it starts, so it cannot be started.

Known solution: Contact the motherboard manufacturer to replace the COMS chip with a new one or find the BIOS file provided by the motherboard manufacturer and write it to the burner. Fault Symptom:

After pressing the power button, the optical drive light flashes, the motherboard power prompt light is on, and the power supply is normal, but the screen has no display and no "drip" sound. Fault analysis: This phenomenon occurs after the CUP is damaged, the BIOS first checks the CPU during the self-test process, the CPU is damaged and cannot pass the self-test, and the computer cannot be started.

Known workarounds: Check if the CPU is installed correctly, check if the CPU core is damaged, check if the CPU is damaged using the replacement method, and replace the CPU if it is damaged. Fault Symptom:

There is no display when booted, and there is no prompt, the motherboard power supply is normal, the cup is normal, the fan is normal, but the screen is not displayed. There is no "drip" sound of passing the self-test. Failure Analysis:

After more than 3 years of use, the voltage of the battery that powers the BIOS settings gradually decreases, and data cannot be saved, and some motherboards that use early chipsets will not be able to complete the self-test, and there is no problem with the motherboard itself. Known solution: Buy the lithium battery of CR2032, replace the existing battery on the motherboard to complete the self-test normally, and then reset the BIOS parameters.

Fault phenomenon: After pressing the power button, the computer will automatically shut down or have no response. Failure Analysis:

In order to protect the CPU from the heatsink device, some motherboard manufacturers will not be able to boot up if the CPU is not installed, the CPU fan power cord is not connected to the CFAN interface of the motherboard, or the CPU fan is connected to the SFAN (the interface of the system fan). Known solution: Correctly connect the CPU fan to the power connector of the motherboard, and make sure that it is connected to the three-core dedicated CPU fan connector of the CFAN next to the CPU.

Fault phenomenon: After pressing the power button, the self-test cannot be passed, the display is not displayed, and the display indicator is orange or flashing. Failure Analysis:

Summary. Hello dear, happy to answer your <>

If your computer won't turn on after replacing the CPU, there are several reasons:1Improper installation:

After replacing the CPU, you may have forgotten to connect it to a power supply or have no accessories such as a heatsink installed. Check that all parts are connected correctly and that the heatsink and CPU are securely mounted. 2.

Power issues: The PC isn't functioning properly due to insufficient power or damage after replacing the CPU. It is recommended to use a high-quality power supply and choose the power reasonably.

Take a look at the manual to understand the basic settings for your new CPU, modify the settings, and if necessary, restore the BIOS to the default settings <>

The computer will not light up after changing the CPU.

The following are the related expansion roller stoves or <>< that I hope will be helpful to you

CPU incompatible: The replacement CPU is not compatible with the motherboard, or the motherboard BIOS needs to be flashed. You can check whether the motherboard model supports plugging in the CPU, and the boundaries of the BIOS that need to be upgraded.

Summary. There is also the power supply circuit is not connected, check the graphics card auxiliary power supply interface is loose, this is the most likely situation, and the system needs to be installed. The fan of the chassis power supply does not rotate because the power strip switch is not turned on or the chassis power supply has been damaged.

Faced with this situation, a new chassis power supply can be purchased to be replaced. With a little more hands-on ability, you can disassemble the chassis and use a multimeter to measure the voltage at the output end of the chassis power supply. If there is no output voltage, the case power supply is indeed broken.

Yes If the output voltage is correct, the case fan is broken.

After changing the CPU of the motherboard, the computer does not light up.

Hello, glad to answer your <>

The computer does not light up the memory module contact is poor, there is static electricity at the interface part Re-re-insert, the eraser memory module is incompatible, the slot location is wrong, you should use 2-4 slot memory modules to unplug the power supply first, empty the motherboard battery, and then turn on after a few minutes.

Hello, pro according to the description of the problem you provided: the possible causes are as follows:1

Power connection issues: First, you need to make sure that the power cord is properly connected to the power slot on the motherboard. Check that the power connection is complete and not loose or broken.

2.Power switch issue: Check whether the power switch is turned on.

Sometimes, we forget to turn on the power switch, which causes the computer to not boot. 3.Memory module issues:

If the memory module is not installed properly or is damaged, the motherboard will not boot. Verify that the memory module slot is inserted correctly and that the memory module is not damaged or in poor contact. 4.

CPU Issues: If the CPU is not installed properly or damaged, the motherboard will not boot. Please make sure that the CPU is properly installed on the motherboard and that it is not bent, damaged, or otherwise abnormal.

5.Graphics card issues: If you are using a discrete graphics card and it is not installed properly or is damaged, it can also cause the motherboard to fail to boot.

Please check that the graphics card is properly inserted into the PCI-E slot and is not damaged.
