The computer can’t start.

My general check is like this.

Now I don’t know what the specific problem is. There is no alarm sound, so consider the simplest problem first

For example, the memory bar is loose, or the motherboard cannot recognize the memory due to the oxidation of the gold finger. , at this time, unplug the memory stick, wipe it clean and then insert it again

Start the computer, usually this will solve the problem

If it still doesn't work, if you have an independent display card, you can also Wipe the gold finger after unplugging it as well. If the motherboard has an integrated VGA interface, you can use the motherboard's graphics card interface. After determining the problem, plug in the graphics card.

If the memory graphics card, If wiping doesn't solve the problem, don't panic. You can remove the S battery from the motherboard, cut off the power, wait a few minutes and then reinstall it.

Sometimes the S battery is caused by hardware changes. Configuration changes may also cause the computer to fail to boot

If none of these work, consider the motherboard or CPU problem

For CPU problems, first check whether the power supply is normal

< p> If the computer cannot enter the system when it is turned on, it can be divided into two situations: if the self-test fails but there is a hardware problem, if the self-test can pass but the desktop cannot be entered, it is a system or driver problem.

1. Can the self-test pass? , but cannot enter the desktop, it is a problem with the operating system or driver:

Why does the computer repeatedly restart and fail to enter the desktop normally or crash with a blue screen?

After ruling out viruses. , usually due to the installation of the GHOST version or other modified versions of the operating system. Because a large number of drivers that are not suitable for your hardware device have been integrated in advance, the system cannot correctly identify and load the necessary hardware devices for the system. .

Re-download and install the original image installation version of the operating system and install all drivers with Microsoft WHQL certification to correct such errors.

If you don’t want to reinstall, try it again Try booting F8 into safe mode and uninstall the incompatible driver of the hardware device (that is, right-click the device in the device manager)>Properties>The driver does not contain>Digital Signature Program>Microsoft Windows Hardware Compatibility Publisher driver ), after booting up, automatically recognize the hardware device, reinstall the driver you downloaded (WHQL) that has passed Microsoft digital signature certification, and then restart the computer again to see if there is any improvement.

Then there is the system It is caused by conflicts caused by software with duplicate functions (such as the installation of 2 or more anti-virus software and firewalls, advertising blocking).

If it is confirmed that it is not a system or software problem, you need to click The hardware is tested in the following order. The memory is most likely to be tested first, then the CPU, then the hard disk, and finally the graphics card. The motherboard will basically not have a blue screen.

In addition, you need to check whether poor heat dissipation is causing the machine to overheat (if so, you must install a more powerful radiator, re-coat thermal grease, and replace a powerful fan).

Check it out Check whether the top of the motherboard capacitor is bulging (if so, it must be replaced immediately).

It is also necessary to check whether the chassis power supply is insufficient, causing the output voltage to be unstable (if so, it must be replaced immediately)

If the power-on self-test fails and no "beep" sound is heard, there must be a hardware failure. A preliminary judgment is required from the alarm sound of the small speaker (buzzer) in order to narrow the scope of the hardware failure. Please refer to the specific meaning of the power-on alarm sound. Refer to your motherboard manual.

2. If the self-test fails, there must be a hardware failure:

What should I do if the computer starts the self-test but does not hear a "beep" sound? ?

If the computer fails to self-check after startup and does not hear a beeping sound, there must be a hardware failure.

1. The system time cannot be displayed and stored correctly due to insufficient battery power on the motherboard. This problem can be solved by replacing the motherboard battery with a new one, and pressing the DEL key to enter the BIOS after booting to reset the correct system time. Type of fault.

2. Check whether the motherboard capacitor is bulging or leaking. If so, you need to go to a professional computer repair place to replace the motherboard capacitor.

4. Reinsert all hardware and cables securely to avoid virtual connections.

5. Start it once with the case open to see if the fan is running normally. If it is not working properly, it needs to be replaced.

6. Check whether the power supply of the case is insufficient. If you have a replacement power supply on hand, try replacing it. Try.

7. Is there a hard disk failure and bad sectors? Enter the BIOS to see if the hard disk can be recognized.

8. There is no signal on the monitor, focus on checking the display part. If the connection status, black screen or blurred screen of the monitor may be the problem of the graphics card or the monitor itself.
