The boot card is in the self test, and the computer is stuck in the self test when the computer is t

If the card is in the self-test, it means that the BIOS and CPU are fine, and it may be that the memory, graphics card, and hard disk are faulty.

The landlord's graphics card is onboard, and the possibility of failure is very low, that is, memory, hard disk.

Sometimes it is stuck on the welcome screen, which means that the memory is fine, and it is generally the hard disk that has lost key system files and cannot enter the system.

Combined with the previous situation analysis, the hard disk light is on but does not flash when the card is in the self-test, which should be due to the corruption of some data in the boot area of the hard disk.

In summary, there may be bad sectors on the hard drive, resulting in the loss of some files.

Solution: It is recommended to separate the sectors with bad sectors from the low-level hard disk, and then re-partition the hard disk to avoid using damaged sectors. But for the security of the data on the plane, it is best to replace the hard drive.

Possible causes: unstable local voltage; The use environment is with strong magnetism; The chassis is vibrating excessively; Frequent illegal shutdowns, and so on.

P.S.: If the memory is faulty, the alarm sound of the boot buzzer should be three long sounds: drip-drip-drip——。

Generally speaking, the Windows interface can not be entered and the hardware is related, sometimes the card in the self-test is likely to be related to hardware damage, there may be memory oxidation, it is recommended to unplug the memory to wipe the memory gold finger, if not, replace the memory and hard disk to see if it can be solved. The CPU should be fine, but you can run it for a while and touch the heatsink with your hand to see if it's hot.

I think it's still a system problem, it may be a logical error in the hard disk that causes a problem with the system, it is recommended to reinstall the system to see the results.

I've been in this situation before.

My workaround:

All the internal wiring of the chassis should be reconnected, and I don't know if it is not connected there.

Sometimes it is necessary to connect several times, it is recommended to close the chassis after booting and inspection, or it is not troublesome to wire cable

Do I have to do this every time? Generally speaking, the computer will not be self-tested until it is shut down and restarted abnormally. After passing the self-test, the speed is normal.

It is caused by the unexpected shutdown of the system, and the percentage displayed above is normal from the C disk to the last disk After the detection is completed, it will enter the system You can also press the enter key to skip But there will be the next boot, just be a little patient and wait for it, boot self-test:

Also known as power on self test (post). Refers to the behavior of a computer system, powered on, (BIOS program), including testing of CPU, system motherboard, basic memory, extended memory, system ROM BIOS, and other devices. If an error is found, give the operator a hint or warning.

Simplifying or speeding up the process allows the system to start up quickly.

When your computer boots up, it performs a POST-ON self test to check if the hardware components are working properly. If your computer gets stuck during the self-test, it could be due to several reasons:

1.Memory failure: If your computer gets stuck while testing itself, it may be because of a memory failure. You can try replugging the memory module, or test it with a different memory module.

2.Hard drive failure: Problems with the hard drive can also cause the computer to get stuck during self-testing. You can try re-plugging the drive, or replacing the drive for testing.

3.External device failure: If the computer is connected to an external device during the self-test, it may be because the external device is malfunctioning and the computer is stuck. You can try disconnecting all external devices and then starting your computer again.

4.Motherboard failure: If none of the above methods can solve the problem, it may be because the motherboard is faulty and the computer is stuck. You can try replacing the motherboard for testing, or contact technical support for repairs.

If your PC's self-test gets stuck, you can try pressing the reset button on your computer's console or pressing the power button to force it to shut down, and then start your computer again to see if that resolves the issue.

1. Keyboard and mouse, the boot self-test will detect the mouse and keyboard, if there is a problem, it will cause the card to the self-test interface, the solution is to unplug the keyboard and mouse, check whether it passes the self-test, if it passes the self-test, replace the mouse and keyboard.

2. Hard disk and optical drive, the most likely is the hard disk and optical drive, the desktop needs to open the chassis, unplug the power cord of the hard disk optical drive to see if it passes the self-test, if it passes, further rule out the problem of hard disk or data cable.

3. If none of the above is true, then the most likely thing is that there is a problem with the motherboard BIOS and needs to be returned to the factory for repair.

There are times when our computer reboots and gets stuck on the self-test screen, what should we do? So let me tell you the solution to the computer reboot stuck on the self-test screen, I hope it can help you!

How to restart the computer and get stuck on the self-test screen:

The computer is stuck on the self-test screen, which is a sign that the computer cannot pass the self-test. There are many reasons why the computer cannot pass the self-test, the main ones are:

1. The memory bar is faulty, sometimes the computer is turned on and the silver has not been displayed, and sometimes the computer will emit a continuous beep sound when the computer is turned on. Even if the computer is turned on occasionally, sometimes the computer keeps restarting, like this is usually caused by poor contact of the memory bar or damage to the memory bar, please wipe the gold finger of the memory bar or replace the memory bar.

2. When the graphics card is faulty and the graphics card is damaged, the initialization of the graphics card will not be completed, and the screen will stay on the self-test page of the graphics card when it is turned on.

3. CPU failure, CPU generally rarely fails, but it is not ruled out. When the CPU pins are in poor contact with macros, or the CPU is burned due to high temperature, it will not be able to boot. Generally, if the CPU temperature of the computer is too high, the computer will automatically protect and turn into a blue screen or the computer will automatically restart, but once it is burned out, it is irreversible.

4. If the BIOS chip fails, the host will initially complete the loading of the BIOS program after powering on, and only after the BIOS itself is detected and loaded, the CPU will start to perform the self-test and boot process according to the program. If the BIOS does not pass the computer, it will naturally not be able to complete the self-test, and of course, the computer will not be able to boot normally.

The computer cannot pass the self-test when it is turned on, and it needs to be repaired. ‍

Attachment to the solution that the computer can't restart and shows no signal:

Check if the VGA data cable socket is loose!

In many cases, the data cable between the computer and the monitor is loose, and no signal is transmitted to the monitor.

Then check whether the VGA connector at the display and the VGA street at the host are loose.

Judging by the previous boot inspection!

In the past, after booting, the motherboard would generally "beep" to prompt that the boot was successful, and the boot self-test was completed.

If you hear that "beep" sound, it means that there is nothing wrong with your motherboard!

And the display has no display! Then it may be that the independent graphics card has an independent graphics card, which may be loosened and caused by the damage of the graphics card!

Solution: Replace the graphics card, connect the VGA data cable to the interface of the replacement graphics card to see if it can be displayed.

If you don't hear a "beep", then it may be caused by poor contact with the memory bar and CPU on your motherboard.

Solution: Of course, use an eraser to wipe the part where the gold finger is in contact with the motherboard, and then reinsert it to see if it can solve the fault.

ps: Many computer motherboards will not have the prompt sound I said even if they are turned on normally, so as long as the fan turns on this kind of motherboard after turning on, and the monitor has not received the signal, then you can also use this step to troubleshoot.
