The computer suddenly broke after booting, and the computer kept restarting.

You look at the monitor, is it not plugged in?

If you are sure that the computer will not start. This problem is mainly due to the power supply and motherboard. It is recommended that you take your computer to the Drum Tower to see wow. Because the specific situation has to be analyzed on a case-by-case basis.

The computer can't be turned on, and the steps to solve it are as follows:

Focus on checking the connection line of the monitor to see if the line is well connected. Check whether other lines, such as the power cable (including inside and outside the chassis) and the data cable of the hard disk in the case, are connected correctly (if the disk is loose and cannot be detected, the system will not be able to boot).

Determine where the fault is based on the startup sound:

1. Short: The system starts up normally.

2 Short General Error, please go to CMOS Setup to reset the incorrect option.

1 Long 1 Short RAM or motherboard error.

1 long 2 short display error (monitor or graphics card).

1 long 3 short keyboard controller error.

1 long 9 short motherboard flash ram or EPROM error (BIOS corruption).

Constant ringing (long sound) The memory is unstable or damaged.

The power supply keeps ringing, and the monitor is not properly connected to the graphics card.

Repeat the short ring of the power supply.

No sound, no display power.

Reboot stops at the brand machine detection screen, you can press the keyboard tab key to see exactly where it is detecting.

For example, hard drives, optical drives, keyboards, etc., according to you, hard disks are probably the largest.

Open the side cover of the main computer. Unplug all the memory, erase the gold finger with an eraser, and plug it in.

If the above steps do not solve the problem, it is recommended to reinstall the system, or consult a professional to repair it.

It may be that the temperature is too high and burns out the motherboard.

Is the host responding? Is there a sound in it?,See if the memory module or something in it is loose?。。。

The computer keeps restarting, usually because of the driver or graphics card. The driver can be directly fixed for graphics card issues. Remove the graphics card and wash it with alcohol. If your computer is too old, just get a new one.

Have you changed anything recently, such as drivers, or installed any software?

1. Restart the computer, press F8, and the selection menu will appear.

2. Select the last correct configuration, try the safe mode, if you can enter the safe mode, you can uninstall the recently installed software or driver.

3. If this is still the case, you can only redo the system.

If you don't see the picture, you can't tell.

The motherboard general fault maintenance judgment is about 30-40 yuan. If the chip is broken, for example, the North and South Bridge is broken, it will be expensive. 200 can reap your dryness.

It depends on whether this north-south bridge is good or not. If it's an older motherboard, it's better to buy a second-hand one.

Motherboard faults can be divided into power supply failures, total mu balance line faults, component faults, etc. The main causes of motherboard failure include: 1. Component reasons:

The quality of the chipset and other components on the motherboard is not good, which causes the motherboard to deteriorate and damage, resulting in the failure of the motherboard. 2. Human reasons: When using the computer, hot-swap hardware at will or touch various connectors with metal objects indiscriminately, resulting in motherboard failure.

3. Dust and static electricity causes: due to dust or static electricity, the motherboard is in poor contact, short circuit or burns the motherboard judgment chip, resulting in the failure of the motherboard. 4. Causes of poor contact:

Due to rust, oxidation, weakened elasticity, pin desoldering, breakage, etc., various chips in the motherboard are not in good contact with each other, sockets, and interfaces, resulting in motherboard failure.

Motherboard maintenance is generally that price, whether it is new or old, not scum stupid to know what motherboard you are using, if it is older, it is recommended to buy a new one, generally not expensive, if the new buy not long or may have a warranty, this does not require you to pay a lot of silver.

The computer suddenly went black and the screen didn't necessarily mean that the motherboard was broken, such as Heng accompanied you to him, if he saw that you were not very good, he might say something crazy, causing you to panic, you had better find someone you think is good at it to show you.

Is this what Technician Xianji asked? If it's broken, I'll notify you, brother. It's not bad, drink the northwest wind. Yesterday there was another person who said that it was funny before shouting. It is said that the computer has not been used for more than ten years. I said, what have we eaten for more than ten years, and what have manufacturers eaten.

Common fault diagnosis methods for motherboard (motherboard failure can lead to power-on, power-off and shutdown faults):

The structure of the computer motherboard is relatively complex, the failure rate is relatively high, and the fault distribution is also scattered. According to the source of the fault, motherboard faults can be divided into power supply faults, bus faults, component faults, etc. The main causes of motherboard failure are as follows:

Component causes: The chips and other components on the motherboard are of poor quality, resulting in aging and damage to the motherboard, resulting in motherboard failure.

Human reasons: When using the computer, hot-swap the hardware at will or touch various connectors indiscriminately, resulting in the failure of the motherboard.

Dust and static electricity causes: The motherboard malfunctions due to poor contact of the motherboard, short circuit, or burning up the chips on the motherboard due to poor contact of the motherboard or static electricity.

Causes of poor contact: Due to rust, oxidation, weakened elasticity, pin desoldering, fracture and other reasons for poor contact with various chips, sockets and interfaces in the motherboard, resulting in motherboard failure.

According to the characteristics of the motherboard and the cause of the fault, when the motherboard fails, the diagnosis method of the motherboard fault is as follows.

Step 1: First of all, carefully observe the various slots, fans, chips, etc. of the motherboard for signs of damage: whether there is burning, burning, blistering, broken wires on the board surface, corroded sockets, and capacitor bursting

Whether the BIOS battery is charged or not. If there is obvious damage, it is necessary to carry out targeted repairs.

Step 2: If there are no obvious signs of damage on the motherboard, then use a soft brush to clean the dust of the motherboard, and check whether the motherboard is normal after cleaning. If it is normal, it is a fault caused by dust.

Black Screen Issue: Hope it helps:

There are many reasons why a computer has a black screen, and the common ones are:

Shows poor contact of the data cable;

There is no power supply to the motherboard;

Poor graphics card contact or;

Poor CPU contact and overheating; "It is strictly forbidden to copy and repost, the eagle of the Gobi Desert".

Poor contact of memory modules;

poor power performance;

Machine infection. cih

Viruses, BIOS

is destructively refreshed.

Microsoft black screen, please patch.

Most of these problems are the relationship between the memory and the graphics card, loose or poor contact, just move it or use the eraser to wipe the gold finger of the interface

You give it a try first. After shutting down. Clear the settings in the BIOS. See if you can turn it on.

Or you can physically disconnect the power button of the computer and then plug it in. Here press the power button again to see if it can be turned on.

It feels like there's something wrong with the computer's power supply. , if nothing is successful after replacement. That can only be the south bridge of the main board.

Power control. module.

That's right. Incidentally. Your computer won't boot after you pressed the power button. The host did not respond or pressed the power button after pressing the button. The fan spins and the machine won't start?
