What s wrong with the startup not responding? Is there currently no response to the start?

Since the invention of the first computer, computer technology has been improving every day, and the progress of computer technology has also greatly changed our lives and made our lives more convenient. We can use the computer to do many things, such as work, study, entertainment, shopping, and so on. It is precisely because of the full popularization of computers that we can truly achieve without leaving home.

But sometimes there will be some failures in the computer, such as the computer boot screen does not respond, today I will teach you 4 tricks, if the computer boot screen does not respond, what should we do.

1. Check whether the plug of the display screen is plugged in.

Don't think I'm doubting everyone's IQ, but it's true that many people forget this step, don't plug in the display screen, turn on the host, and find that the display screen doesn't respond and think the computer is malfunctioning, so when you encounter the display screen not responding, first confirm whether the plug of the display is plugged in.

2. Check the connection cable between the host and the monitor.

If the connection cable between the host and the display is bitten off by a mouse, you need to replace a connection cable, which is relatively cheap, generally about ten yuan.

3. Check if the graphics card is broken.

If it is not for the above two reasons, it may be because there is a problem with the graphics card, if there is a problem with the graphics card, then it may be a little troublesome, if you have a computer foundation, you can directly change a graphics card and plug it in to try it, if it is a computer novice, you don't know anything about the computer, then you can only ask professional technicians to come to the door to repair, and the replacement of the graphics card is generally about a few hundred dollars. If it still doesn't respond after changing the graphics card, it may be the fourth problem.

4. Problems with the display itself.

If it is not for the above three reasons, it can only be that the display screen is broken, and if the computer display screen is used for a long time and is not well maintained, it is easy to age and burn out. If the display screen is broken, it is recommended not to repair it, just replace it with a new display screen, a new computer display screen is only about 800 yuan, if it is repaired, it is not cost-effective.

Seeing this, I believe that everyone has already dealt with the failure of the computer boot display screen does not respond. In short, it is a simple troubleshooting by yourself, if there is no way, you can only ask professional maintenance personnel to provide door-to-door service, you should also pay attention to the basic maintenance of the computer when using the computer, so as to extend the service life of the computer. The above mainly teaches you how to solve the fault that the computer boot display screen does not respond, I hope it will help you.

If the computer does not respond when it starts, it is generally necessary to look at the hardware, and generally only if there is a problem with the hardware, there will be no response to the startup. If it can be started, English letters will pop up during the startup process, so it generally depends on the software, which is likely to be caused by software problems.

If the startup does not respond, it may be caused by a problem with the starter line.

This may be a malfunction of the computer hardware, it is recommended that you go to the after-sales service to deal with it.

<> first case is that the computer is completely unresponsive, that.

There is a computer case that has been turned on, but it is displayed.

If there is no problem with the above, then it may be the motherboard cable.

It could also be due to memory or graphics card cheating.

Summary. Hello, the car can not start this situation, is divided into two aspects, the first is that the vehicle starts without any response, then this situation 1: first of all, you need to check whether the battery power loss caused by this phenomenon?

If the battery is out of power, you need to charge the battery or replace it with a new one. 2: In the case of making sure that the battery does not lose power, focus on checking whether there is a problem with the vehicle starter or whether the anti-theft is locked, 3:

If there is a problem with the starter, you need to check the corresponding control circuit of the starter or replace the starter. 4: If there is a problem with the anti-theft system, you need to re-do the anti-theft matching.

The second major aspect is that the vehicle engine can rotate, but does not catch fire, then this situation focuses on checking, 1: whether the gasoline pump oil pressure is insufficient or the vehicle engine is not ignition, 2: if the pump oil pressure is insufficient, this situation needs to replace the gasoline pump.

Check the fuse or wiring of the gasoline pump. 3: If it is not ignited, focus on checking the crankshaft position, sensor and ignition coil.

Your bureau believes that the car can not start this situation, is divided into two aspects, the first is that the vehicle starts without any response, then this situation 1: first of all, you need to check whether the battery loss of Tong Jian wheel electric caused by this phenomenon? If the battery is out of power, you need to charge the battery or replace it with a new one.

2: In the case of making sure that the battery does not lose power, focus on checking whether the vehicle starter is a problem or whether the anti-theft is locked, 3: If there is a problem with the starter, you need to check the corresponding control circuit of the starter or replace the starter.

4: If there is a problem with the anti-theft system, you need to re-do the anti-theft matching. The second major aspect is that the vehicle engine can turn, but it does not catch fire, so this situation is to focus on checking, 1:

Is it that the fuel pressure of the gasoline pump is insufficient or the engine of the vehicle is not ignition, 2: If the pump oil pressure is insufficient, the gasoline pump needs to be replaced in this case. Check the fuse or wiring of the gasoline pump.

3: If the sail is not ignited, focus on checking the crankshaft position, sensor and ignition coil. The above two aspects are the relevant reasons for the vehicle to not start, as well as the solutions, it is recommended to make a relevant reference!

Drain the battery from being out of power.

What models have been inspected and repaired, and what is the reason for this phenomenon?

07 Focus.

The battery is fine, use the computer to read the fault code to see if the system is faulty.

What's going on when the starter doesn't respond? The reasons why the starter does not respond: 1. The control line of the starter is faulty; 2. There is a problem with the starting mechanical brush; 3. The battery does not have enough power; 4. The starting relay is faulty; 5. Start the insurance burns out.

The function of the starter Mu Zen is that when the key hits the position of the starting air, it converts the electrical energy into kinetic energy, so as to start the engine. The composition of the starter is: 1. Motor:

The motor used in the starter is a DC series motor, which converts the electrical energy input from the lead-acid battery into mechanical energy to generate torque; 2. Transmission mechanism: It is composed of a transmission sleeve, a one-way clutch and a driving gear, and its function is to transmit the electromagnetic torque of the motor armature to the engine flywheel to start the engine when starting; 3. Control device: also called electromagnetic switch, the purpose is to turn on or off the starting current, so that the driving pinion can mesh in or out of the flywheel tooth ring.
