What s going on with the computer sometimes having a white screen that doesn t work

If you can, try it on a different graphics card!

When this happens, it should be resolved from the following two aspects:

1. Software.

Check the system with anti-virus software to see if there are any viruses. Some viruses are capable of infecting or damaging some system services or drivers, causing some hardware to malfunction.

Check to see if you have installed any software that conflicts with the graphics driver. If so, it is recommended to reinstall the graphics driver.

2. Hardware.

Each component on the book is often damaged due to bad factors such as aging, poor contact, dust, and damp environment, which affects the normal use of its function, and even affects the service life of the component in serious cases. The phenomenon of a white screen in the book,There may be a reason for this,But it's not guaranteed.。 It is recommended to go to the after-sales service to check the hardware situation.

To find out the specific cause of the white screen, you can start from the above two points: check the software first, this will not bring a monetary expense. Then go to the after-sales service to see if there is any problem with the hardware.

If the problem is not solved by the above two steps, you can submit further information for further analysis of the cause of the problem. Or optionally reinstall the system.

Failure of the graphics card.

The reason for the white screen, 90% is due to the problem of the graphics card, you open the case, check whether the capacitance of the graphics card is bulging, whether your CPU is overclocked, whether the graphics card is overclocked, unplug the graphics card and plug it in again!

It could be that it was too tiring.

Let it rest hehe.

The general display problem is a problem with the graphics card.

I don't know when you got the white screen.

If you go into windows before it appears.

That should be a software issue, you can update the driver or reinstall it.

LZ: You're in a good situation.

It may be that there is a quality problem with the interface or wiring on the monitor! Try replacing the wiring or re-connecting the connectors! And lz, is the computer you bought a motherboard integrated graphics card or a discrete graphics card!?

If you've tried the wiring and connectors, it's probably a problem with the graphics card on your motherboard! In this case, I suggest you don't move anything! For the dealer you bought the computer contact their maintenance staff to come to the test!

It's so convenient and guaranteed! No, let them help you replace the new accessories casually!

Oh, it's very easy to do, try to look at the screen on a different computer, if it's the same, it means it's not a computer problem.

Under normal circumstances, the cable in the display is broken, the wire is a row of wires connected to the circuit board and the screen, you can change one, go to the repair shop to change, but I can tell you that you don't have to spend more than 100 yuan, so you have to bargain, to prevent the repair shop from blackmailing you, in the electronic market that the cable is directly bought is about 2 yuan 5 yuan, I sleep no more than 100 is there also the shell fee of the electrical appliance store labor fee or something, after all, you said that as long as 5 yuan of the cable others are not willing to repair ah, hehe,

I think it's best to find customer service quickly, they have an obligation to help you solve this problem, don't mess around with this problem yourself.

1.Is the graphics card, CPU, and memory overclocked? reduce frequency;

Loose memory sticks? Check it, you can remove the CPU and other hardware, and then put it together, remember to unplug the motherboard battery.

The failure of the white screen of the computer is basically caused by the graphics card and its driver, so start from this aspect to check.

Causes and solutions for white screen when computer boots:

1) First of all: Before doing it, check whether the connection between the host and the graphics card is loose, and re-plug it, sometimes this will also cause a white screen.

b) There are two main reasons for the white screen of the computer to boot up:

The first reason is that the slot between the graphics card and the motherboard is not fully contacted, resulting in the white screen phenomenon, as long as the power is turned off, the chassis is opened, the graphics card is taken out, and the eraser is aimed at the gold finger to wipe it a few times, and then reinstall it back, sometimes it is handled like this, and it is good to reboot the computer, if it is not good to deal with it in this way, the performance of the main chip of the graphics card is reduced, and the video memory is soldered, which leads to the white screen of the display, and the graphics card is repaired or replaced, <>

The second reason, which is the problem of the LCD screen, generally occurs because of the phenomenon of bulging and discharging of the filter capacitor at the output end of the power supply circuit, leakage, and insufficient power supply of the driver board circuit, virtual soldering of the MCU core and the main chip, poor contact of the screen line, and the main chip of the screen circuit is soldering, insufficient power supply, or damage, and the horizontal or hard line caused by it, and it may be that the power supply insurance of the LCD circuit is damaged, which will cause the white screen phenomenon. Solution:

Jianyi sent after-sales or LCD maintenance department to repair the display, of which the screen line is most likely to have poor contact, <>

3) Detection method: The judgment of this phenomenon is to borrow someone else's good monitor to try it, and you can see the operating system, which means that there is a problem with the display, if you can't see the system, someone else's display is also a white screen, this is the problem of the graphics card, and you can replace the graphics card.

Summary. Hello dear, there may be several reasons for the white screen of the computer:1

Graphics card or monitor failure: Graphics cards and monitors sometimes fail to boot properly due to malfunctions, resulting in a white screen. 2.

Hardware failure: The motherboard, memory, hard disk, and other components in the computer may also malfunction, causing the white screen problem. 3.

Software problems: Usually the problem of the white screen of the computer on boot may be caused by problems with the operating system software, such as the corruption of the operating system or the corruption of the driver. 4.

Virus infection: If the computer is infected by malicious viruses or Trojan horses, it will also cause the system to appear white screen and cannot be turned on.

Hello dear, there may be several reasons for the white screen of the computer:1Graphics card or monitor failure:

Graphics cards and monitors sometimes fail to boot properly due to malfunctions, resulting in a white screen. 2.Hardware failure:

Components such as the motherboard, memory, and hard disk in your computer can also malfunction, causing a white screen problem. 3.Software Issues:

Usually, the problem of the white screen of the computer when it is turned on may be caused by a problem with the operating system software, such as the damage of the operating system or the damage of the driver. 4.Viral Infection:

If the computer is infected by a malicious virus or Trojan horse, it will also cause the system to have a white screen and cannot be turned on.

Dear, you can try to operate it and see if it can solve your problem.

The internal problems of the display mainly include the problems of the LCD panel drive circuit, the LCD panel power supply circuit, the poor contact of the screen cable, and the problems of the motherboard control circuit.

The white screen after the display is turned on, indicating that the LCD panel does not get the drive signal, if you regret the laptop.

The switching signal is usually sent through several transistors.

to control, so the fault may be a damage to the transistor that controls the switching signal.

Precautions for computer repair.

In the process of reproducing the phenomenon of faults and judging maintenance, the expansion of the scope of faults should be avoided.

If the output voltage of the DC-DC voltage conversion circuit is normal, there are damaged capacitors and other components between the output end of the DC-DC voltage conversion circuit and the screen cable interface, and the damaged components can be checked and replaced.

It should be noted that if the power supply voltage of the screen cable interface is normal, then check whether the timing signal and drive signal in the LCD panel drive circuit are normal. If it is abnormal, check the output signal, input signal and power supply voltage of the chip that generates this signal respectively to determine whether the driver chip is damaged. If it is damaged, it can be replaced.

Encyclopedia - Computer.

The white screen of the computer may be caused by the failure of the driving circuit of the LCD panel, the failure of the power circuit of the LCD panel, and the poor contact of the screen wire.

Poor or faulty graphics card contact will cause a white screen on the computer, just check the graphics card or replace it with a new one.

Loose memory modules will also cause a white screen on the computer, so you can pull out the memory module, clean the slot, clean the memory module, and then plug it back in.

Summary. What is the problem with a white screen on the computer.

1. It may be that the graphics card is not plugged in properly, after removing it and wiping it clean, clean the slot, and reinsert the graphics card after cleaning it. 2. It may be that the screen cable interface connected to the computer screen is loose, and the screen cable can be reconnected. 3. It may be caused by poor heat dissipation, you can dust and oil the fan in the case, or replace the fan.

4. It may be because there is too much dust in the chassis and poor contact, and the chassis needs to be cleaned in time.
