The display is not clear what to do if there are snowflakes

There are only two possibilities,One is the display failure,It is recommended to use the replacement method,Put your monitor on another computer to try it,One is the graphics card,Eliminate the soft fault first,That is, install the driver that comes with the graphics card,Some are the ghost version of the universal driver,If it can't be solved,It is also recommended to use the replacement method,This can basically determine the fault。 However, once my friend's screen was also a little unclear, but after I cleared the dust in the machine, troubleshooting, maybe it was a coincidence, you can also give it a try! Maybe there's an unexpected discovery!

Workaround:1Splash screen is a relatively common display failure, and most of the screen failures are caused by the graphics card itself.

If you can occasionally enter the system or enter safe mode (F8), first reinstall the graphics card driver; Then it is to clean up the gold finger, which can generally be solved.

If the system can't get in, it is very likely that the video memory is damaged, and often when the system starts, there will be a blurred screen of confused characters, in which case the graphics card or video memory bar must be replaced.

2.If the temperature is too high, the fan of the graphics card is not good, or the air duct in the case is not good, resulting in too high temperature, and the temperature is high in summer, which is more common;

Feel the temperature of the memory chip with your hand to check whether the fan of the graphics card is stopped. Then look at the AGP slot on the motherboard to see if there is any dust, check whether the gold finger of the graphics card is oxidized, and then clean up the dust according to the specific situation, wipe the gold finger with an eraser to polish the oxidized part.

3.The power of the power supply is insufficient. If there was nothing wrong with it before, this can basically be ruled out.

It may be caused by the poor contact between a cable connecting the control board inside the display and the LCD panel, so go to the after-sales service to test it!!

There are two possibilities. First, the picture tube is aging; The second is the counter-tide.

What to do if the computer monitor has a blurred screen.

If you can ask for after-sales in less than a year, you should be able to change.

There are two ways to solve it. Here's how:

Method 1. 1. One of the reasons for the snowflakes on the computer screen is that the resolution changes too high or too low, resulting in failure. The solution to this reason is to open the computer and right-click on the blank space of the desktop, and the screen resolution appears.

2. After clicking, a selectable resolution range will appear, choose a value suitable for your computer, and take the clarity of the computer screen as the standard. OK to save.

3. Debug the screen refresh rate of the monitor, if this value is too low or too high, it will cause the clarity to change. The debugging method is as follows: right-click on the blank space of the desktop, screen resolution. Advanced settings, a box for the monitor appears.

4. Debug the size of the screen refresh frequency, see if the screen has changed while adjusting, and debug the size according to your actual situation.

Method 21: If the above methods do not work, check whether the cable behind the computer is loose, take it out and plug it in again.

2. If it still can't solve the problem, try it with a new connection line, <>

No signal on the display solution:

1. First of all, we conduct a comprehensive check on the connection between the computer monitor and the host, and plug each connection back to see if there is a connection problem.

2. If the fault still exists, then we need to open the chassis to see if the chassis contains metals and other substances, causing a short circuit in the computer host circuit, and then we smell the computer to see if there is a burning smell, and see if there are damaged components around the motherboard and around the CPU.

3. After checking the whole chassis, there is no abnormality in the chassis, then we will dust the chassis.

4. If it can't be turned on, then use the minimum system method, unplug the data cable of the hard disk, floppy drive, and optical drive, and then check whether the computer can be turned on. Then connect the above devices to the computer one by one, when connecting a certain device, the fault will recur, indicating that the fault is caused by this device, and finally focus on checking this device.

5. If the fault still exists, it is likely to be the fault of the memory card, graphics card, CPU, motherboard, etc., at this time, we only need to plug and unplug these hardware, or replace it again, and try to find the cause one by one.

6. If the memory, graphics card, CPU and other devices are normal, then discharge the BIOS, use the isolation method, place the motherboard outside the chassis, connect the memory, graphics card, CPU, etc. for testing, if the computer can be displayed, then install the motherboard into the chassis for testing until the cause of the fault is found. If the fault persists, you need to return the motherboard to the manufacturer for repair.

7. When the computer is turned on and started, the system BIOS starts to POST (power-on self-test), and when a fatal error is detected in a device in the computer, it will control the speaker to send out a sound to report the error. Therefore, there may be a fault that the power is turned on without displaying an alarm sound. If the computer is turned on and there is no alarm sound, the fault can be checked according to the meaning of the BIOS alarm sound to check the faulty device to eliminate the fault.
