The computer often can t enter the system with a blurred screen, or restarts or crashes with a black

It shouldn't be a compatibility issue.

Personally, I think it should be magnetized, so if you have a printer next to you, use the buttons of the monitor to degauss.

There are basically four reasons for this: 1. Troubleshoot the monitor first, and test the monitor on another host. 2. Go to the official **** of the graphics card for an up-to-date driver.

3. It is the fault of the graphics card itself, which will occur in the graphics card heatsink. Many people don't understand why the colder the weather is not good for heat dissipation, this is because when it is first started, the lubricating oil in the graphics card fan becomes sticky and cannot reach the best speed in time. Affected heat dissipation function.

4. Related to the weather, the normal use temperature of the computer is between 5 degrees and 40 degrees, it is recommended to change the environment to test.

There are the following reasons for your division to investigate:

1. If there is a problem with the graphics card, first dial out the graphics card and clean it up, reinstall it and try it, but if you can't find a good graphics card and install it, try again;

2. Power supply problems, try it again;

3. Memory problems are handled in the same way as 1.

Does your computer have 360-degree security guard? If there is, it will be solved.

Yours is an assembly machine, right? The assembly machine loves to have this problem, a common problem

Why is the brand machine expensive? What is sold is compatibility The assembly machine says that everything that is matched for you is compatible. In fact, there are all faults. No way. If you want to **, you have to find the one that sells your computer and let him give you the whole.

If you have no professional computer experience, it is not recommended that you disassemble the case. You sell the computer ** and ask him what's going on. Don't dismantle the computer yourself, if something really goes wrong, they'll be a scoundrel for you.

If you have a problem with the graphics card, dial out the graphics card and reinsert it first.

It should be that heat dissipation is not good.

Causes the video memory to overheat.

A blurred screen appears.

The graphics card is overheating, or it is loose.

To put it mildly, after yours enters the water, it is generally dried with hot air, and even then you need to add some professional oil. And the keyboard won't break.,It can only be said that it's caused by water on the motherboard.,The flower frequency may be a bridge or graphics card with a breakpoint.,Let me say I'm not a god either.,You take it to the maintenance station to check.,The data that comes out of the machine is scientific.。

If it is helpful to you, please remember to accept it as a satisfactory answer, thank you! Have a great day!

Every mistake has a specific fault**, just like the license plate number. If it is a blue screen, you can record the blue screen error**, and then find the root cause of the error based on this error**. Bugs** are explained in detail online.

Blurred screen is a graphics card problem! The blue screen is a hardware compatibility issue. I think you should go and change your graphics card.

The memory should be fine. You're an old computer after all. Now this graphics card has been discontinued.

The ones that are sold to you are generally repair cards or second-hand. So it is recommended that you go for a different graphics card. Of course, there will be good repairs.

It's not all unavailable.

The landlord has the same problem as me Sometimes I can't turn on the computer for several hours It is recommended that you unplug the memory, and then wipe the memory slot with a piece of hard paper, and then use a hair dryer to blow on the memory slot, hot air, blow for about five minutes, and blow back and forth Then plug in the memory module and try it I don't know what board your board is, and I don't know how many slots there are, if it is four slots, then you can change two slots to try Mine is how good it is, and now there is no problem The board is caused by moisture

Clean up the memory and graphics card slots The old machine should be a slot problem The main thing is that the contact shrapnel in the slot has decreased for a long time There is no problem with the new accessories plugged in There will be poor contact if there is dust in a few days Just plug in and unplug it again It will not work in a few days.

1.If the graphics card is in poor contact with the motherboard, please wipe the gold finger of the graphics card with an eraser, and brush the graphics card slot with anhydrous alcohol, which can generally solve the problem of blurred screen.

2.If the above method is still a blurred screen after trying, then there is a fault in the graphics card itself, for example: oxidation of various components of the graphics card or aging of a certain component, more serious may be the graphics card's graphics card memory chip, BGA has a problem of poor contact, this situation is worse, maybe the problem of the blurred screen can be temporarily solved by BGA welding of the video memory chip, but it is not a long-term solution, if the faulty graphics card is not too high-end, it is recommended to replace it.

Method 1Unplug the graphics card and memory and plug it back inMethod 2Reinstall the software, all of the above fail, that is, there is a problem with the hardware, and the hardware is replaced.

Hello, I am the chief engineer of color computer, and your problem has the following two situations: The blue screen is caused by the poor oxidation of the gold finger of the graphics card, and the poor contact leads to data transmission errors, and the blurred screen is the chip soldering point of the graphics card GPU, which is loose due to high temperature, you can try to blow on the GPU with a hair dryer, when it is hot, press down on the GPU and release it after a few minutes, the position of the GPU is under the graphics card fan, and some are under the radiator. However, most of these problems are not easy to repair due to the aging of the graphics card, and replacing the graphics card can completely solve this problem. Color Computer Engineer Fan Min.

Blurred screen, it's a graphics card problem. Unplug it and erase the gold finger under the video memory with an eraser. Then blow the dust out of the motherboard's graphics card slot.

Finally, plug the graphics card back in and see if it works. If it's still a blurry screen. That is, the graphics card needs to be replaced.

In your case, you try to turn on the computer again after a while, if it can be turned on normally, consider whether there is a problem with the capacitance of the graphics card in this situation, unplug the graphics card to see, if it still doesn't work, in this case, consider replacing the memory module or the graphics card.

The solution to the problem that the screen often appears when the computer starts:

1. Due to poor heat dissipation of the case, the screen caused by the temperature of the graphics card rises.

The solution is to eliminate heat dissipation issues.

2. The solution caused by the graphics card or monitor does not support high resolution:

1) Restart the computer, press the F8 key continuously, pop up the advanced boot menu, select enter to enter the "Safe Mode" to log in to the alarm cover system, then enter the display settings under Windows, select the 16-color state, click the "Apply" button, and click the "OK" button.

2) Restart the computer, in Windows normal mode, enter the Device Manager, delete the graphics card driver, and restart the computer.

3) The graphics card is loose, and unplugging the graphics card and reinserting it after shutting down usually solves the problem.

4) The system is overheating, including the CPU temperature is too high and the graphics card chip is too hot. You can install cooling fans in the appropriate locations in the case, or place the case in a well-ventilated area.

Solution for the blurred screen that appears after the attached computer is turned on:

Step 1: Don't panic when such a problem occurs, analyze it slowly, generally from the first point, whether the display has been squeezed, impacted, etc., if not, look down! ~

Step 2: Take a look at the temperature of the graphics card, if the temperature is too high, it will also blur the screen, a while ago my laptop was overheated, after the screen was blurred, the independent graphics card was burned! (Based on the current system configuration, this is likely to lead to).

Step 3: Win7 and Win8 system will hardly appear, XP system almost open the software is noisy, and it is easy to get stuck in the blue screen if you run at the same time, or the screen is blurred.

Step 4: Check whether it is a problem with the memory module, but generally the memory that has been added cannot be started after booting, and some will pull out the memory module, wipe it well in the place of the gold finger, and give it a try! ~

Step 5: The most likely,And the most anticipated problem,That is, the driver problem,People who do computers pay attention to a word,That is, all software problems,It's not a problem,Get a driver software or something,Drive it,Or go to the official website ** driver,The driver is not necessarily the latest is the best,In addition, there are some differences between the drive mode of A card and N card, and there are dual graphics cards,I'll introduce it later。
