How to repair the graphics card of mining screen

1. Flower screens are usually repaired at chip level, such as false soldering of video memory and false soldering of main chip, which need BGA, and ordinary users can't repair them. Some of them are blown by hot air gun, but the probability is very low, which requires very professional techniques and techniques, and there is a high possibility of recurrence after blowing.
a small part of flower screens are caused by insufficient power supply of video card, Check the power supply part, check the capacitance of the graphics card for leakage and bulge failure, check the field effect transistor for aging (short circuit is unlikely, broken or short graphics card is generally not bright). The capacitor and the field transistor are better welded, and a high-power soldering iron is better. In fact, ordinary users can repair the capacitor and the field transistor, Sometimes the 16 pin power management chip is broken and can be replaced with a hot air gun

2. I used the 1g graphics card well all the time. Suddenly one day I played the game and the screen crashed. After that, I tried to change the driver, swipe the BIOS, reload the system, and change the power supply, but I couldn't. after checking a lot of information, I found that a friend had baked it in the oven, dead horse was a live horse doctor, so I roasted it too, removed the radiator chip of the graphics card and turned down, Put it in a microwave oven with light wave function and set it to light wave mode. First, try it for 20 seconds. The temperature is not high, and it's still not high for 30 seconds. After one minute or two minutes, touch the video card. It's very hot, but it's not scorched. The tin on the component is brighter than before. Maybe the tin has been baked and melted. Let the video card cool naturally in the microwave oven. Install a radiator, plug it into the computer, and turn it on, Two short and one long, they were plugged in again, and the power on was on. Master Lu's test was normal, and the 3D game was also normal. The power on temperature was 45 degrees, and the 3D game was 60 degrees. The flower screen of the graphics card was solved. Maybe the temperature of playing the game was too high before, which caused the false soldering of one component. Putting it in the microwave oven and baking it was equivalent to welding all components again. The problem of false soldering was solved, It is proved that the problem of false soldering can be solved by this method. To sum up, first let the temperature of the graphics card rise graally, so as to avoid damage caused by too fast heating. After each time, touch the temperature of the graphics card by hand, and I feel very hot. The solder is brighter than before, which proves that the heat is up. However, the damage of the graphics screen caused by component damage must be invalid. Maybe I'm lucky, The microwave mode of microwave oven can't bake metal. It's dangerous, but the light wave mode can. I hope it can help some friends. Some friends who don't understand the principle and won't use the microwave oven are cautious. This method is for reference only. They are responsible for the adverse consequences.

3. If the driver and system have been checked
take them to the computer repair shop or after-sales department for inspection and maintenance

4. Hello! Is the machine cooling well! Poor heat dissipation of many machines can lead to many problems. Burning the motherboard and short circuit of the graphics card will lead to black screen, white screen, flash screen, flower screen, overheating and false soldering damage of the BGA packaging chip of the graphics card. Just add soldering or replace the graphics card through professional BGA packaging and welding equipment and technology. There is a problem with the hardware, please send it for repair
if you have any questions, please hi me
our service tenet: low cost, good service, fast efficiency and quality assurance.

5. One is that the heat dissipation of the graphics card is not hot. After working for a period of time, it will cause the display to suddenly black or splash. If you have this problem in the normal use of the computer, you might as well focus on checking the radiator of the graphics card to see if the cooling fan has stopped running and if the radiator is hot. If there are these two cases, you should focus on improving the cooling system of the graphics card
Second, the video memory is damaged. Video memory is an important part of the video card, especially the memory in the computer, which is responsible for the temporary access of data. When the video memory is damaged, the splash screen will appear when the system starts up, which shows that the characters are confused and cannot be distinguished. If there is a problem with the video memory, it is necessary to replace the video memory. Since replacing the video memory is a very high technology activity, it is recommended to send it for repair< The third reason is virus. Some virus attacks also appear splash screen, when the splash screen is not caused by hardware, so if you restart, you can also remove the fault, but the solution is to use anti-virus software to thoroughly kill the virus< Fourth, the speed of video memory is too low. When the speed of the video memory is too low to match the speed of the host, there will be a splash screen phenomenon. At this time, you can only replace the video card But at present, the speed of the graphics card is very high, and this problem will not appear in general)
fifthly, the display card conflicts with some applications. This situation is often manifested in the exit of some applications will appear splash screen, random keystrokes are no response, similar to the crash, generally restart the computer, the fault can be eliminated.

6.

The performance of the graphics card is unstable, and the mining will be affected after the performance is affected

1. unload the driver of the graphics card, and then go to the official website or NVIDIA official website to install the driver of the graphics card to use

2. if there is still a problem after replacing the driver, you can detect each graphics card alone, See whether each graphics card is the same problem

3. if it is the same problem, you can re install the system, install the motherboard driver, and then install the graphics card driver

4. if only a single graphics card has a problem, change the adapter line and card slot to see if there is a problem, if you have a problem, you can contact the seller or after-sales inspection

7. Most of the time, the splash screen is caused by the design defects of other aspects of the graphics card manufacturers. There are many splash screen cards in a certain model of an indivial brand

8. There are two reasons for the display screen
the first one is the splash screen caused by software, such as the driver problem. In this case, you can try to re install the official version driver of the graphics card to solve the problem
the second one is caused by hardware, and the common one is caused by the damage of GPU and flash memory. This kind of problem can be solved by hardware maintenance
repairs can certainly be done. You can consult the after-sales service and ask several repair shops to compare the prices and see if the repairs are cost-effective.

9. Boot press F8 to enter the safe mode is normal, if it is normal that is the driver of the graphics card, you can try to update the driver of the next graphics card. If not, the screen is broken. It is recommended to go to the service center for testing.

10. The solution of computer splash screen:
1. Poor heat dissipation of the chassis and the splash screen caused by the temperature rise of the graphics card
the solution is: check whether the fan is running normally, add lubricating oil to the fan, clean the st in the chassis, and solve the problem of heat dissipation before troubleshooting< (1) restart the computer, press the F8 key continuously, jump out of the Advanced Startup menu, select enter "safe mode" to log in to the system, then enter the display setting under windows, select 16 color status, click "application" button, and click "OK" button
(2) restart the computer. In the normal mode of windows, enter the device manager, delete the graphics card driver, and restart the computer
(3) if the graphics card is loose, the problem can be solved by unplugging the card and re inserting it after shutdown
(4) if the system is overheated, including the high temperature of CPU and graphics chip, the cooling fan can be installed in the corresponding position of the chassis, or the chassis can be placed in a well ventilated place.
