How to solve the black screen of Windows 7 Ultimate system due to graphics card failure

First, install the right graphics card driver

You have installed Windows 7 Ultimate system friends should know that the graphics card driver has a huge impact on the display performance of the whole machine, installed and The difference is not very large, but in our actual use, we also found that even if the driver is installed, the impact of the different versions of the driver on the graphics card is different.

Generally, the driver cards that come with the graphics card manufacturers can find the driver that suits them, and the compatibility of these drivers is also good, but with the passage of time, the errors in the old version of the driver and The omission will be revealed, and the chip manufacturer will update the driver according to different errors. However, we can't say that the new driver is the best, because the driver updates are often targeted. If the graphics card has some minor problems or problems, then you may want to try different versions of the driver first.

ps: If it is a novice friend who does not know how to install the graphics driver, it is recommended that you install the driver wizard, this software can automatically detect and install the latest driver, the latest driver is better.

Second, we must do a good job of cooling the graphics card

Now the development of technology, whether it is the graphics card process or core /memory frequency has been rapidly improved, and with the improvement of performance, The calorific value of the graphics card has also become more and more huge. Under normal circumstances, large 3D game programs require high performance of the graphics card, so that the graphics card emits a lot of heat after working for a long time at full load. At this time, the heat dissipation of the graphics card itself and the chassis is very important. If the heat dissipation is poor, the temperature inside the chassis and the temperature of the graphics card will be too high, which will cause the system to run unstable. This will easily lead to errors such as abnormal game screens. It can even cause the system to crash.

Therefore, in order to effectively improve the stability of the system operation, the heat dissipation of the graphics card can not be underestimated, especially the high-end graphics card itself has a high frequency of work and a large volume, and should enhance the air flow efficiency inside the chassis. For the graphics card's own cooling system is not good, we can do it yourself to enhance the heat.

Third, to ensure the stability of the graphics card power supply

For the current mainstream high-end graphics card, in order to ensure its normal operation, we can often see the 6pin power interface of the graphics card and PCI on the motherboard -E+12v power interface, the power of the graphics card is as great as its performance. When friends upgrade the configuration, whether the power supply is sufficient or not has become a top priority. A power supply with good load capacity and strong output power can ensure stable operation of the graphics card and even the entire system.
