What should I do if the Win7 computer shuts down automatically? Computer crash reason summary

About the computer automatic shutdown is a matter of how many computer users have encountered, I have a few friends have asked me such a problem, for some players who like to play 3D games Say, if you play 3D games, frequent crashes are a very painful thing, huh, here I summarize the rare causes of this type of failure.

First, the graphics card itself.

1 Memory corruption. If the graphics card's memory is damaged, it is very easy to happen. Even if you don't crash, you will frequently report the 3D game after a period of time. If this happens, it is better to use the replacement method to change the block to try it. 2 The line or chip of the graphics card itself is damaged, causing a malfunction, which is also solved by the replacement method.

Second, the AGP slot voltage is insufficient. The reason is that the voltage is unstable, which may cause the AGP slot to be insufficiently powered and cause a crash when playing 3D games. Therefore, you should check whether your power supply is sufficient or the power supply line is stable, or you can try to increase it in the BIOS. AGP voltage is generally increased by 0.1V, but it cannot be adjusted too high, otherwise it will be very dangerous.

Three, graphics card work materials and compatibility issues. Some of the brand-name or small- and medium-sized graphics cards work when the lack of materials will make the electrical compatibility of the graphics card greatly reduced, which means that when the 8X graphics card runs at 8X, it will cause 3D games to crash frequently, and when the AGP is adjusted in the bio After 4X, there is no problem. This is because 8X has high requirements on the electrical compatibility of the graphics card. If the material is not working well, it is very easy to have problems.

Four, heat dissipation. Check if the CPU temperature is normal in the BIOS, and then check if the heat dissipation of the graphics card is abnormal.

V. System software problems.

1 Check if your motherboard patch and graphics card driver are correct, if the graphics card driver is damaged, if there is a crash, try changing a motherboard patch or graphics card driver. Note that the latest is the best try. Hit the driver or patch on the CD that came with your hardware. 2 Look at the directx file is damaged or the version is too low, run the DXDIA G command to run the directx diagnostic sequence. 3 See if hardware acceleration is turned on. 4 Clean up the system's junk files. If it doesn't work, try to reinstall the system.

Six, if it is an integrated graphics card, you should also check the memory, because the memory used by the integrated graphics card is a part of the memory to the integrated graphics chip, the rare causes and solutions are the above, when After the failure, the software will be tested step by step according to the principle of soft and hard. I believe you will find out the reason.

The above points should solve the problem of how the computer automatically shuts down. If it can't be solved, then hold the computer to the computer maintenance staff to see it. Only professional maintenance personnel can solve it easily. These failures.
