What is the cause of the video card failure

The cause of the video card failure is usually the following

Bad contact. This is due to improper contact with the AGP slot on the motherboard, the general plug in a video card or clean the golden finger part of the video card can eliminate the fault.

Driver failure. After entering the system, the video card appears abnormal, generally because the driver is not installed correctly or caused by the driver error, simply reinstall the driver to resolve the failure.

　　Video card failure

Overclocking failure. Sometimes using overclocking software to overclocking the graphics card and cause the video card to not work correctly, you need to use the Overclocking software shortcut keys to restore the default working state of the video card.

　　Graphics card is not working stably

Failure phenomenon: The purchase of new graphics card in the use of instability, often panic phenomenon.

Failure analysis and Processing: Graphics card technology continues to improve the new graphics card is constantly on the market, and the new graphics card power is also increasing, if the graphics card can not get a stable enough current, will also cause the graphics card work instability, resulting in a panic.

If there is a circuit on the motherboard that can independently provide the AGP bus power supply, try to connect the video card cable to the top. Some motherboards have an option to adjust the AGP voltage in the BIOS, and you can try to increase the voltage of the AGP appropriately to enhance the stability of the AGP video card.

　　Graphics card cooling caused by the flower screen

Failure phenomenon: A computer in the normal use of the process of flower screen phenomenon.

Fault analysis and processing: the phenomenon of flower screen is usually due to the problem of graphics card. Open the chassis, remove the video card, found that the video card heat sink is very hot, conjecture may be due to the high temperature card chip led to Kafa. A cooling fan is then added to the video card chip. After reboot, the flower screen is troubleshooting.
