Caused by graphics card fault causes and solutions

Comments: The graphics card failure caused by reasons and solutions
The cause is usually caused by graphics card failures are the following:
Poor contact. Poor contact due to the AGP slot on the graphics card and motherboard, general swappable graphics card or clean the card cheat site troubleshooting.
Driver failure. Into the system graphics display is not normal, generally, just re-install the drivers you can troubleshoot the driver is not installed correctly or driver error caused.
Graphics fault monitor maintenance
Overclocking failure. Sometimes the use of overclocking software graphics card overclocking the graphics card does not work, then need to use overclocking software shortcuts revert to the default graphics card working state.
Graphics component failure. Due to the failure of the components of the graphics card itself, only to be replaced or contact a professional maintenance staff for repair.
The following describes the common graphics troubleshooting instance.
1) graphics job insecurity
Fault phenomenon: the purchase of new graphics cards in the use of unstable, and often crash phenomenon.
Failure analysis and processing: graphics technology continues to progress makes new graphics listed, the new graphics card's power consumption is also increasing, if the graphics work can not be stable and sufficient current will cause the instability of graphics, resulting in crashes .
If the motherboard can be independent of the AGP bus power supply circuit, as far as possible to the graphics of the wires to the above. Some motherboards have the option to adjust the AGP voltage in the BIOS, you can try to appropriate to enhance the AGP voltage to enhance the stability of the AGP graphics card.
2) video card cooling caused by bad Huaping
Fault phenomenon: a computer in the course of normal use Huaping phenomenon.
Failure analysis and processing: Huaping phenomenon is due to graphics issues. Open the chassis, remove the graphics card, graphics card heat sink is very hot, the conjecture is likely to lead to graphics Huaping graphics chip temperature is too high. Then add a cooling fan for the graphics chip. Reboot after Huaping troubleshooting.
