-------------------------------------------- ------------------ black failure black failure



computer hardware failure caused by a computer hardware failure can be divided into the following two categories: black

1,

mains failure or damage host power quality black failure

a, host host computer power due to failure caused due to poor Faults are common. For example, when some new devices are added, the display has a black screen failure, and the quality of the power supply is eliminated after the hardware quality and compatibility problems are eliminated. The lack of power is the main cause of the failure, replacing the high-powered high-quality power supply or using the voltage regulator. Power is the best way to resolve this type of failure.

B, malfunction, damage or

PCs mass assembly caused by the quality, is the main cause of failure causes the display black. Problems such as memory, display card, motherboard, CPU, etc. may definitely cause black screen failure. The fault is that the display light is orange. At this time, the replacement card can be replaced by the replacement method, and the memory, CPU, motherboard and other components are tried. This is the easiest and quickest solution.

C, the quality of the connection between the parts

memory, display card or the like between the motherboard and plug loosening or incorrect, resulting in poor contact dust and the like is the main cause of the black screen failure. Moreover, there is a problem with the connection between the display card and the display, or the data line of the drive is reversed, which may cause a black screen failure.

D, black failure caused by excessive

OC or OC not suitable to overclock overclocking member not only causes a failure to produce black, can also cause severe damage to the parts. If excessive overclocking or overheating of components that are not suitable for overclocking or poor heat dissipation during normal use due to fan damage, the system will not protect the CPU from blackout.
