Computer motherboard and video card not compatible

Reasons for incompatible computer motherboards and graphics cards:

What are the main features of the video card and motherboard incompatibility:

1, when the graphics card inserted into the motherboard, a short circuit phenomenon, not on the electricity card.

2, but the video card in the work of the occasional display does not show the situation, but occasionally back to normal. However, if you insert a different motherboard, the video card will not show the occasional display of the phenomenon, which also indicates that the video card and motherboard are not compatible.

3, there is the monitor and the host is normal, but occasionally there will be a flower screen fault, so consider whether the graphics card is not compatible with the motherboard.

4, the last is the graphics driver led to the computer often crashes, updated graphics driver or can not solve the problem. It is said that the video card itself is defective and the motherboard is incompatible with computer failure.

So if your computer shows up, your motherboard and graphics card are in an incompatible state. If the software aspect is the graphics driver and the motherboard is not compatible, then can update the video card drive method to solve the problem. Right-click Computer, select the Device Manager option, let the "Connection adapter" right click on it, select "Update Driver Software", and select "Automatically search for updated driver software", and so on, and so on, when the system detects the graphics driver, and then install it. As shown in the figure:

Of course, if the motherboard and graphics hardware is incompatible, then you must replace the graphics hardware. Trying to switch to a different brand of video card will solve the problem of incompatible video card and motherboard.

Computer keyboards-Graphics cards-incompatible solutions for hard disks and motherboards

Main fault performance:

(1) Irregular inspection of the keyboard or mouse;

(2) The keyboard or mouse is lost in the course of use;

(3) There is the mouse in the use of the process without arrows indicated, but can be normal operation or arrows lost;

(4) Sometimes there will be dragging the mouse when the plot with the mouse arrow movement.

(5) After the machine sleep, wake up with the machine, the mouse can not be used, only restart the computer or the mouse to pull down and plug it up.

This situation is not generally the problem of the motherboard, as long as the replacement of a qualified keyboard and mouse on it.

3. The graphics card is not compatible with the motherboard

Failure performance:

First, the graphics card production process is not standardized, resulting in the insertion of an AGP slot, there is a short-circuit situation, when the performance is not on the power.

Second, the graphics card work is sometimes normal, can light the display, and sometimes irregular point does not light the display. But it is perfectly normal to use the graphics card on a different motherboard. Only the video card can be replaced for this situation. Third, the computer host is also working properly, the display of the image is normal, but it is accidental irregular appearance of the picture screen. Four is the use of this graphics card, the system will work unstable, or frequent crashes, or often off the graphics driver. For this situation may also be due to the graphics card driver design defects, resulting in graphics card work instability, resulting in the system panic.

4. Hard drive is not compatible with motherboard

This is not much, but there are some hard drives on this motherboard to recognize the good, but in another motherboard but still do not recognize. For example, the original one hundred or two hundred trillion small hard drive, if you want to boot from the hard disk, you must be in the IDE1 interface of the main disk position, in order to start normally, otherwise inserted can be read can write, but is not able to start. For hard disk speed problems, generally not a compatibility issue, but the setting or wiring error. such as: The DMA66 line back, the hard drive properties of the DMA function is not opened; The IDE channel in CMOS settings is not set to automatic, but is artificially set to PIO4 the following transmission mode, the hard drive cable is too long, resulting in data attenuation is too large, transmission rate drops, the hard disk's power interface problem or power shortage of switching power supply, resulting in hard drive voltage instability and low. The solution to this kind of problem is to forestall a little and carefully check the related settings of the hard disk. Especially when the DMA66 line is reversed, the data transfer rate will fall by half. In addition, use the nearest interface as much as possible when using a data line.
