1. Memory is not compatible with the motherboard
Memory is more common with the failure of the motherboard, and the performance is still good for the computer yesterday, but he opened this morning.
That is, "嘀" is called a non-stop. Only open the chassis and take the memory strip to re-insert it. Note: Inserting
When the memory bar must unplug the host and power cord to prevent accidental burning memory. This is a fault, serious, need to put a few
The memory slot is wiped several times to light the machine. But I can't use it for ten and a half months, I will still have alarm again.
condition. As long as you turn on the chassis, you will be inserted. You said that there is a problem with the machine, as long as you light up, it is a continuous run.
There are no problems in the day and months. Otteen is always alarm this no one can not stand it. This is the typical memory and the motherboard.
Rong.
The cause of this failure is:
(1) The memory strip is irregular, and the memory strip is a bit thin. When the memory is inserted into the memory slot, there is a certain gap. If
If there is vibration or dust in the process, it will cause memory contact and alarm.
(2) The gold finger process of the memory strip is poor, and the surface gold plating of the gold fingers is poor. During the long time of use, the golden hand finger table
The oxide layer of the surface is gradually thickening, and after a certain degree, it will cause memory contact, and the memory alarm is turned on.
(3) The memory slot is poor, the reed and the memory of the memory strip are not in touch, and there is always a hidden during use.
In patients, it will not be bright at a certain amount of time, boot the alarm.
⑷ is a pure incompatible situation: a strike, it is used in the motherboard, but it is on this motherboard.
But often crash, or you can't start normally. This is a typical incompatible situation.
Treatment scheme:
(1) Wipe the golden finger of the memory strip with eraser and reinsert the slot.
(2) Fill in the sides of the memory slot by hot melt glue to prevent oxidation during use.
(3) If it is used for a while, there is still a alarm. You can replace the memory module first, see it in the future.
Whether there is a alarm in the process.
⑷ If there is a memory alarm after a while, there is only a replacement motherboard to completely solve the problem.
For memory bars and motherboards, only the technical problems are not compatible, can only replace other brands of memory, of course
Change the motherboard. For example: Kingmax's memory is incompatible with the motherboard of Panying, as long as the two goes to a piece, there will be blue screen conditions.
.
2. Keyboard is not compatible with the motherboard
The problem with the keyboard and motherboard is mainly the keyboard and the mouse is not good, and the data sampling speed of the chip is in the motherboard.
The reception is inconsistent, and the keyboard error will occur during the use process.
Main fault performance:
(1) Unspecically, the keyboard or mouse cannot be inspected;
(2) The keyboard or mouse is lost during use;
(3) Another is that the mouse does not have an arrow instruction during use, but it can be lost in normal operation or arrow;
⑷ Sometimes there is a drag mouse to move with the mouse arrow.
After the machine is sleeping, after waking up, the mouse cannot be used, can only restart the computer or put the mouse down again
Plug.
This situation is generally not the problem of the motherboard, as long as the qualified keyboard and the mouse are.
3. The graphics card is not compatible with the motherboard
Trouble performance:
First, the graphics card production process is not standardized, causing a short circuit to appear after inserting an AGP slot, and it is not able to add electricity.
.
Second, the graphics card is sometimes normal, it is possible to illuminate the display; sometimes no regular point is not bright. But insert the graphics card
It is completely normal on other motherboards. Only the graphics can be replaced with this situation.
Third, the computer host is also working properly, and the image display of the display is also normal, but it is an accidentally irregular image flower.
Screen condition.
Fourth, as long as this graphics card is used, the system will work unstable or crash, or often drop the graphics card. This is also possible because there is a defect in the design of the graphics card driver, causing the graphics card to work unstable, causing the system to die
machine.
4. The hard disk is not compatible with the motherboard
This situation is not much, but there are also hard drives to recognize it on this motherboard, but in another motherboard is also dead.
deny. For example, the original one and two hundred trillions of small hard disks, if you want to start from the hard drive, you must be in the primary disk location of the IDE1 interface.
Start normally, otherwise you can read it after plugging, but you can't start.
For problems with slow hard disk, it is generally not compatible, but is set or wired. Such as: put the line of DMA66
Reverse; the DMA function in the hard disk property is not open; the IDE channel in the CMOS setting is not set to automatic, but the artificial settings.
Placed the way to transfer below PiO4; the hard drive line is too long, resulting in too large data attenuation, decrease in transmission rate; the power interface of the hard disk is
Problem or switching power supply is insufficient, resulting in unstable and low power supply voltage. The solution to this type of problem is the fine one
Click, take a closer check of the related settings of the hard drive. In particular, when the line of DMA66 is connected, the data transfer rate will drop half. In addition to
When using the data cable, use the nearest interface as much as possible.
5. Sound card is not compatible with the motherboard
This situation is mainly the system's equipment, causing the interrupt or address of the sound card and conflicts with other equipment, or the system is dead.
Or I can't start normally, or the system is unstable, or the sound card is installed, but the modem is not. This
Solution Solution After the system is installed, enter the resource manager, open the properties of the corresponding device, manually modify its conflict
Address or interrupt number, it is possible to occupy it. Maybe this will restart the computer multiple times to complete. Need to explain
One point, the same interrupt number, the input device and the output device can share one. Now there is 16 interrupt numbers in the PC, from 0
-15, but only more than 10, because timers, real-time clocks, keyboards, etc. should be fixed, can be fixed, energy-separated IRQ
There is no one.
However, because the sound card is not working, after inserting the sound card into the PCI slot, it has caused the motherboard to add electricity.
I met a time. At first, I thought that the sound card was bad. Who knows a piece of model, or the same fault, but this
The block card is inserted on the motherboard of other models. Finally, can only replace other types of sound cards to solve this problem
.
6. NIC is not compatible with the motherboard
In addition to the address and interrupt conflict, there is another situation that is slow, the Internet and the download are very slow, even
Unbearable point. This situation is also due to conflicts, why because of the reasons for network card work, and
A component in the box causes electromagnetic interference, affecting the data transmission speed of the network. For the former case, processing method
Sound card; for the latter case, it is best to replace different brands of network card for testing.
7. The latest BIOS is not compatible with the motherboard
Generally, when our motherboard does not know new CPUs and other new parts, or if there is no capacity hard drive, or have a motherboard has one
When some small bugs, we can download the latest BIOS program on the board and you can refresh it. But I have encountered it.
One example is the Jin Changcheng brand machine. The configuration is C433. It used to use 4.3G hard drive, and later I want to hang a 40G big capacity hard.
The disc, but the original P6Set-ME motherboard is not recognized. Later, I found it online, the latest version 1.2 version of BIOS can recognize 65g
Big hard drive, download it from the Internet, then refresh. Everything is very smooth, the startup is normal, the hard disk is also recognized, and this is thought to solve this. However, after the system is installed, it will be found when the sound card is installed. As long as you click on the mouse, you will not stop in the speaker. "
Dudu "sound, unable to remove. At first, I thought it was a problem with the system without installing or the sound card, but I have never
Solve the problem. It is best to find that the second bios code is found in the comparison, and the second is in addition to the system code part. ACPI model
The capacity of the block is also slightly different, so put it out of the old BIOS, add it to the new BIOS, then refresh the Bio
S chip, when the system is started, the fault resolution is found. This is a typical BIOS code and a problem of motherboard conflict.
8. The monitor is not compatible with the motherboard
For Samsung, LG displays, there is a signal level setting in its OSD menu, you can accept the display signal level.
This is the first to be in both 0.7V and 1.0V. The signal level of the graphics output of the PC us used is 0.7V analog signal,
If the receiving signal level of the display is ignored to 1.0V, the entire image of the display is biased and biased. Particularly
Professionally made the display used, high color temperature requirements, because this is related to the actual output effect, so the display is selected
When you should use a high-end display, and check whether the display input signal is matched to the output signal of the graphics card.
9. The printer is not compatible with the motherboard
This situation is generally not easy to appear, mainly because the printed signal level output from the motherboard does not match the interface circuit of the printer.
There is an error in printing, in which there is also a possibility that the print data line is unqualified or the data line is too long, resulting in signals in transmission.
The attenuation during the process is too large. I am in the maintenance process, because the parallel data line causing a failure of printing, it has encountered many times,
Don't be more than 2 meters of the data line, otherwise some strange faults can be caused, the print speed is very slow.
Print half-page, print garbled, etc.
