Due to the convenient assembly and easy expansion of the PC, it has accelerated the popularity of the computer to a certain extent, and computer accessories manufacturers have also made great contributions to this. However, it is precisely because we use the computer (especially compatible machine) is combined by the products produced by different manufacturers, and they are inevitably happening to "friction". This is what we usually say, the term "compatible machine" is also derived here. Next, I will talk about what kind of incompatibility between the bottom components, and how we solve this problem. 1. Memory and motherboard are not compatible with memory and motherboards are more common, and it is often used as yesterday's computer, but this morning, this is called "嘀". Only open the chassis and take the memory strip to re-insert it. Note: Be sure to unplug the host and power cord when plugging the memory module to prevent accidental burning memory. This is a light, serious, you need to wipe a few memory slots several times to light the machine. However, if you don't have ten or a half months, the alarm will then appear again. 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 not a matter of continuous running ten and a half months. Otteen is always alarm this no one can not stand it. This situation is that typical memory is not compatible with the motherboard. The causes of this failure are: (1) The memory strip is not standardized, and the memory strip is a bit thin. When the memory is inserted into the memory slot, there is a certain gap. If there is vibration or dust falling during use, there will be poor memory contact, and an alarm is generated. (2) The gold finger process of the memory strip is poor, and the surface gold plating of the gold fingers is poor. During long-term use, the oxidation layer of the gold finger is gradually thicker, and after accumulating to a certain degree, the memory is poor, and the memory alarm is in the boot. (3) The quality of the memory slot is poor, the reeds and memory sticks are not in real, and there is always a hidden danger during use, and it will not be bright at a certain amount of time, boot alarm. ⑷ is a pure incompatibility: a strike, it is used in some motherboards, but it is often crafted on this motherboard, or cannot start normally. This is a typical incompatible situation. Treatment scheme: (1) Wipe the gold finger of the memory strip with the rubber and re-insert the slot. (2) Fill in the sides of the memory slot by hot melt glue to prevent oxidation during use. (3) If you use it for a while, a alarm will appear. At this time, you can replace the memory module first, see if there is still alarm during the future use. ⑷ If there is a memory alarm after a while, there is only a replacement motherboard to completely solve the problem. For memory strips and motherboards that can only replace the memory strips of other brands due to technical issues, of course, the motherboard can be changed. For example: Kingmax's memory is incompatible with the motherboard of Panying, as long as the two goes to one, there will be blue screen. 2. The keyboard is not compatible with the motherboard and the motherboard is not compatible with the motherboard. It is mainly the quality of the keyboard and the mouse. The data sampling speed of the chip is inconsistent with the main board, and the keyboard error will occur in the process of use. Main fault performance: (1) No keyboard or mouse; (2) Lost during use; (3) There is no arrow instruction during use, but it is possible to lose it normally or arrow; There is a drag mouse when there is a piece of mouse with the mouse arrow. After the machine is sleeping, after waking up with the machine, the mouse cannot be used, can only restart the computer or pull the mouse to plug it. This situation is generally not the problem of the motherboard, as long as the qualified keyboard and the mouse are.
3. The graphics card and motherboard are incompatible with the fault: First, the graphics card production process is not standardized, resulting in a short-circuit situation after inserting the AGP slot, and the performance is inconsistent. Second, the graphics card is sometimes normal, it is possible to illuminate the display; sometimes no regular point is not bright. But using the graphics card in other motherboards is completely normal. 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 will accidentally irregular image screen. 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 operate unstable, causing the system to crash. 4. The hard disk is not compatible with the motherboard, but also, some hard drives are well recognized on this motherboard, but they don't recognize it in another motherboard. For example, the original one and two hundred trillion hard disks, if you want to start from the hard drive, you must start properly in the primary disk location of the IDE1 interface, otherwise you can read it after you can read, but you can't start. For problems with slow hard disk, it is generally not compatible, but is set or wired. Such as: Turn the line of the DMA66; the DMA function in the hard disk attribute is not open; the IDE channel in the CMOS setting is not set to automatic, but the manual setting is a transmission mode below PIO4; the hard disk line is too long, resulting in data attenuation Excessive, the transfer rate is lowered; the power interface of the hard disk is problematic or the switching power supply is insufficient, which causes the power supply voltage of the hard disk to be unstable and low. The solution to this type is that the heart is fine and carefully checks the relevant settings of the hard disk. In particular, when the line of DMA66 is connected, the data transfer rate will drop half. Also use the nearest interface when using the data cable. 5. Sound card and motherboard is not compatible with this situation is mainly the system's equipment, causing the interrupt or address of the sound card or the conflict with other equipment, or the system crashes, or the system is started, or the system is unstable, or the sound card is installed. The modem is not. This situation is solved after the system is installed, enters the resource manager, open the properties of the corresponding device, manually modify the address or interrupt number of its conflict, so that it can take up idle. Maybe this will restart the computer multiple times to complete. One point, the same interrupt number, the input device, and the output device can share one. Now there is 16 interrupt numbers from the PC, from 0-15, but only more than 10, because timers, real-time clocks, keyboards, etc., can be fixed, and there is no IRQ number. However, because the sound card is not working, after inserting the sound card into the PCI slot, I causing the motherboard to add electricity. I have encountered it. At first, I thought that the sound card was bad. Who knows a piece of model, or the same failure, but this sound card is inserted on the other model. Finally, the sound card that can only replace other models will be solved. 6. NIC and motherboard is not compatible with the network card except the address and interrupt conflict, there is still a case where the speed is slow, the Internet and the download are particularly slow, and even the unbearable point. This situation is also due to conflicts, the cause may be because of the reasons of the network card, thereby causing electromagnetic interference with a part of the chassis, affecting the data transmission speed of the network. For the former case, the processing method is the same as the sound card; for the latter case, it is best to replace different brands of NIC for testing.
7. The latest BIOS is not compatible with the motherboard. Generally, when our motherboard does not know new CPUs and other new components or when there is no capacity hard drive, or when the motherboard has some small bugs, we can download the latest on the board online. BIOS program, you can refresh it. However, I have encountered an example of the Jin Changcheng brand. The configuration is C433. It used to use a 4.3G hard disk, and then she wants to hang a 40G large-capacity hard drive, but the original P6Set-Me motherboard is not recognized. Later, I found it online. The latest version 1.2 BIOS can recognize the 65G hard drive, download it from the Internet, and refresh it. 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 not be discovered when the sound card is installed. Just click on the mouse and the speaker will continue to pass the "Dudu" sound, and cannot be removed. At first, I thought it was a problem with the system without installing or the sound card driver, but I have never solved the problem. It is best to find that when comparing the two BIOS code contents, the second is except that the system code is different, and the capacity of the ACPI module is slightly different, so the ACPI in the old BIOS is stripped out, then add it to the new BIOS, then Refresh the BIOS chip and then start the system, discover the fault resolution. This is a typical BIOS code and a problem of motherboard conflict. 8. The monitor is not compatible with the motherboard for Samsung, LG display, has a signal level setting in its OSD menu, which can accept the display signal level in both 0.7V and 1.0V. The signal level of the graphics output of the PC us generally used is 0.7V analog signal. If the signal level of the display is misused to 1.0V, the entire image of the display is biased and biased. Especially for the display used by the professional map, it is high for color temperature requirements, as this is related to the actual output effect, so when selecting a display, be sure to use high-end displays, and check whether the display input signal and the output signal of the display input signal match . 9. The printer is not compatible with the motherboard. This is generally not easy. It is mainly due to the print signal level of the motherboard and the printer's interface circuit that does not match, causing an error in printing, which may be that the print data line is unqualified or The data line is too long, resulting in an attenuation during the transmission process. I am in the maintenance process, because the parallel data line causing a failure of printing, especially if the length of the data cable is preferably not more than 2 meters, otherwise some strange faults can be caused, the print speed is very slow, Print half-page, print garbled, etc. Example: One customer purchased SUSTC motherboard, PII450CPU compatible machine and OKI8340C printer, because customers are not satisfied with the printer's printing effect, think that the precision of printing is not high and the print straight line is not straight, to replace the Star3200 printer. But after replacing the printer, you can only print 5 lines, then you can't print, you cannot print it. I also suspect that the data line has a problem, but the fault is still after replacing. However, when using OKI8340c, it is still normal. Note: OKI8340C and STAR3200 printers are compatible with LQ1600K print drivers, and do not need to replace the driver when replacing the printer. 10. CD-ROM and motherboard are not compatible with this situation as when the optical drive is inserted, the computer host startup process slows slow, easy to crash, blue screen, etc., but as long as the optical drive is all normal. This is generally damaged by the circuit of the optical drive, causing a pause or waiting time when data transmission is too long and dead.
The method of solving is to minimize the system, then plus other parts as the same, when adding to a part, then this is the problem. In principle, it cannot be classified as incompatible failures in principle, but there is a lot of chances, and it is listed here for your reference. 11. The main board and chassis are not compatible. This is actually not compatible. It is mainly the process of production, irregularity, causing the motherboard to make the motherboard to touch the main board and the cabinet, or various expansion cards Other faults appear in contact with the motherboard. I have encountered it once, just put the board and other components in the chassis, I often have crash and can't start, and only the chassis can be started, just start the chassis, I can't start at all. However, it is possible to turn on the motherboard to boot for a long time and run stable. 12. The power supply and motherboard is not compatible with power as a power source of the computer, but the key to the key. However, many friends always spend the big Money in CPU and memory, but there is also province in the power supply. When it comes to the serious illness, strike, I know that it is a power source, I bought a good power. Why isn't you in place? Computer components have high stability requirements, 12V, 5V changes within 10%, 3.3V changes within 5%. If the output voltage of the power supply exceeds this range, some parts will be strangely fault, some simply strike, some may be completely scrapped. 13. Mobile devices are not compatible with USB interfaces. In fact, this type of failure cannot be classified as incompatible. Most are too large, and the power supply current of the USB interface is limited, causing mobile devices that cannot be used normally. If a mobile hard disk, the USB interface scanner or other mobile device does not use it normally, pay attention to check if the device's working status indicator is normal, check if the driver is installed correctly, and finally check if the power supply of the motherboard USB interface is Jumper control. The power supply of the motherboard USB interface is preferably powered by main power supply 5V. Sometimes there will be the same mobile hard disk can be used on some hosts, but can't be used on some hosts. After the reasons for exclusion, it may be because different motherboard USB is different, and some are direct power supply. No components are added between the 5V power interface to the USB interface; some are the use of triode controllable power supply, which can provide complete protection measures, but the supply current is limited to 500 mA. 14. The headset is not compatible with the sound card or the motherboard. After plugging in the earphones, the sound of the earphones is particularly small, there is no way to use normally, this has two situations: (1) Headphones's impedance of our normal use headphones are 8OHM impedance earpies, if We buy a high-resistance earphone or other special-purpose headphones. At this time, it will feel that the sound is particularly small, even if you adjust the sound to the biggest, there is no improvement. This is because the load input impedance is caused by the output impedance of the device. (2) Whether there is a function on the motherboard, there is no power on the motherboard, and only the signal to provide a source of active speakers belled. If you use a headset, you will feel very small in your headphones, there is no other way to work with active devices. 14. Wap-drive with the chassis is not compatible with the floppy drive, this situation we often encounter, one is too high, the second is that the floppy drive is also sick. Special floppy drive, although it has already reached the end, it is still useful, a network card driver, solve the hard disk logic lock, make an encrypted disk, and some anti-virus software also like to use floppy disks.
