Computer memory is the stomach of a computer. If there is a problem, we have to know how to operate it, otherwise we will let others help you and waste the money of white flowers. Part of the memory problem is due to the reason for upgrading the memory, but due to the mismatch of memory types, there are often some troubles. The specific memory problems and the tricks are as follows. Steps/methods 1, unable to start the power normally: There are three ways to solve this kind of phenomenon: First, replace the memory location, this is the simplest and most commonly used method, generally the low-speed old memory Insert it in the front position. Second, under the premise of basically booting, enter the BIOS settings, and set the memory-related settings according to the specifications of the low-speed memory. For example: use one of the memory (if it is [url="]DDR[/url]333 and DDR400 memory mix, it is best to use DDR333 memory), start the computer, enter the BIOS settings, the memory work The frequency and response time are slowed down, and the old memory can be stably operated, so that the second memory can be turned off. 2, the computer runs unstable tricks: the emergence of such problems is mainly caused by memory compatibility, the basic idea of solving is basically the same as above. First, replace the location of the memory. Second, in the BIOS, the option to turn off the memory automatically configured by SPD is changed to manual configuration. Third, if the motherboard has an I/O voltage adjustment function, the voltage can be appropriately increased to enhance the stability of the memory. 3, after the mixed insertion memory capacity identification is not correct: the cause of this phenomenon, the first may be caused by the motherboard chipset itself, some old motherboards only support 256MB of memory capacity (i815 series only supports 512MB ), the excess is not recognized and used. Of course, there are some cases where the motherboard cannot support high-level memory particles. The only way to solve such problems is to replace the motherboard or memory. In addition, in some cases, this problem can be solved by adjusting the order in which the memory is inserted. The problem of unstable memory mixing is an old problem. Faced with this situation, I suggest that you choose high-quality memory like Kingston and Jintek when purchasing memory modules, because their electrical compatibility and stability are excellent, the probability of problems is lower, and There are also guarantees after sale. The other part is because the memory is in use, the contact between the gold finger and the motherboard slot is caused by the problem caused by the virus or the like. The specific memory problems and the tricks are as follows. 4. The computer can't start normally. After the power of the computer is turned on, the chassis alarm horn will beep for a long time, or the computer can be started after the power is turned on but the operating system cannot be entered normally. The screen appears "Error: Unable to ControlA20 Line" After the error message and crashed. Weapons: Most of the above failures are caused by poor contact of the memory in the motherboard. The method is to open the chassis, pull out the memory, wipe the gold finger and memory slot of the memory with alcohol and a clean paper towel, and check the memory slot for signs of damage. Re-insert the memory after the wipe test is finished. In the case of the problem can be solved, if it still can not boot, the memory is pulled out and inserted into another memory slot to test, if the problem still exists, the memory is damaged, and only a new memory module can be replaced at this time. 5. After booting, the following message is displayed: “ON BOARD PARLTY ERROR”. Weapons: There are three possible reasons for this phenomenon. First, the parity check in CMOS is set to be valid, and there is no parity check bit on the memory stick. Second, the parity check circuit on the motherboard is faulty. Third, the memory module is damaged or has poor contact. The processing method, first check the relevant items in the CMOS, and then re-plug the memory stick to try, if the fault still can not disappear, then the parity check circuit on the motherboard is faulty, change the motherboard. 6, the Windows system running DOS state of the application software (such as DOS running game software, etc.) when there is a black screen, flower screen, crash phenomenon. Weapons: The general situation of this kind of fault is caused by software distribution and memory conflict. Generally, it is black screen, flower screen, and crash. The best way to solve this problem is to exit the windows operating system and run these in pure DOS state. program. 7, Windows running speed is significantly slower, the system has many tips about memory errors. Weapons: This type of failure is generally caused by an application running under Windows illegally accessing memory, too many unnecessary plug-ins in memory, applications, too many active windows open, and application-related configuration files are unreasonable. The reason can make the speed of the system slower, and even more serious, even crashes. This kind of fault must be solved by removing some illegal plug-ins (such as 3721), memory resident programs, reducing active windows and adjusting configuration files (INI). If the speed is obviously slow when running a certain program, then you can pass the heavy Install the application's method to solve the problem, if the system slows down when running any application software or program, then the best way is to reinstall the operating system. 8. The memory is stored in the memory after being infected by the virus program. The size of the memory value in the CMOS parameter is modified by the virus, causing the memory value to be inconsistent with the actual memory size of the memory module. When used, the speed is slow, the system crashes, and the like. Weapons: First use the latest anti-virus software to carry out comprehensive anti-virus treatment on the system, thoroughly clean up the virus in the system. Since CMOS has been infected by a virus, it can be restored to its default value by discharging the CMOS. The method is to short-circuit the CMOS short-circuit, restart the machine, carefully check the hardware parameters after entering the CMOS, and correctly set the parameter values of the memory. 9. The computer is upgraded for memory expansion, and a memory module that is incompatible with the motherboard is selected. Tips: Before upgrading the memory module of the computer, you must carefully check the main instructions of the motherboard. If the motherboard does not support large-capacity memory above 512M, it will not work properly even after the upgrade. If the motherboard supports, but due to the poor compatibility of the motherboard, you can upgrade the BIOS of the motherboard to see if it can solve the compatibility problem.
