Solutions to nine common problems with computer memory
1. Failed to boot normally
Solution: there are three main ways to solve this problem: first, change the memory location, which is the simplest and most commonly used method, generally, the old low-speed memory is inserted in the front position. Second, when the system is able to boot, enter the BIOS settings and set the memory-related settings according to the low-speed memory specification. For example, use one of the memory (if it is a combination of [url = "] DDR [/url] 333 and ddr400 memory, it is best to use ddr333 memory) to start the computer, go to BIOS settings, and slow down the memory operation frequency and response time. The old memory can run stably before shutting down and inserting the second memory.
2. Unstable computer operation
Solution: Memory compatibility is the main cause of such problems. The basic solution is roughly the same as above. First, change the memory location. Second, disable the option of automatic memory configuration from Spd in bios and change it to manual configuration. Third, if the motherboard has an I/O voltage adjustment function, you can increase the voltage appropriately to enhance the memory stability.
3. incorrect memory capacity identification after hybrid insertion
Solution: the first reason may be the reason for the Motherboard chipset itself. Some old motherboards only support 512 MB of memory (i815 series only support MB ), the excess parts cannot be identified or used. Of course, there are still some situations because the motherboard cannot support high memory particles. The only way to solve this problem is to replace the motherboard or memory. In addition, in some cases, this problem can be solved by adjusting the memory insertion sequence.
The problem of unstable memory plug-in is an old problem. In the face of this situation, I suggest you choose high-quality memory such as Kingston and kingtek when purchasing memory, because they have excellent electrical compatibility and stability, the probability of a problem is lower, and after-sales services are also guaranteed.
The other part is caused by problems such as poor contact between the golden finger and the motherboard slot during use or virus. The memory problems and measures are as follows.
4. The computer cannot be started normally. After the power of the Computer Host is turned on, the alarm horn of the chassis appears for a long time, or after the host is powered on, the computer can be started but cannot enter the operating system normally, the error message "error: Unable to controla20 line" is displayed on the screen, and then the system crashes.
Solution: most of the above faults are caused by poor contact of the slots with memory on the motherboard. The solution is to open the chassis and pull out the memory, wipe the golden finger and memory slot with alcohol and clean paper towels, and check whether the memory slots are damaged, after the health check is completed, the memory will be re-inserted. Generally, the problem can be solved. If it still cannot be started, the memory will be pulled out and inserted into another memory slot for testing. If the problem persists at this time, it indicates that the memory is damaged. At this time, you can only replace the new memory.
5. The following message is displayed: "On board parlty error ".
Solution: There are three possible reasons for such a phenomenon. First, the parity check in CMOS is set to valid, and there is no parity check on the memory. Second, the parity circuit on the motherboard is faulty. Third, the memory is damaged, or the contact is poor. Solution: first check the relevant items in CMOS, and then re-insert the memory to try. If the fault still cannot disappear, the parity circuit on the motherboard is faulty.
6. Black screens, flags, and crashes occur when applications (such as game software running under DOS) in windows are running.
Solution: in general, this fault is caused by conflicts between software allocation and memory usage. It usually appears as a black screen, a screen, or a crash. The best solution is to exit the Windows operating system, run these programs in pure DOS state.
7. Windows runs slowly, and the system prompts many memory errors.
Solution: this type of fault occurs generally because the applications running in windows have illegal access to the memory, too many unnecessary plug-ins in the memory, too many open applications and activity windows, and application-related configuration files. unreasonable or other reasons can make the system slow down, even worse, there may be crashes. To solve such a fault, you must clear some illegal plug-ins (such as 3721), memory resident programs, reduce the activity window, and adjust the configuration file (INI, if the speed slows down when running a program, you can reinstall the application. If the system slows down when running any application or program, the best way is to reinstall the operating system.
8. The memory will reside in the memory after the virus program is infected, and the memory value in the CMOS parameter will be modified by the virus, causing the memory value to be inconsistent with the actual memory size of the memory, during use, the system crashes.
Solution: first, use the latest anti-virus software to completely eliminate viruses in the system. Due to virus infection in CMOS, the default value can be restored after CMOS is discharged. The method is to first discharge the CMOS transient connection, restart the machine, enter the CMOs, carefully check the hardware parameters, and correctly set the parameter values related to the memory.
9. Upgrade the computer to expand the memory. The memory is not compatible with the motherboard.
Solution: Before upgrading the memory of your computer, you must carefully check the usage instructions of the main board. If the main board does not support a memory larger than MB, it will not work properly even after the upgrade. If the motherboard supports this function, but the compatibility of the motherboard is poor, you can upgrade the BIOS of the motherboard to see if it can solve the compatibility problem.
