Memory FAQ Solution Rollup

Memory as one of the computer three piece accessories, with the task of temporary access to data. In the use of the process, there will inevitably be some problems, such as the start of the computer can not start the normal, can not enter the operating system or running the application software, no reason often crashes and other failures, these problems are usually due to the memory of abnormal failure caused by operation failure. Memory problems are partly due to the upgrade of memory, because of the type of memory mismatch, often encounter some problems; the other part is the memory in use, the gold finger and the motherboard slot contact bad cause or is a virus and other causes caused by the problem. In addition, the quality of the memory in the market is uneven, also cause some memory failure. Now to facilitate the solution of these memory problems, the author will be a number of common problems and solutions summarized, I hope you can help convection.

1, no display on the boot. This type of failure is usually due to poor contact with the motherboard memory slot, as long as the eraser and rub the gold finger parts can solve the problem (do not use alcohol and other cleaning), there is memory damage or the motherboard memory slot problems will cause such failures. The host speaker will generally beep for a long time (for the award BIOS) due to a memory-strip cause of boot-free failure.

2, Random panic. Such failures are generally due to the use of several different chips of the memory, due to the different speed of each memory to produce a time difference resulting in a panic, this can be in the CMOS settings to reduce memory speed to be resolved, otherwise, only the use of the same model of memory. There is also a possible memory is not compatible with the motherboard, such a phenomenon is generally rare, but also may be the memory of the board and the motherboard bad contact caused by random computer crashes, such phenomena are relatively common.

3, not normal boot. There are three main solutions to this phenomenon: first, the location of the replacement of memory, this is the simplest and most commonly used a method, is generally the low speed of the old memory in the position of the front. Second, in the basic can boot on the premise, into the BIOS settings, the memory-related settings according to the low Speed memory specifications set. For example: Use one of the memory (if it is a mix of DDR333 and DDR400 memory, it is best to use DDR333 memory to start the computer, enter the BIOS settings, the operating frequency of the memory and reaction time slow, with the old memory can be stable operation, before the shutdown can be plugged into the second memory.

4, the computer operation is not stable. Encountered this type of problem is mainly due to memory compatibility, the basic idea of the solution is the same as above. First, replace the memory location. Second, in the BIOS to turn off the memory by the SPD automatic configuration option, changed to manual configuration. Third, if the motherboard with I/O voltage regulator, the voltage can be properly adjusted to enhance the stability of the memory.

5, running some software often appears to be low memory tips. This phenomenon is generally due to the system disk space is not enough, you can delete some useless files, more space can be left, the general stay in the 300M or so advisable.

6. The memory capacity is not correctly identified after the mixer is plugged in. Cause of this phenomenon, the first may be the motherboard chipset itself caused by the reasons, some old motherboards only support 256MB memory capacity (i815 series only support 512MB), beyond the parts are not recognized and used. There are also cases where the motherboard cannot support high memory particles, and the only way to solve such problems is to replace the motherboard or memory. In some cases, you can also resolve this problem by adjusting the insertion order of the memory.

7, the computer can not start normally, turn on the computer host power supply chassis alarm horn after a long period of short sound, or open the host power after the computer may start but not normal access to the operating system, the screen appears "error:unable to ControlA20 Line" error message and panic.

Most of the above failures are caused by poor contact between the memory on the motherboard. The solution is to unplug the memory after opening the chassis, using alcohol and clean paper towels to wipe the memory of the gold fingers and memory slots, and check the memory slot for signs of damage, wipe the test after the end of the memory reinsert, the general problem can be resolved, if still unable to power on the memory unplugged into another memory slot test , if the problem persists, the memory is corrupted and only new memory strips can be replaced at this time.

8. Installing Windows to the system configuration creates an illegal error. This type of failure is usually due to the memory of the damage caused by the maintenance of a method to solve the memory, if not, it will only replace the memory bar.

9, after the boot display the following information: "On BOARD parlty ERROR."

There are three possible reasons for this phenomenon: first, the parity in CMOS is set to be valid, while the memory strip has no parity on the test bit. Second, the parity on the motherboard is more faulty than the test circuit. Third, the memory stripe is damaged, or bad contact. Processing method, first check the CMOS in the relevant items, and then plug in the memory to try, if the fault still can not disappear, it is the motherboard on the odd-even circuit failure, change the motherboard.

10, Windows system running in the DOS state of the application software (such as operating under DOS game software, etc.) when the black screen, Huati, frozen phenomenon.

This failure is generally due to the allocation between the software, occupy memory conflicts caused by the general performance of black screen, Huati, panic, the best solution is to exit the Windows operating system, in pure DOS state run these programs.

11, Windows operating speed significantly slower, the system has a lot of memory errors prompted.

This type of failure is typically due to the illegal access of the application running under Windows, the presence of too many unnecessary plug-ins in memory, the application, the opening of too many active windows, the unreasonable application-related configuration files, and so on, which can cause the system to slow down and even panic. The solution to this problem must be to clear some illegal plug-ins (such as 3721), memory-resident program, reduce the active window and adjust the configuration file (INI), etc., if the running of a program when the speed significantly slowed down, then you can reload the application method to solve, If the system slows down when you run any application or program, the best way to do this is to reinstall the operating system.

12. The system restarts automatically multiple times when you start Windows

This type of failure is generally due to the memory or power quality problems, of course, the system can also be restarted by the CPU or other man-made failure caused by this, the only way to eliminate the use of a step-by-step rule.

13, memory is infected with virus program resident memory, the size of the memory value of the CMOS parameter is modified by the virus, resulting in memory value and memory bar actual memory size, in the use of slow speed, system panic and so on. Source: Exam Network It College

The first use of the latest anti-virus software to the system for a comprehensive anti-virus treatment, thoroughly clean the system in the virus. Because of the virus infection in the CMOS, it is possible to restore the default value by discharging the CMOS. The method is to first the CMOS short connection discharge, reboot the machine, enter the CMOS after careful examination of the hardware parameters, correctly set the value of the memory parameters.
