performance analysis of memory failure:
First, no display on the boot
Because of the memory of the reasons for this type of failure is a common phenomenon, generally because the memory bar and the motherboard memory slot caused by poor contact (in the exclusion of memory itself failure of the premise), as long as the eraser back and forth to wipe the gold finger parts can solve the problem (do not use alcohol, etc. There is also the memory corruption or motherboard memory slot problems can cause such a failure.
Due to the memory of the cause of the boot-free failure, host speakers will generally be long time beep (for Awardbios)
Second, the Windows system operation is unstable, often produce illegal error
This type of failure is generally due to poor quality of memory chips or software causes, if the determination is the reason for the memory is only replaced one way.
Third, the Windows registry is often damaged without cause, prompting for user recovery
Such failures are generally due to poor quality of memory, it is difficult to repair, only to replace one way.
Four, Windows often automatically enter Safe mode
This type of failure is generally due to the motherboard and memory stripe incompatible or bad quality, common in PC133 memory for some do not support the PC133 memory of the motherboard, you can try to reduce the memory reading speed in the CMOS settings to see if the problem can be solved, if not, then only replace the memory bar.
V. Random crash
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.
Six, the memory increases after the system resources decrease
This type of behavior is typically caused by a motherboard that is incompatible with memory, and is common in PC133 memory strips on motherboards that do not support PC133 memory, even if system reloading does not solve the problem.
Seven, when Windows starts, when loading the high memory file Himem.sys system prompts certain address to have the problem
This problem is typically caused by some chip damage to the memory bar, and the workaround can be seen in the following memory repair method.
Eight, running some software often appear 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.
Nine, from the hard disk boot installation windows to detect disk space, the system prompts for insufficient memory
This type of failure is generally due to the user in the Config.sys file added Emm386.exe file, as long as the shield can solve the problem.
In fact, booting from the hard drive to install Windows in DOS is complicated and slow, one of which is that you have to install a DOS file on your hard disk. and also to configure Config.sys and Autoexec.bat files, if the file is improperly configured, it will also cause a series of unforeseen failures, for beginners is not practical. Second, after Windows loads successfully, Because each boot system will be transferred into the Config.sys and Autoexec.bat files to drive the drive, making the system boot time extended, if the screen off Config.sys and Autoexec.bat, there is time drive under Windows and can not work properly.
X. Installing Windows to 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.
XI. 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.
12. Memory Maintenance One method
After several failures appear, if the memory damage or chip quality is not allowed, such as the condition does not allow the memory side of the chip to unload, to see if the problem can be solved, if not to replace the chip on the other side, until successful (so the welder is afraid to repair the phone's people can reach). Of course, conditional use of oscilloscope detection that will be more than half the effort, after this method, because the memory side of the chip is removed, so the memory is only one-half available, for example, 64M also has 32M available, for small capacity memory there is no need for maintenance.
