Memory faults and Analysis
I. No display at startup
This type of fault occurs due to memory stick, which is generally caused by poor contact between the memory stick and the memory slot of the motherboard (on the premise of eliminating the memory failure ), you only need to use an eraser to re-try the golden finger part to solve the problem (do not use alcohol or other cleaning), there is a memory damage or motherboard memory slot problems will also cause such a fault.
No Display fault caused by memory stick, host speakers generally beep for a long time (for Award BIOS)
II. The windows system is unstable and often produces illegal errors
This type of fault is generally caused by poor memory chip quality or software reasons. If it is determined that the memory is the only reason for replacement.
Iii. Windows Registry is often damaged without reason, prompting users to recover
This type of failure is generally caused by poor memory quality and is difficult to repair. Only one change is needed.
4. Windows often enters security mode automatically
This type of fault is generally caused by incompatibility between the motherboard and the memory stick, or poor quality of the memory stick. It is commonly used on some boards that do not support the pcw.memory stick, you can try to reduce the memory read speed in the CMOS settings to see if the problem can be solved. If not, you have to replace the memory.
5. Random crash
This type of fault is generally caused by the use of several different chips of memory, because the speed of each memory is different, resulting in a time difference, resulting in a crash, this can be solved in the CMOS settings to reduce the memory speed, otherwise, only the same type of memory is used. Another possibility is that the memory stick is not compatible with the motherboard. This kind of phenomenon is generally rare, and it may also be caused by poor contact between the memory stick and the motherboard, causing Random computer crashes. This kind of phenomenon is quite common.
6. Reduced system resources when the memory size increases
This type of phenomenon is generally caused by incompatibility between the motherboard and the memory. It is common in the case that the pcw.memory stick is used on some boards that do not support the pcw.memory stick. The problem cannot be solved even if the system is reinstalled.
7. When Windows is started, the system prompts a problem with some addresses when loading the high-end memory file himem. sys.
This problem is generally caused by some chip damage of the memory stick. For the solution, refer to the memory maintenance method below.
8. There are frequent prompts of insufficient memory when running some software.
This phenomenon is generally caused by insufficient space on the system disk. You can delete unnecessary files and leave more space. Generally, it is recommended to keep it around MB.
9. When Windows is installed on the hard drive and disk space is detected, the system prompts insufficient memory.
This fault is caused by the user adding the emm386.exe file to the config.sysfile. You only need to block it to solve the problem.
In fact, it is complicated and slow to Boot Windows from the hard disk in DOS mode. First, you must install the DOS file on the hard disk and configure config. sys and autoexec. if the BAT file is improperly configured, a series of unforeseen faults may occur, which is not practical for beginners. Second, after Windows is loaded successfully, the configuration will be transferred every time the system is started. sys and autoexec. BAT file to drive the optical drive, so that the system startup time is extended, if the config is blocked. sys and autoexec. after bat, sometimes the optical drive does not work normally in windows.
10. An invalid error occurs during System Configuration During Windows installation.
This type of fault is generally caused by memory damage. You can solve it by using the memory maintenance method. If not, you only need to replace the memory.
11. The system automatically restarts multiple times when Windows is started.
This type of fault is generally caused by memory stick or power quality problems. Of course, system restart may also be caused by poor CPU cooling or other manual faults. In this case, only the exclusion method can be used to eliminate the problem step by step.
12. Memory Maintenance Method
In the case of the above faults, if the memory is damaged or the chip quality is not good, if the conditions are not allowed, you can use a soldering iron to detach each chip on the memory side to check whether the problem can be solved, if not, unload another chip until it succeeds (so the welder is only afraid that the mobile phone will be repaired ). Of course, if you have the conditions to use an oscilloscope for detection, you will get twice the result.) After using this method, because one side of the memory chip has been removed, only half of the memory is available. For example, 64 m and 32 m are available, to this end, there is no need for repair for small memory capacity.
Be careful when repairing the memory to avoid destroying the entire memory chip!
