Why did the computer suddenly show Beginning dump of physical memory on the blue screen?

Like other failures, blue screen faults can be divided into two aspects: Software and Hardware Based on their causes. Now we should follow the principles of "soft first" and "hard" to see the cause and solution of the fault!
I. Blue Screen Fault Caused by software
1. Blue Screen failure (including virus-caused) caused by damage or loss of important files ).
Instance: VxD (Virtual Device Driver) in Win98 or important files such as. dll dynamic Connection Library are lost, which may be serious and a blue screen warning will appear ".
Solution 1: Write down the lost or damaged file name and use the "Ext" command on the Win98 boot disk to extract and restore the damaged or lost file from the Win98 installation disk. The steps are as follows:
(1) boot the computer with the Win98 boot disk and press the "Ext" command at the prompt.
(2) After "Please enter the path to the Windows CAB files (a):" is displayed, enter the complete path of the Win98 installation package, for example, "F: \ pwin98 \ Win98 ", then press Enter.
(3) enter the missing file name you noted down after the prompt "Please enter the name (s) of the file (s) You want to extract:", such as "BIOS. vxD ", press Enter.
(4) After the decompression path prompts "Please enter path to extract to ('enter' for current directory):", enter the complete path to which the file will be extracted, such as "C: \ WINDOWS \ SYSTEM "and press Enter.
(5) The prompt "Is this OK? (Y/N): ", enter" Y ", and press Enter. The "Ext" program will automatically find the cab package in the installation disk and release the file to the specified location.
(6) restart.
Solution 2: Use anti-virus software to prevent viruses. Some viruses may damage the registry key and the registry should recover the backup before poisoning.
Solution 3: If the graphic interface can be started, you can reinstall the driver of the motherboard and video card, and perform "system file scan" to restore damaged or lost files. To scan system files, click Start/Program/attachment/system tools/system information/tools/System File Checker, and then scan the changed files.
2. Blue Screen caused by incorrect file pointing due to registry corruption.
Instance: unauthorized modification of the registry (including manual modification and automatic replacement during software installation). The phenomenon is that blue screen appears when the program is started or called, an error message is displayed on the screen (including the file name of the error ).
Solution 1: Restore the backup.
(1) Click Start/shut down/restart the computer and switch to MS-DOS mode, and then click yes ";
(2) Go to the Windows directory. For example, if your windows is installed in the "C: \ Windows" directory, enter "cd c: \ Windows" and press Enter;
(3) type "scanreg \ restore" and press Enter.
(4) follow these steps to restore the registry to the last time the computer was started.
Solution 2: delete the key value.
If a blue screen appears after the program is uninstalled, the author determines that the fault is caused by incomplete program uninstallation. It is very easy to solve this type of problem. First you need to write down the wrong file name, and then find the following branch "HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ VxD" in the registry ". In "Search", enter the file name and delete the key value. Do not forget to back up the registry!
Typical Case: When I deleted Kingsoft drug overlord, I crashed. After I restarted it, I saw a blue screen on the desktop icon, accompanied by an error message. The kavkrnl. VxD file cannot be found in the error message. The author first determines that the file is not a Win98 System File Based on the first two characters in the file name, And ka starts with Kingsoft drug overlord's Virtual Device Driver. Basically, it is determined that the file points to an error, so it decides to delete the corresponding key value in the registry. In the Registry Editor search, enter "kavkrnl. VxD" and delete the corresponding primary key value in "HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ VxD". After restart, the fault is eliminated.
3. "blue screen" caused by system. ini file error ".
Instance: an error occurs when the system. ini file is not updated immediately after the software is uninstalled or installed.
Solution: Disable the entry in the registry or reinstall the corresponding software or driver.
4. The blue screen caused by imperfect Win98.
Example: The sp1of win98and the vxd_fix.exe patch of microsoftplay a vital role in the stability of Win98.
Solution: Download the SDK. For example, click [url] http://nj.onlinedown.net/win98sp1.htm#/url] win98sp1 and [url] ghost on the website of Nanjing.
5. Blue Screen Fault Caused by system resource depletion.
Instance: a blue screen fault often occurs when a relatively large task is performed, or when the copy is saved, and often occurs suddenly. This type of fault occurs mainly because of the usage of three heap resources (system resources, user resources, and GDI resources.
Solution: Open your resource status monitor and check the remaining resources. If all three resources are 50% or even lower, such as illegal operations, blue screens, or crashes. To this end, you must reduce resource waste and unnecessary program loads to avoid running large programs (graphics, sound, and video software) at the same time, such as loading scheduled task programs, input methods, and sound indicators, sound Card dos driver, system monitor program, and so on.
6. A blue screen Fault Caused by DirectX problems.
Example: (1) the DirectX version is too low or too high; (2) the game is incompatible with it or not supported; (3) the auxiliary important file is lost; (4) the video card is not supported.
Solution: upgrade or reinstall DirectX. If the video card does not support later DirectX versions, it means that your video card is too old to update the bios and driver of the video card. Otherwise, you have to spend money to upgrade the video card.
Ii. Blue Screen Fault Caused by hardware
1. Blue Screen caused by memory overclock or instability.
Instance: Random blue screen.
Solution: Run it at normal frequency first. If any problem persists. Find a good memory stick to replace the fault, which can be solved in general. Pay attention to the memory heat dissipation when the CPU is very close to the memory.
2. Blue Screen caused by poor hardware compatibility.
If the compatibility machine is good, it is better that it is cost-effective. If it is bad, when it is being assembled, users cannot perform a series of compatibility tests due to lack of sound monitoring methods and corresponding knowledge, in this way, the hidden risks will remain in the future use process.
Instance: A Fault Caused by mixed insertion of memory strips of different specifications during memory upgrade.
Solution: Pay attention to the differences between memory stick manufacturers, memory particles, and batch numbers. It is often because of the different memory stick parameters that lead to a blue screen or a crash, even more serious memory faults. You can also change the slot position of the memory stick. If the memory stick still does not work properly, you have to replace it. Here, I would like to remind you that the entire microcomputer system plays a very important role, and its quality will directly affect the stability of the system. Therefore, pay attention to the memory purchase, it is best to be accompanied by an inner, to avoid buying remark comments or too frequent comments.
3. "blue screen" Fault Caused by hardware cooling.
Example: faults that occur in the heat dissipation of a microcomputer often have certain rules. Generally, the fault occurs after the microcomputer runs for a period of time, and the result is a blue screen crash or a random restart. The main cause of the failure is Data Reading and transmission errors caused by overheating.
Solution: Adopt overclocking to reduce the frequency and temperature. In fact, not all faults are so complicated. Sometimes, from a simple perspective, we can also solve problems well and learn to bypass them.
4. Blue Screen caused by I/O conflicts.
Solution: this phenomenon rarely occurs. If so, you can delete the band from the system! Number or? Device Name, restart the computer to confirm, or manually assign system resources.
The following are some of my experiences for your reference:
1. Regular manual backup of important registry files to avoid irreparable errors caused by failure to be replaced with backup files in a timely manner after system errors.
2. Avoid abnormal shutdown to reduce the loss of important files. Such as. VxD. DLL files.
3 For normal users, as long as they can run normally, there is no need to upgrade the graphics card, motherboard BIOS and driver, to avoid the hazards caused by the upgrade.
4. Regularly check and optimize system files and run the "System File Checker" to check file loss and verify the version. For more information about the check procedure, see the previous section.
5. Reduce the installation of useless software. Do not manually uninstall or delete the program to reduce the occurrence of invalid replacement files and file pointing errors.
6 if the memory is not very large and the management program is very good, try to avoid running large programs at the same time. If you find that listening to MP3 is a saraara sound, it can be determined that the fault is caused by insufficient memory.
