Many users are at a loss when encountering a blue screen when using Windows 7. In fact, the blue screen is not terrible. The editor below will tell you how to deal with the blue screen and the solutions.
1. The meaning of Windows 7 blue screen
1. Fault check information
***STOP 0x0000001E(0xC0000005, 0xFDE38AF9, 0x0000001, 0x7E8B0EB4) KMODE_EXCEPTION_NOT_HANDLED ***
The line above explains:
The first part is the stop code (Stop Code), which is STOP 0x0000001E, which is used to identify the type of error that has occurred.
The second part is a set of four numbers enclosed in parentheses, representing random developer-defined parameters (this parameter is simply incomprehensible to ordinary users, only driver writers or Microsoft operating system developers understand it).
The third part is the error name. The first line of information is usually used to identify the driver or device that produced the error. Much of this information is terse, but stop codes can be used as search terms in the Microsoft Knowledge Base and other technical resources.
2. Recommended operations
The second part of the blue screen is the recommended operation information for the user. Sometimes the recommended action is just a general suggestion; sometimes it's a prompt relevant to the problem at hand. Generally, the only advice is to reboot.
3. The debugging port tells the user whether the memory dump image is written to the disk. Using the memory dump image can determine the nature of the problem. It also tells the user whether the debugging information is transmitted to another computer manufacturer and what port is used. Complete this communication. However, the information here is meaningless to ordinary users. Sometimes the security department can successfully find out which production group has the problem, and will clearly report in the first part which file the error is from, but often it can only check the general scope and cannot clearly identify the problem. Because the factory is forced to stop completely and has to be reorganized and restarted, sometimes the production team will realize the mistake and not make it again. But sometimes they still try to snatch parts, so the factory leaders have to repeat the decision to stop work (cannot start and display a blue screen message, or a blue screen appears again when performing the same operation).
2. How to deal with Windows 7 blue screen
There is a lot of Windows 7 blue screen information, which cannot be fully explained in one article, but their causes are often concentrated in incompatible hardware and driver problems, software, viruses, etc. When encountering a blue screen error, you should first check the following Plans are excluded.
1. Restart
Sometimes it's just a program or driver that makes a mistake and they correct it after a reboot. (Note: See 7. Query the shutdown code at this time)
2. New hardware
First of all, you should check whether the new hardware is plugged in securely. This issue that many people ignore often causes many inexplicable failures. If there is no problem, unplug it, try another slot, and install the latest drivers. At the same time, you should also check whether the hardware is compatible with the operating system according to the hardware compatibility category on the Microsoft website. If your hardware is not in the list, check the hardware manufacturer's website or call their consultation hotline.
3. New drivers and new services
If you have just installed a new driver for a certain hardware, or installed a certain software, and it has added corresponding items to the system services (such as anti-virus software, CPU cooling software, firewall software, etc.), it will appear during restart or use. In case of blue screen failure, please go to safe mode to uninstall or disable them.
4. Check for viruses
For example, viruses such as shock wave and oscillation wave can sometimes cause a blue screen of death in Win7, so virus detection is essential. At the same time, some Trojans and spyware can also cause blue screens, so it is best to use relevant tools to scan and check.
5. Check BIOS and hardware compatibility
For newly installed computers that often have blue screen problems, you should check and upgrade the BIOS to the latest version, and turn off memory-related items, such as caching and mapping.
In addition, you should check your hardware against Microsoft's hardware compatibility list. Also, if the motherboard BIOS cannot support large-capacity hard drives, it will also cause a blue screen and needs to be upgraded.
Tips:
BIOS cache and mapping items
Video BIOS Shadowing
Shadowing address ranges (mapping address columns)
System BIOS Cacheable (system BIOS cache)
Video BIOS Cacheable (video BIOS buffer)
Video RAM Cacheable (video memory buffer)
6. Check the system log
Enter: EventVwr.msc in the Start->menu and press Enter to display the "Event Viewer". Pay attention to check the items indicating "Error" in the "System Log" and "Application Log".
7. Query the blue screen code
Write down the dense E-texts in the blue screen, then go online to another computer and enter the Microsoft Help and Support website http://support.microsoft.com . Enter the shutdown code in "Search (Knowledge Base)" in the upper left corner. If you search If there is no suitable information in the result, you can choose "English Knowledge Base" to search again. Typically, you'll find useful solutions here. In addition, using the blue screen shutdown code or the following explanatory text as a keyword search in search engines such as Baidu and Google will often yield unexpected results. Everyone must know this.
8. Last Known Good Configuration Under normal circumstances, blue screen appears after updating the hardware driver or adding new hardware and installing its driver. At this time, the "Last Known Good Configuration" provided by Win7 is a shortcut to solve the blue screen. Restart the system,
When the boot menu appears, press the F8 key to display the advanced boot options menu, then select "Last Known Good Configuration".
9. Install the latest system patch. Some blue screens are caused by defects in Windows 7 itself. You can install the latest system patch.
3. Windows 7 Blue Screen of Death Analysis and Solutions
When using Windows 7, you often encounter the phenomenon of blue screen. For beginners, it seems like a computer disaster and they are at a loss. In fact, as long as you understand the cause, you can prescribe the right medicine. There are many reasons for blue screen, which can be summarized as follows:
1. The screen shows that the system is busy, please press any key to continue...
1) Insufficient virtual memory causes system multi-task operation errors
Virtual memory is a method unique to Windows systems to solve the problem of insufficient system resources. It generally requires that the remaining space of the hard disk in the main boot area is 2-3 times the physical memory. In order to make full use of the space, some enthusiasts fill their hard drives to capacity and forget about the demanding requirements of Windows. As a result, the virtual memory has an operation error due to insufficient hard disk space, so a blue screen appears. To solve this problem is very simple, try not to fill up the hard disk, and frequently delete some temporary files and swap files generated by the system to free up space. Or you can manually configure the virtual memory, select Advanced, and transfer the default address of the virtual memory to another logical disk. This avoids blue screens caused by insufficient virtual memory.
2), CPU overclocking leads to operation errors
Overclocking is a common thing for enthusiasts, so various failures caused by overclocking are inevitable. Overclocking itself is to achieve higher performance on the original basis, but due to overloading operations, too many internal operations are caused, causing the CPU to overheat, resulting in system operation errors. Some CPUs have better overclocking performance, but sometimes some inexplicable errors may occur. (It is recommended that when the CPU is overclocked, the heat dissipation work must be done well. It is best to install a large fan and some heat dissipation materials such as silica gel.)
2. Incompatible or damaged memory modules cause operation errors.
This is the most intuitive phenomenon, because this phenomenon can often be seen when the computer is turned on. The computer cannot be started at all. The screen prompts that there is a memory problem and asks you if you want to continue.
This error is caused by physical damage to the memory or incompatibility between the memory and other hardware. At this time, the only option is to replace another memory.
3. Attacked by unknown programs or viruses. This phenomenon usually occurs when we surf the Internet. When we surf, especially when entering some BBS sites, our IP may be exposed and we may be attacked. "Hackers" use some software to attack. The best way to deal with this situation is to install some defense software on your computer. Another thing is to set up security settings and hide your IP when logging into BBS and other public places.
4. The system is bloated
For example: There are too many application software installed on the Windows 7 system, especially those applications that start up with the system. A blue screen often appears during the system startup process. This situation is mostly caused by application shared memory conflicts! So it is best not to add applications to the startup group.
5. The optical drive was opened abnormally when reading a disk.
This phenomenon occurs when the optical drive is reading data and is opened by mistake, resulting in a blue screen. This problem does not affect the normal operation of the system, just eject the CD or press the ESC key.
The above are commonly encountered situations. There may be other inexplicable problems that cause a blue screen on the computer. In any case, when encountering this kind of problem, you should carefully analyze the cause of the problem before starting to solve it. I hope the above points can be helpful to my friends.
