Troubleshooting of seven major Windows systems

I believe that almost everyone has encountered various errors and problems while using Windows. In addition to Microsoft programmers, people can only swallow the bitter water into their stomachs. When people encounter similar problems, they seem to get used to it. They often press a "Press ENTER" or "cancel" to wait for a while, and silently pray to "Amitabha" After restarting the computer ". In fact, this approach is not advisable, and it may lead to a big mistake at any time. Next let's analyze and discuss such issues.
1. "blue screen" error

Q: It is common for the system to display a blue screen and some error messages during use. Although the error message may contain instructions such as "press any key to continue" and "press Ctrl ten Alt + Del to restart, all unsaved information will be lost, but it usually does not continue or restart as it said. In many cases, the system crashes, and there is almost no other choice except to press the reset button. Why do blue screens appear frequently?

A: There may be many causes of blue screen errors in Windows. For example, if multiple large programs are run at the same time, and the system memory is relatively small, at this time, the system may prompt "Windows is busy" (the system is busy) Wrong blue screen information, this is caused by insufficient memory. In addition, some defective programs may have blue screen information with a "Fatal exception" error in Windows, and may also indicate that the XX file has an error at a specific address. Of course, there are also many hardware reasons, such as hardware incompatibility or damage, which may lead to incorrect operations, overclocking, or system overheating. There is also an inconspicuous error that will make Windows blue screen, that is, when the system reads data from a floppy disk or a CD, it will remove the floppy disk or open the drive door.

2. "invalid operation" prompt

Q, A saying "XX program has executed illegal operations and is about to shut down" suddenly jumps above the screen, making a few hours of painstaking efforts idle and disappointing. Can you tell me the specific reason?

A: during computer operations, the "illegal operations" prompt is more likely than the blue screen. The reason for "illegal operation" is mainly from the software. When a program accesses the memory outside its memory address space, it will cause a system error. In addition, because Windows cannot reasonably allocate and recycle memory resources, some software cannot obtain the corresponding memory address during runtime. When an "invalid operation" prompt appears, the following "details" button will indicate the error code, you can use a small tool MS Windows Eror Messages(_2660.htm "> http://soft.winzheng.com/SoftView/SoftView_2660.htm) to view the specific meaning of invalid operation error code.

3. "General Protection error" Notification

Q: during my computer operations, sometimes the system suddenly crashes and the screen prompts "General Protection Fault". After translation, the original machine encountered a "General Protection error". Why, how can this problem be solved?

A: The appearance of "general protective errors" usually tells you that a software installation has a problem or the driver of a hardware device needs to be updated. I have met twice: I accidentally spilled liquid into the keyboard when I was drinking coffee, and I felt that I didn't have to take the initiative to delete the related software for a long time, the system bluntly tells me that there is a general protective error. Obviously, the former is a hardware fault, while the latter is a software fault. If the cause cannot be found, we can use the Dr. watson tool provided by the system. If a program has an error, it can record the software environment at that time to help you determine the cause of the error. However, there is also a small trick: Generally, program conflicts or errors will be prompted, regardless of software or hardware reasons, will mention the error file, please use the search function to find this file, you can view the attribute to learn its description. The crux of the problem is found. reinstalling or upgrading the file will solve the problem.

4. "invalid page error" Announcement

Q: sometimes when I was operating on my computer, I suddenly came up with a prompt "Lnvalid Page Fault (invalid Page error)", which made me confused and confused. Why did this happen?

A: This error message usually occurs when data is transmitted between an application and a Windows system. Once an error occurs, the program may run an incorrect command, the final result shows "Lnvalid Page Fault (invalid Page error )". After this error occurs, check the hardware. For example, if the physical memory is too small, the virtual memory is unstable, the remaining hard disk space is too small, and the virtual memory is damaged or damaged by an application; A program attempts to improperly use the physical memory; an application attempts to access data being modified by another application, and so on. For the first two reasons, we recommend that you increase the memory and hard disk, or clear the hard disk to restore enough space. If it is another reason, the problem should not be serious. You can think about whether you have installed new software or changed the hardware configuration to find a clue.

5. Warning of "EXPLORER performing illegal operations"

Q: Recently, when my computer opened and closed the window, a message "EXPLORER has performed illegal operations" is often displayed. What is the problem? How can this problem be solved?

A: This is caused by system instability. There are many specific reasons, including hardware or software. First, you should check whether the system is infected with viruses. Then you can try to reinstall the new version of IE. If there are still problems, consider the hardware, generally, the accessories that are most likely to cause system instability mainly include memory, power supply, and motherboard. You can use replacement methods to find the root cause of the problem.

6. "Rundll32 error" Display

Q: During Windows operations, I often encounter the system prompt "Rundll32 error". If you press the "OK" button in the pop-up dialog box, the system will forcibly close the program in use; if you do not press the "OK" button, a dialog box with a Red Cross exists. Why is this solved?

A: DLL is a dynamic link library concept proposed by Microsoft. The principle is that the Code required by each program can be obtained from the same address, saving system space. However, this has become the biggest weakness of Windows: Applications will upgrade these databases to their own versions to make them run better during installation, in this way, other programs cannot be started even on Windows, and DLL becomes a "trap ". The possible cause of the Rundll32 error is the mmsystem in the operating system. dll files are damaged or lost. Copy them on other computers to overwrite them. In addition, it may be system. mmsystem. dll statements are lost. Solution: In the top menu of the system Configuration Utility window, select system. ini tag, locate the [boot] section, and add drivers = mmsystem. dll and save and restart the machine.

7. Advice on "ActiveX Control insecurity"

Q: When I open a file (such as my document), a message "ActiveX control is not secure, so this page may not be displayed correctly" appears ", there are two options: OK and give up. After selecting "OK", enter my document. The above information appears when selecting "Excel" in the Document. After selecting "OK", you can enter the document without affecting the file. Can you explain the reasons and solutions?

A: This is because ActiveX controls and plug-ins are disabled in your IE security settings, and the files you open contain this control, so a prompt will appear. Run "tools-Internet Options-security-Custom Level" in IE, set ActiveX controls and plug-ins to "enable", or directly select "Default level.
