What is the reason that the computer often has a blue screen

The hardware reason and resolution
of blue screen




"blue screen" phenomenon and memory size, CPU frequency, optical drive, hard disk fragmentation and so on close relationship ... When you use a computer, you often encounter a blue screen. For beginners, it seems like a computer disaster, like a helpless. In fact, as long as you understand the cause of the need not to be afraid. There are many reasons for the computer blue screen, and the hardware can be summed up in the following ways:





One, screen display system busy, press any key to continue ...





1, the virtual memory is not enough to cause the system multi-task operation error


virtual Memory is a unique method of Windows system to solve the problem of system resources, it generally requires that the main boot zone's hard disk space is 2-3 times its physical memory. And some enthusiasts in order to make full use of space, their hard drive to cram full, busy remember windows this demanding requirements. As a result, the virtual memory caused by the lack of space on the hard disk error, so the blue screen appears. To solve this problem is simple, try not to put the hard disk full, to frequently delete some of the system generated temporary files, exchange files, so you can free space. Or you can manually configure virtual memory, select Advanced, the default address of virtual memory, go to other logical disk. This avoids the blue screen caused by a lack of virtual memory.





2, CPU overclocking results in operational errors


overclocking is common to enthusiasts, so the various malfunctions caused by overclocking are inevitable. Overclocking, in itself, is based on the original to achieve higher performance, but because of overloading operations, resulting in excessive internal operations, so that the CPU overheating, resulting in system operation errors. Some CPUs have better overclocking performance, such as Intel's Celeron processor and Amd-k6-2 processor, but sometimes there are some inexplicable errors. (For example: I've tried the Intel Celeron 300A, when overclocking to 450, the floppy disk drive does not accept the command, when the read disk operation). Intel's less than 200 CPU and AMD-K5 overclocking capabilities are not that good. Recommended high-end CPU to overclocking, then the thermal work must be done well, it is best to install a large fan, coupled with some of the thermal materials such as silica. As for some low-grade CPUs I suggest you better not to overclocking, so that overclocking can not achieve the desired effect but often blue screen affects the normal speed of the computer. 3lian.com





Second, the memory of the incompatibility or damage caused by the operation error





This is the most intuitive phenomenon, because this phenomenon is often in a boot when you can see, not start the computer, the picture prompts a memory problem, ask you whether to continue. This error is caused by physical damage to memory or by incompatible memory with other hardware. At this time only another memory has been replaced.





three, the CD-ROM drive is not normally opened when the disk





This phenomenon occurs when the optical drive is reading data, the blue screen is caused by the operation of the error. This problem does not affect the normal operation of the system, as long as the disc or press the ESC key can be.


above are some of the reasons why I run into a blue screen in my maintenance computer, and maybe there are some other puzzling problems that cause the computer to appear blue screen. In any case, after this type of problem, you should carefully analyze the cause of the problem before you begin to solve it.





Four, hardware surplus space is too small or too much debris





because the Win9x run needs to use hard disk as virtual memory, this requires that the hard disk must retain a certain free space to ensure the normal operation of the program. Generally speaking, the minimum should ensure that more than 100MB of space, otherwise the "blue screen" is likely to be too small with the hard disk space. In addition, too much fragmentation of the hard disk, but also easy to cause "blue screen" appearance. Therefore, it is necessary to defragment every once in a while.





Five, System hardware conflict





This phenomenon causes "blue screen" is also more common. In practice, you often encounter the setting of a sound card or a display card. In the control Panel → system → device management check for a device with a yellow question mark or exclamation point, such as the existence can try to remove it first, and restart the computer, automatically adjusted by Win9x, can generally solve the problem. If not, you can manually adjust or upgrade the appropriate driver.




The software reason and solution
of
"blue screen"




and hardware are closely related to the software, sometimes the software in the "blue screen" phenomenon is also "work not", loading too many programs, registry problems, soft and hard incompatibility, driver problems, relative to the hardware reasons to be difficult to detect, you should pay more attention to ...





One, the loading program at startup too





do not load too many applications at startup (especially if your memory is less than 64MB) so that system resources are not exhausted. Under normal circumstances, the system resources should not be less than 90% after Win9x boot. It is best to maintain more than 90%, if not run after starting any program is less than 70%, you need to unload a part of the application, otherwise it may appear "blue screen."





second, the application has bugs





Some application designs have flaws or errors that may conflict with Win9x or compete for resources, causing Win9x to not be able to allocate memory addresses or encounter their protective errors. This bug may be unpredictable and free software is most common. In addition, because some users are still using pirated software (including pirated Win9x), these pirated software in the decryption process will destroy and lose part of the source code, so that the software is very unstable, unreliable, and often lead to "blue screen."





III, by unknown procedures or virus attacks





this phenomenon as long as we are in the Internet when we encounter, when we surf, especially in some BBS station, may expose their own IP, "hackers" with some software attacks. The best thing to do with each other is to install some defensive software on your own computer. Then there is to login BBS to make security settings, hide their own IP.





IV. Version Conflict





Some applications need to invoke a specific version of the dynamic-link library DLL, and if the old version of the DLL overwrites the new version of the DLL when the software is installed, or if the application is deleted by mistakenly deleting the useful DLL file, the above call may fail and a "blue screen" appears. You may wish to reinstall and try again.





Five, there is an error or corruption in the registry





In many cases this is the main reason why the "blue screen" appears. The registry holds important data such as Win9x hardware configuration, application settings, and user information, and is likely to appear "blue screen" if there is an error or damage to the registry. If your computer often appears "blue screen", you should first consider the registry has a problem, should be timely detection, repair, to avoid greater loss.





VI, hardware and software incompatible





new technology, hardware development quickly, if the installation of new hardware often appear "blue screen", which is mostly related to the motherboard BIOS or driver too old, so that the hardware can not be well supported. If your motherboard supports BIOS upgrades, you should upgrade to the latest version or install the latest device drivers as soon as possible.
