1, crash after modifying BIOS settings.
Problem Description: Modifying BIOS can optimize system performance. Why is the system unstable after I change the BIOS settings according to the skills introduced in computer newspapers and periodicals?
Solution: modifying the BIOS is definitely the patent of "super user". Some novice users are eager to learn. After reading some articles, in order to improve and optimize their system performance, they often modify some setting parameters in BIOS, such as hard disk parameters, memory parameters, CPU parameters, chipset parameters and so on. However, some technical articles are wrong in themselves, and the meaning expressed is easily misunderstood or the scope of application is limited. When the default settings of the computer are modified, the system becomes unstable and often crashes, but at the same time it can't enter the Windows system at all. For this kind of fault, it is usually only necessary to modify the BIOS settings accordingly or simply restore the default values.
2. Deleting system files by mistake leads to system crash.
Problem description: I am a "novice". In order to save hard disk space, I deleted some "irrelevant files" in the Windows directory, so I can't get into the operating system when I reboot.
Solution: Some important system files in "C:Windows" directory and its subdirectories are deleted by mistake or accidentally lost or damaged, which will lead to frequent system crashes or no access to the system at all. For this kind of fault, it is sometimes difficult to recover the system directly. The simplest solution is the cover the installation window, that is, reinstall Windows in the original installation directory without formatting the Windows partition.
3, abnormal shutdown caused by the crash
Problem description: Sometimes the computer shuts down abnormally (such as sudden power failure), and colleagues around me remind me that this will cause a crash and damage the hard disk. Is it true?/You don't say.
Solution: Windows automatic shutdown program is not needed. Usually, an illegal shutdown will not cause much damage (because the probability of failure is not great), but if it is shut down illegally for a long time, it may cause file damage and loss, unstable system operation and even hardware damage. In addition, sometimes this illegal shutdown is likely to cause logical errors in the hard disk and frequent crashes. Fortunately, after the illegal shutdown, the system will automatically scan the disk, correct errors and eliminate hidden dangers, but some people will skip it and prevent the system from checking automatically. It is recommended not to do this, or you will regret it if there is a track with bad logic.
4. Hot-plug hardware equipment leads to crash.
Problem description: Now all hardware supports "hot plug", but why can some hardware be damaged by direct hot plug?
Solution: With the development of science and technology, many devices now support hot plug, such as USB devices and 1394 devices. However, according to practical experience, most hardware operations should be completed in the power-off state, otherwise it is likely to cause system crash or even permanent hardware damage. The crash caused by hot plug can make the system run again by restarting the computer without causing hardware damage. However, it is recommended not to hot plug conventional hardware devices. After all, for individual users, "security" is paramount.
5, overclocking caused the crash.
Problem description: Why is overclocking so easy to cause a crash?
Solution: Many DIY experts like to overclock all kinds of hardware, some are single-CPU, and some are super-everything. Taking CPU overclocking as an example, the speed of CPU accessing data in memory is faster than the speed of exchanging data between memory and hard disk. Overclocking makes this contradiction more prominent, exacerbates the situation that the required data cannot be found in memory or virtual memory, and will lead to "abnormal errors". In addition, if you run large-scale software (such as 3D games) for a long time or multitask after overclocking, the temperature of the CPU chip is likely to exceed the normal working range, leading to system crash or restart. Excessive temperature may also cause electrons to drift and damage CPU. So overclocking can improve the system performance, but it will also reduce its stability. Of course, the solution is just to reset the operating frequency of each device to the default value. If it must be exceeded, the cooling system must be checked regularly or the cooling work must be strengthened. When overclocking, the frequency should not be too high, and do not pursue overclocking in summer.
