In the process of using computers, it is impossible for us not to experience a system crash, even the simplest one.
Single daily operation may also bring some damage to the system. In fact, because people are using
Negligence in the use of computers-from software installation to random data copying-is possible.
Causes error prompts, system crashes and other problems.
System crash can be divided into three main situations:
First, software-induced crashes: even the simplest operations, such as installing programs and
Uninstalling may cause the system to crash.
2. Crash caused by the system itself: delete the DLL file, modify the registry, or
Please listen to our suggestions before upgrading the operating system.
Third, the collapse caused by hardware problems: computers are not furniture and need frequent maintenance.
We'll tell you what to do.
Here we list 18 common system crashes. In view of various situations, we also give
The countermeasures of identification, elimination and treatment are given.
(1) Even the best PC hardware is inseparable from software.
Hold-that is, what we usually call applications, operating systems and drivers. but
Today's software is becoming more and more complex and huge. Here we will tell you how to make you
Our machine runs more smoothly.
Do you often back up your system? No? at present
It is necessary to proceed! For some very important temporary documents (such as working documents and financial information)
It is not difficult to make a backup. If there is something wrong with the system, it will save you a lot of repetition.
Work. For small files, we can back them up to floppy disks, while for tens of megabytes of files and electricity,
Sub-tables, photo albums and video files can be backed up to Zip, Jaz, CD-R or CD-RW.
Medium.
If you think backup is troublesome, then you can compare it and appear in the system.
Problems (such as the loss of data on the entire hard disk due to a virus) will be recreated later.
Which is more troublesome in the west?
Countermeasures for deadly virus infection: people who have "download addiction" should pay attention to "vaccination" in time.
Because many new things are often downloaded from the internet, after installation and operation, there are suddenly many important things.
The file is inexplicably "without a trace"? What should I do?-Run the latest one without him.
Virus scanner! So when downloading the file, * * * opens the attachment in the email while enjoying the floppy disk.
When running the macro, please start the virus scanner. The best way to protect the "machine" of love from viruses.
The method is to scan every file you download and keep scanning for viruses at all times.
Execute in the background, and often upgrade the virus database to avoid giving new viruses an opportunity.
Countermeasures for abusing beta: Think twice before "downloading" xx software and releasing beta! Often.
Commercial software will release some test versions of software before the official version is released, because it usually
They are all free, so they are welcomed by some users. But "there is no such thing as a free lunch",
Test software usually contains some bugs or program errors that lead to system crash and data loss.
If you want the system to be more secure, don't download the early beta software immediately.
Load and use. It is best to wait for them to launch a higher version of the beta or formal demonstration version. such as
If you must use the latest beta software, you'd better at least back up your system.
Make a backup of the important work you are doing at present.
Countermeasures for illegal uninstallation: Step by step, all the Windows programs we installed will be in the system.
Or create a log file in the Windows Uninstaller utility.
In this file, you will record some files you added and the changes you made to the system configuration.
. When you use "Add/Remove" in the control panel or use the uninstall that comes with the program.
Program, Windows will delete all traces of this program in the system and system repair.
Change.
If you are not going to stop using a program, then you don't simply put it
Drag the folder to the Recycle Bin and finish. Instead, click Start-Setup-Control step by step.
Panel, then double-click the Add Remove icon, select the Install/Uninstall option, and finally double-click Remove.
Documents.
* * * Countermeasures: Easy upgrade. Most people think that there will be no problem with software upgrade.
Yes In fact, during the upgrade process, some components enjoyed by * * * will also be upgraded, but
However, other programs may not support the upgraded components, resulting in various problems.
In another case, the upgrade covers the * * * enjoyment module program that other software will use.
For example, if winsock.dll (a very important dynamic link library file for surfing the Internet)
Overwritten, programs that use this file will not be able to access the Internet. If you are interested in a piece of software,
To upgrade, please back up the files processed by this version and put in the old version of the program.
Uninstall, then install the new version and restore the previous backup.
Countermeasures for insufficient RAM: Free memory window can run multiple programs at the same time, but this will not work.
There is no guarantee that they can "* * * save * * * glory", especially if the system memory is not sufficient.
In this case. To find out the current utilization of system resources, you can open My Computer in.
Open the "About" menu under the "Help" menu, and you will find the utilization rate of system resources. If so
There are few resources left (below 20%), so be careful. At this time, you'd better close some unnecessary ones.
Join this project.
Memory leaks will waste some system resources. When you start a program, Windows will
It will be allocated a certain amount of resources (memory). After closing this program, Windows will return.
Collect resources. However, sometimes due to the problems of the program itself, memory resources cannot be recycled.
At this time, only restart the system. If you suspect that a program may have caused a memory leak, then
You can check the changes of system resources before and after opening/closing the program, if
After closing the program, the resources have not changed. You can find out if this program has been supplemented.
Ding Can fixes the leak.
(2) the collapse caused by the system itself, even the simplest operation, such as shutting down the system or
Even upgrading the BIOS may have a certain impact on your PC and operating system. such as
If you don't handle these processes properly, your computer may start abnormally or even fail to start at all.
However, if you know how to handle these operations correctly, you can protect them well.
Your computer is protected from crashing.
Countermeasures for BIOS damage: Do you need to upgrade the BIOS to back up the BIOS? So in
Before upgrading, it is best to determine whether the BIOS version you are using is consistent with your PC. If BIOS
If the upgrade is incorrect or an unexpected power failure occurs during the upgrade, your system may not be able to.
Let's begin. So be sure to know the BIOS model before upgrading the BIOS. If you are using the BIOS of.
The upgrade tool can back up the current BIOS, so please copy the previous BIOS on the disk.
Share it. At the same time, see if the system supports BIOS recovery (that is, boot block recovery), and also know how to
How to recover (there are some tools and software such as Rescue Disk of Norton utility.
Back up the BIOS and restore it in case of an error). If the BIOS upgrade fails,
The above steps can be resumed.
Countermeasures for poor file management: start Windows "self-treatment", although today's hard disk is making
The service life and stability have been greatly improved, but there are always files stored on it.
When there is a problem. File errors, such as file allocation unit errors (cluster loss) and staggered cluster links (this
This usually happens when multiple files use the same cluster block), and the general program crashes and a blue screen appears.
The image is caused by these two mistakes. In order to check and correct these file errors, you can check them once in a while.
Run ScanDisk every few weeks (Windows comes with its own program, which can be downloaded from
Start-Programs-Accessories-System Tools). Select the drive to scan and run.
It will be done in a minute or two. If you have enough time, you can also choose the option to fix the error.
There is also a common mistake here. When you create, delete, edit and change files
The cluster that stores these files will be scattered on the hard disk. This will cause Windows FAT.
The file system is "struggling" when reading and writing these "fragmented" files. In order to repair
To solve these problems, we can run the defragmentation tool every few weeks (yes
Found in Start-Programs-Accessories-System Tools) to reorganize the files on the disk.
So that cluster blocks containing files can be gathered together. After selecting the appropriate drive, you can start.
However, this process takes a long time.
Countermeasures for abnormal shutdown and restart: It is better to use the reset button less. Please don't use it before closing the window.
Shut down or restart the computer directly. Under normal circumstances, the program will open and create all kinds of non-.
Only when you have files (for example, virtual memory swap files and temporary files) can you shut down and restart normally.
Move, these files can be saved, or the files in memory can be saved to the hard disk.
However, if your laptop is already in a daze, even if you press Ctrl-Alt-Del, you will be numb.
If you are insensitive, you will have to press the reset button.
Windows disease countermeasures: upgrade, upgrade, upgrade!
Although Windows can "live in harmony" with most hardware and software, various errors and
Vulnerabilities are inevitable, so Microsoft has introduced many Windows patches to fix these errors.
Wrong. We can visit the upgrade website related to Windows or run Windows from the Start menu.
Update, so that we can get all kinds of OS patches, strengthen system security and get the latest.
Tools (such as the latest version of the media player and IE browser). We can do it every three hours.
Check whether there is a new upgrade program, and choose a useful download after 6 months. During the upgrade process
You'd better back up some important data before.
Registry tampering countermeasures: don't move if you don't understand!
When Windows is installed, it creates an important file to track a lot of hardware.
And many system settings. This file is the registry. Add and remove software
When installing hardware, Windows will also automatically modify the registry. For most people, registration
The contents in the form are difficult to understand. Don't touch it if you don't know it clearly. No.
Then there is a problem. Windows may not start.
Countermeasures for deleting files by mistake: sometimes you have to "no" Usually, when deleting a file, the system will
Give a hint, for ordinary files (such as documents, pictures, etc. ), you can press OK directly, and then
Those important files, such as EXE, DLL files or program components, have been deleted.
Please think about it before, and it is also under the Windows system folder.
Very important files should be carefully deleted. But Windows has a recycle bin, so if you empty it,
Many files will be permanently deleted. So don't empty it often.
(3) System crash caused by hardware If there is no problem, we rarely move the chassis.
The various components of. But the expansion card is loose, the data line is worn, the system is overheated and so on.
Failure will make our computer unable to work. In fact, we don't need professionals, we can also take it ourselves.
Take some measures to prevent it.
"Drowning" Countermeasures: Please drink water nearby. The keyboard is sensitive to water (relatively high
Class waterproof keyboard that is another matter). If water spills on the machine, please turn off the power immediately.
And wipe the water that seeps into the equipment clean. It's best not to drink water next to the PC, even the best.
Is to cover the machine with something.
Countermeasures for overheating loss: ventilation is very important, and the heat generated by the monitor during operation is very large.
It is very important to keep good ventilation. Don't put books and other things on the monitor.
If the monitor is overheated, it will lead to color and image distortion and even shorten the life of the monitor.
Countermeasures for improper action: avoid vibration. The PC is on the table, not the notebook, so don't be frequent.
Walk around. Because in the process of moving, if you get a lot of vibration, it will often make the CPU inside the machine,
RAM and expansion card are loose, resulting in poor contact. If you want to transfer this machine, you'd better use it
Cushion box packaging, display placed downward, can reduce its center of gravity, reduce shaking.
Countermeasures for electronic damage: everything is to "stabilize" the computer, and don't consume large power at the same time as the air conditioner.
Some household appliances are turned on at the same time, because the surge caused by excessive current will bring the power cord and the computer.
What's more, it will decompose the electronic components in the computer, so that the whole system will really collapse.
It's over. Therefore, if conditions permit, voltage regulators can be configured, if there are frequent power outages.
You can also use UPS.
Smoke killer countermeasure: keep the air clean. Smoking is harmful to health. Similarly, smoke will enter.
Drive, and has a certain influence on the read-write head, resulting in errors in reading and writing data, usually reading
The read-write head is suspended on the CD, so if there are some smoke particles on the read-write head, you can
Will cause contact friction with the optical disc, which will lead to reading and writing errors. Smoking also affects CDs and DVDs.
The reading error of optical disc is caused by the quality of optical disc. Therefore, it is best not to smoke near the computer.
CD-ROM lacks "caring" countermeasures: avoid CD-ROM pollution and scratch fingerprints, dust and dirt.
Moreover, scratches will lead to disk reading errors, and the scratches are too deep to read the disk. It is best to put the CD in the CD bag.
Don't touch the surface of the plate when you take it. And don't put labels on CDs. Today's optical drive speed
They are all very fast, so even a small label will cause the reading disk to be unbalanced, and the general optical drive.
When reading a CD, it will make a strange squeak, which means that the CD can't keep balance. Although this is very important to the optical drive itself
There is no effect, but it will lead to disk reading errors. If you want to mark, you can keep it straight with a watercolor pen.
