It's no big deal that the computer crashed. If it crashes frequently, there is something wrong with your machine. The cause of computer crash

1. System and virus problems: You can reinstall or restore a new system and check for viruses.

2, setup problem: BIOS settings, you first set the BIOS to the default settings. Right-click my computer properties, find the "If there is a problem, restart" option and check it. The system settings are also confirmed to be ok.

3, heat dissipation problem, if the heat dissipation performance is not good, it may automatically restart. But that's unlikely.

4. Power supply problem: the phenomenon of insufficient power supply may also lead to restart. You can try to change someone else's power supply.

5, software problems: some software itself has problems, you can change the software.

6. Driver problem: No driver is installed or the correct driver is not installed. Uninstall and reinstall.

I think your questions are about 2 and 6. Check it yourself.

2. What if the computer doesn't respond?

1) What do you do on your computer when your computer screen gets stuck or crashes? Can you tell me something? I will give you a more accurate answer according to what you said.

Please elaborate on your computer performance before the screen stuck or crashed, and your operation, which may be the cause of the screen stuck or crashed. Ask me if you have any questions (I will answer you again according to the information you provided).

Generally, the screen jam or crash is caused by your incorrect operation. Remember not to do anything that may cause a screen jam or crash. Don't operate the computer at full load, that is, when playing games, watching videos, downloading and watching web pages, it is most likely to restart, crash and blue screen when doing other operations, so don't operate other things when playing games, watching videos, downloading and watching web pages.

No matter what you are doing, as long as there are signs of card, stop what you are doing and quit the test. If it's still like this, don't play or watch.

In terms of hardware, if the memory stick is small, add the memory stick. The temperature of CPU and other hardware is too high, and the hard disk is broken, all of which are caused by improper hardware.

2) If it is related to hardware, one is that your memory is low, the temperature of hardware such as CPU is high-definition, and there is something wrong with the hard disk. In terms of software, it is necessary to uninstall what was downloaded before the accident, download Win cleaning assistant to kill Trojans, restore the system or reinstall it, and do not run at full capacity if there is any.

3. What if the computer doesn't respond?

Do a few things:

1): Open my computer-right click on the local disk c "-Properties-click Disk Cleanup-check the recycle bin, old data and IE temporary files. . "Wait-click OK-click Yes.

2): Click Clean-Click Yes-Click OK-Click Yes-Right-click the local disk C"-Properties-Other options-System Restore in the box that opens my computer.

3): Right-click on My Computer-Properties-System Restore-select C- Settings-Move the slider to the left to the minimum, or close-Apply-OK.

4): Set the correct virtual memory: right-click my computer-Properties-Advanced-Performance box, click' Settings' card-click' Advanced'-click' Virtual Memory' box to listen to' Change'-select' Custom Size'.

Generally, the maximum value is 1.5~~2 times of the initial value.

How to determine the maximum value? Open Task Manager-click "Performance". Look at the' peak' in the' approved usage' box at the bottom left, and its calculation unit in the task manager is K. 1024K= 1MB. Calculated in MB, this is the maximum value. Open it several times and see the highest value several times. For example, my peak value is 650328K. Then the maximum value of my computer is 650328K/1024=636MBM, and the initial value is 3 18MB. Fill it out and click Change.

5): It is also the most important step. Upgrade antivirus software and Trojan Horse Killing, restart the machine, press F8 to enter safe mode, and scan and kill in safe mode. This step is best done at regular intervals. And regularly upgrade antivirus software, firewalls and trojans.

Operate step 1, 2, 5 every three to five days.

4. How to solve the problem that the computer screen is stuck and there is no response?

In this case, hold down CTRL+ART+DEL, choose to start the task manager, see which applications are not responding, and just close them directly. If there is no response, press the restart button on the host.

If there is no restart button on the chassis, press and hold the power button for a few seconds, and it will automatically shut down. Then try to open it again.

The computer screen is stuck and cannot be operated. This is called a crash. There are two kinds of collapse: real death and suspended animation. You can press the CAPS LOOK key on the keyboard. If the corresponding indicator light can react normally, it is suspended animation, otherwise it is really dead. Fake death is usually caused by software, mainly because there is too much software running in the background, or a program crashes or stops responding. At this time, you may have to wait patiently for a while, and when the computer finishes processing these background programs, it may "come back to life". You can press CTRL+ALT+DEL to call up the task manager, find out the programs that are unresponsive or occupy too much CPU and memory, end them, and let the computer work normally again.

The real death is mainly caused by hardware and software. Generally speaking, if the computer is not well cooled, it may overheat and crash after running large software. If the hard disk has a bad track and the memory is faulty, it will also crash. Moreover, the background program takes up a lot of hardware resources, which leads to the computer not running normally and ending its process. For example, a large number of worms infect computers, which can also cause computers to be overwhelmed or overheat and crash. Use software (such as 360 hardware master) to monitor the hardware temperature in real time to see if the CPU temperature is too high.

If it is not caused by high temperature, check the motherboard and graphics card to see if there is something wrong with the capacitor, which leads to the crash. This is the phenomenon of computer suspended animation, and the most common problem is software, followed by hardware conflict, too much dust, poor contact and so on. The main problem of software is that there are too many open programs, which leads to the serious consumption of system resources and the unresponsiveness of programs, while there are not many open programs, so there is a great possibility of too much dust. It is suggested that the landlord go to a nearby repair shop for dust removal, and then add some silica gel and lubricating oil.

My computer is stuck, but nothing happens when I press it. What should I do?

Restart the computer, press F8, safe mode, last correct configuration, enter, enter! Software conflict and incompatibility: redundant similar software installation! Computer overclocking or installing too much software, the system memory is insufficient! Tencent computer housekeeper, software management uninstall, and then vigorously clean up! Or: start the menu, programs, and find extra software to uninstall! For example: players are duplicated or similar, antivirus, browsers, games, input methods, download tools, there are similar redundancy, uninstall redundancy, only one is left! The computer system has stubborn virus and Trojan horse or worm interference, or lost system files! Kill the whole thing with Tencent computer housekeeper, and then restart the computer! After booting, in the file recovery area, click: suspicious startup items and trojans to completely delete files! After testing, the hardware in Tencent's computer housekeeper toolbox is re-driven.

6. What if the computer can be turned on but can't be used?

Click the icon on the computer desktop, and there is no response. This situation generally has the following situations, and the solutions are as follows:

1. If it is turned on, don't operate it immediately after it is turned on, because the background is loading programs when the computer is turned on, and it is very stuck at this time. Please wait for the operation. This is normal. If it takes too long, see the following methods.

If such problems are caused by software conflicts, improper drivers or system problems, you can restore the system or not reinstall the operating system. Don't install software, patches, drivers, turn it on and see if there are any problems. If you don't install drivers, patches and software step by step, don't install them (if it is a hardware problem, please repair them, such as hard disk).

2. In addition, it is also related to improper operation before shutdown, such as playing games, watching videos, operating large files, using the computer for a long time, or downloading inappropriate things, and the failure will not happen for no reason.

3, if it is caused by improper operation, as long as you pay attention to your computer is not a card, blue screen, suddenly shut down, boot will not be like this.

Note: If the computer itself fails, it can be sent to the nearest maintenance point for repair.

8. What should I do if the computer boot screen doesn't respond?

Computer screen card reason:

1. Virus Trojans like to hijack thousands of system load points because of "why the computer screen is stuck". Kidnapping the normal files of the system caused the computer screen to get stuck.

2. There are too many startup items, and general programs can be closed except antivirus software and input method, so there are unnecessary services and planned tasks. Jinshanwei's system optimization can automatically help you with one-click optimization without manual operation.

There is too much rubbish in the computer system and a useless registry. System garbage includes the following contents

(1) (1) Window temporary directory, which stores all temporary files generated by the system and applications.

⑵ The window update patch directory is the place to store the patch installation package downloaded by the update program that comes with the system.

(3) The browser cache directory is the place where you can store the web pages accessed by the browser.

4. There are too many fragments on the computer hard disk.

Computer card screen solution:

First, check whether your computer is infected with a virus.

1. Enter the main interface of Jinshan Guardian to kill Trojans.

2. Then click Quick Scan.

2. Remove computer junk files

1. Open the main interface of Kingsguard and click the "Garbage Cleaning" tab to clean up the garbage files, traces and registry.

2. Then click "Large File Management" to delete or transfer large files according to the scanning results. If you don't know which large files can be migrated, click here.

3. Click the "System Slimming" tab. Over time, there are more and more dispensable files in the system disk, which not only takes up disk space, but also affects system performance. Manual cleaning is inconvenient and unsafe, which can intelligently detect and clean unnecessary files in the system disk and release disk space.

3. The system optimizes the useless services and startup items of the system and closes the process that causes the computer screen to get stuck.

1. Enter the main interface of jinshanwei and enter the system optimization.

2. Then click one-click optimization.

3. Finally, select the "System Acceleration" button, and then use "One Button Acceleration" to close the process that causes the computer screen to get stuck.

Solve the problem in my way. If not, ask me again.

9. Why is the computer always stuck, unresponsive and needs to be restarted every time?

1) If you are talking about the boot crash, is it related to your improper operation before shutting down? For example: playing games, watching videos, operating big things, and using computers for a long time? Or download inappropriate things, or delete system files, or shut down. Failure won't happen for no reason, will it?

One is to put it away for half a day or one day, and sometimes it will recover itself. The other is to reinstall the system.

As long as you pay attention to your computer, it won't be like this when you turn it on.

Ask me any questions.

2) If this is the case during normal operation.

What do you do on your computer when your computer screen is stuck or crashes? Can you tell me something? I will give you a more accurate answer according to what you said.

Please elaborate on your computer performance before the screen stuck or crashed, and your operation, which may be the cause of the screen stuck or crashed. Ask me if you have any questions (I will answer you again according to the information you provided).

Generally, the screen jam or crash is caused by your incorrect operation. Remember not to do anything that may cause a screen jam or crash. Don't operate the computer at full load, that is, when playing games, watching videos, downloading and watching web pages, it is most likely to restart, crash and blue screen when doing other operations, so don't operate other things when playing games, watching videos, downloading and watching web pages.

In terms of hardware, if the memory stick is small, add the memory stick. The temperature of CPU and other hardware is too high, and the hard disk is broken, all of which are caused by improper hardware.

3) If it is related to hardware, one is that your memory is low, the temperature of hardware such as CPU is high-definition, and there is something wrong with the hard disk. On the soft side, uninstall what was downloaded before the accident, download Win cleaning assistant to kill Trojans, restore the system or reinstall it, and don't run at full capacity if there is one.

Win78 can basically run 4G memory, XP is 2G memory, and it is best to double it. If you don't use this number, it is recommended to add more memory (this is a practical number, not a theoretical number).
