Why does the computer suddenly become unresponsive?

You defragment the disk first.

Now if you look at Task Manager, the memory usage must be more than the actual size of the physical memory. At this time, the computer uses a part of the space on the hard disk as memory, which is also called virtual memory. When the computer calls the data on the virtual memory (that is, the hard disk), because the read and write speed is slow, there will often be a "stuck" situation.

Therefore, increasing the memory module is the key to solving the problem. But you can also do some optimization on your computer, remove those good-looking themes, desktops, and minimize the waste of system resources ==, there are a lot of methods on the Internet, and I won't waste saliva anymore. There are also QQ, IE, and antivirus software are all big users of memory, and although 360 and nod32 are known for being lightweight, you can note that they will take up a lot of memory when upgrading the virus database.

In addition, it will be better to switch to a clean version of the system, install only the necessary software yourself, and don't run too many programs at the same time, so that the memory spike will be better. Try not to use IE to watch **, it's very memory-consuming. In fact, **** is similar to ** after looking at it, **** also needs to be ** after **, but **** is stored in the system as a temporary file.

Clause. 1. Computer unresponsiveness is actually a state of computer feigned death, many times because of their own memory occupation is too large, at this time we can use some third-party software to clean up, such as computer assistants and other brand optimization computer tools can be solved.

Clause. Second, when our machine is used, when any program does not respond, it is generally your computer disk that meets the very large situation, we can open [My Computer] to find the built-in disk cleanup, and then set up the disk cleanup, and you can recover it in a while.

Clause. 3. In addition, when our computer mouse arrow has always been a small circle, you can use the combined function keys [Ctrl]-[Alt]-[Del] to press it together, so that you can bring up the [Windows] task manager and then open the process, and select [End Process] in it.

Please click Enter a description.

Clause. Fourth, after the above operation is completed, the computer desktop and taskbar will disappear, you now need to click on the [Windows] task manager with the mouse, and then find the file, browse in the new task, find the system disk, generally C disk, now we can select [ at this time we open, click OK on it.

Please click Enter a description.

Clause. Fifth, there is another situation that our computer program does not have any response after opening, at this time you can call up the [Windows] task manager, and then click on the process, now we can select no corresponding program, click to end the process.

Clause. Sixth, after we turn on the computer, there is no image display, wait for a long time is also like this, then at this time we estimate that the computer is a virus, we should reinstall the system, if you choose antivirus, it is estimated that it is useless, because generally this situation is that the system has been completely destroyed.

Clause. 7. There are many cases where the computer does not respond, and sometimes it is your computer motherboard that is damaged. The motherboard is damaged by the fact that the computer does not move at all, and no matter how you adjust it, nothing happens.

At this time, we should go to the after-sales department as soon as possible and let the staff there repair it for you!

1. The CPU is overloaded, or it is not working properly. Check CPU and graphics card cooling, dust removal, oiling, or replace fans.

Second, the power supply voltage is unstable and the power supply is insufficient. Replace high-quality, high-power power supplies.

3. Clean and defragment disks frequently.

1. In the "My Computer" window, right-click the drive letter you want to clean up - "Properties" - "Clean Disk" - check the files you want to delete - OK - Yes.

2. Clear the temporary file, start-run-enter "%temp%"-OK.

3. Clean up the registry and junk files with Optimizer or Super Bunny.

4. Close some startup programs, start-run-msconfig---start, in addition to anti-virus software, input methods can be turned off in general.

5. Delete unused program software.

7. Reduce the burden of memory, and do not open too many programs. If you have too many documents open or too many programs running at the same time, you will not have enough memory to run other programs, so you should close the programs and windows you don't use at any time.

4. Upgrade the graphics card and network card driver, and change to a higher-grade graphics card.

Fifth, increase the physical memory, now the memory is generally at least 2G.

Method. 1. Forced shutdown.

This kind of problem is generally stuck, you can force it to shut down by pressing and holding the power button, and it can generally start normally, if not, restart and press F8, enter the safe mode and select the last correct configuration.

Method. Second, check the machine.

1. The CPU fan speed is too low. Check the CPU speed, if it is too low, you can replace it with a new CPU fan.

2. There is too much dust in the chassis. Clean the chassis regularly to prevent poor heat dissipation caused by excessive dust.

3. Poor heat dissipation of the north and south bridges of the motherboard. Check whether the heat generated by the north and south bridges of the motherboard is too large, and add a small fan if necessary.

4. There are too many programs running in the system. Close programs that are not in use for the time being to ease memory.

This may occur when the computer suddenly freezes.

There are many reasons why the computer will not turn on, it may be that the computer has been turned on for too long, causing the CPU and graphics card temperature to overheat, which makes the computer freeze.

It may also be that the software and system installed in the computer are incompatible, resulting in the computer crashing.

It may be that the cache settings are not reasonable, and the content in the hard disk is called to the buffer area to speed up the access, which is likely to cause a crash.

Viruses and Trojans can corrupt computer resources and system files when they run, which may cause the computer to crash.

The blue screen of death can also occur when the computer is underpowered.

Initialization files that are corrupted due to accidental deletion of system files can lead to computer crashes.

If the machine crashes and you can't turn it on, you can turn off the computer first, open the case, pull out the motherboard battery, and clean the memory and graphics card from dust. Check whether there is any damage to the components, whether there is obvious heat generation of the parts, and dissipate the heat.

When you click the power button, press the [F8] button immediately and do not move until the [Advanced Options] text appears, select [Latest Correct Configuration] and click Enter. Or enter [Safe Mode] to scan and kill the programs installed in the system and restart the computer. Or restore the system or reinstall the system in [Safe Mode].

Check whether the power plug of the monitor is plugged in, move the mouse or press the keyboard to see if the monitor is normal, the computer may have a black screen for energy saving mode, you can view and modify it in the BIOS settings.

If the above methods fail to restart the computer, it is recommended to seek professional help or send it for repair.

First of all, reinstall the system with the pure version of the system disk, all hardware drivers, all use the official website version, this configuration, has the best compatibility and stability.

If reinstalling the system doesn't solve the problem, it may be a hardware issue.

First of all, clean the gold finger of all boards, especially the gold finger of the graphics card and memory, to see if you can solve the problem. If not, the possibility of hardware failure cannot be ruled out, and it is recommended to send it to a repair shop for testing and maintenance.

The reason for this problem is either a software problem or a hardware problem, you can first click the numlock key of the keypad part of the keyboard, if the numlock indicator of the keyboard is turned on and off with the click, it is usually a software problem, you can restart the computer to try, if you can't solve it, you can reinstall the system, if you press the numlock key indicator light does not change, it is always on or off, which is usually a computer hardware failure, and it is necessary to check and replace the hardware to find the hardware in question.

This is a computer crash, usually due to insufficient running memory, or the slow running speed of the system, generally rebooting is OK.

I think there are two situations that will cause this phenomenon, one is that the computer crashes. In other words, you can only remove the actual function if you restart the computer. The second is that the computer automatically shuts down, and the phenomenon of plugging in a black screen, you can restart the computer or force the computer back to its original state.

When the computer is running, it suddenly disappears, and the reaction may be that the driver is incompatible. It is also possible that the data cable of the hard disk is not in good contact, the data cannot be read, or the hard disk is faulty. Or the memory module is in poor contact. It is also possible that the power supply is malfunctioning.

The computer is running, and suddenly there is no response. Problems with computer hardware and software can occur.

The software may be because of a virus, and reinstalling the system is the absolute way.

In terms of hardware, it may be due to a short circuit in the power supply. You can choose between hardware and software depending on your needs.

It's called a "crash". There are many reasons for the crash, software, hardware, viruses, etc. You can turn off the computer and restart it, if it still doesn't work, you need to check it according to the situation.

If you don't understand it, you can ask a friend to help, or ask a professional maintenance person to check and repair. FYI.

Back in the days of DOS, there were quite a few viruses that were able to automatically restart your computer. For whether it is a virus damage, we can use the latest version of antivirus software for antivirus, and viruses are generally found. Of course, there is also the possibility that someone maliciously hacked into your computer and placed a Trojan horse when you were surfing the Internet.

This allows them to control everything on your computer from a remote location, including getting your computer back up.

It is very normal for the computer to crash, in the case of normal startup, you can basically rule out hardware problems, the crash is the reason for the software, one is the computer in the virus, to kill the virus in time, if you can't completely kill the virus, it is recommended to reinstall the system. The second is the loss of operating system files, it can also be said that the patch installation is unsuccessful, and the missing files lead to a crash, it is recommended to repair the system files with the boot disk, and the system cannot be repaired and reinstalled.

If the computer suddenly does not respond during operation, it is "dead". Crashes are divided into fake crashes and real crashes. There are many reasons for the crash, such as poisoning, network speed can't keep up, computer resource exhaustion (CPU, memory overload), etc. It's best to be patient and wait a while.

The computer suddenly does not respond in operation, it should be a crash, if so, you can restart the host, it should be recoverable, most of the cases are, due to low configuration, caused by Caton.

That's a crash, CPU, graphics card, etc. heat dissipation is not good, open the host to see if the fan does not rotate or the speed is slow, if it is normal, it may be a system problem or a virus, check and kill the virus or directly rebuild the system!

It's possible that there is a problem with the hard drive.

Have you ever rebooted to try it? Generally, if it is a software problem, it will be OK after restarting it.

If the computer cannot be turned on normally after power failure, it is estimated that there is a problem with the hardware or system files. First, use the replacement method to troubleshoot the hardware problem (mainly check the motherboard and power supply). After the hardware is eliminated, it is a system problem, and it can only be solved by reinstalling the system.

It is an abnormal process, and there is also a phenomenon that the user clicks on the program, but the system is busy for a long time, and the program does not open, but pops up a prompt to end the process.

So what's going on the screen? It is better to be able to describe it in detail, for example, there is still information on the screen, but it freezes, then restart this situation to see.

Immediately after booting, press F8 to the advanced option to appear in the let go, select "the latest correct configuration" Enter to repair, not yet press F8 to enter the safe mode to restore the system or reinstall the system (if the reinstallation is also automatic repair, it is recommended to overhaul it, if you can enter the safe mode, it means that you have installed something inappropriate, and uninstall all the inappropriate things before the accident, or restore the system or reinstall).

The computer suddenly does not respond during operation, it may be stuck, it has not responded and cannot move the mouse, and the keyboard is invalid, which is a crash and needs to be restarted.

Restart it and take a look, if there is no way to start it then go to the computer store to see, after all, there are many reasons why the computer cannot run, such as the motherboard is burned, the monitor is broken, the circuit is short-circuited, or the power supply is useless, etc.

The computer is running. What's going on when there's a sudden lack of reaction? If the computer is in normal operation and suddenly does not respond, it must be a power outage, and the power supply is cut off, so there is no response.
