The notebook suddenly stuck, the mouse bought a reaction, and the screen was still on, so it could o

Loose graphics card, clean up the cheat! Usually your computer is not well maintained.

Some minor problems will occur one after another when the computer is used for a period of time, most of which are poor CPU heat dissipation, oxidation and loosening of memory modules caused by inattentive use and untimely maintenance. It is recommended to have a planned maintenance of the computer, including hardware, software, and usage habits.

The following Piao Piao summarizes the hard work and will not be modified. Please refrain from copying, please respect yourself! ）

1. Hardware. 1. Clean the monitor, keyboard, mouse, and the exterior of the chassis every half month.

2. Clean the inside of the chassis once a month, and use a hair dryer to blow the floating dust in the chassis.

3. Check the motherboard every three months, including a thorough cleaning of the motherboard, and clean the power fan. You can pull out all the onboard cards, wipe the gold fingers with erasers or RMB, and use a circuit board cleaning spray to clean the motherboard specifically (a sprayer like an exterminator available in the tech market, but with a smaller tank). Finally, all parts can be put back in place.

Be sure to pay attention to the various connections on the motherboard and make the identification in advance.

4. Clean the power supply fan once every six months (including the internal sanitation of the power box).

5. Reapply CPU silicon once a year. Be careful not to be too thick.

2. Software. 1. Patch system vulnerabilities at any time.

2. Close too many system startup items.

3. Reduce the software that is often associated with the network, such as: Storm Audio, Youku, Uusee, etc., as much as possible.

4. Carry out a comprehensive anti-virus once a week.

5. Junk file cleanup and disk cleanup once a week.

6. Disk defragmentation once a month.

7. Check the software once a month, resolutely remove the unnecessary or infrequently used software, and install it when you use it.

3. Good usage habits.

1. Turn on and off according to the specifications.

3. Don't install new software when you see it, 90% of it you have to uninstall - useless (or rarely used).

After the above is done, back up important files and software, reinstall the system, and install the 360 Security Guard Dual Engine Antivirus Suite. Optimize the startup item and pay attention to the hygiene of the machine.

You can try reinstalling the system.

Encountering this issue can be the cause of software malfunction: fatal virus infection or accidental deletion of missing files, file version mismatch, memory conflicts, abnormal shutdown, too many loaded programs on startup. It could also be the cause of hardware failure:

Whether or not the new hardware is plugged in, this issue that many people overlook, often leads to many inexplicable failures.

Solve the Sui Nationality Law.

1. The cause of the virus. Use PC Manager to disinfect the virus. 2. Memory reasons. Use an eraser to wipe the gold finger of the memory module and wipe off the oxide layer to ensure that the memory module is installed and running normally.

3. The chassis is not clean. The CPU fan has too much dust to run normally, causing the CPU temperature to be too high, so use a brush or hair dryer to clean up the dust on the inner wall of the case, the CPU fan, the graphics card fan, and the motherboard.

4. There is also a possibility that the system is unstable, at this time, you need to restart the computer and press F8 to enter the boot menu item, and select "Boot to the last correct balance family argument".

There is something wrong with the hard drive.

Special maintenance.

Dear users, there are many parts that cause the fault phenomenon of screen darkness, mainly: screen, backlight board, motherboard, graphics card, and the connection part between the backlight board and the screen.

Start by clearly showing how the section works:

The graphics card is responsible for sending the displayed information to the screen, and the screen line is the channel for information;

The backlight board is responsible for converting the direct current sent by the motherboard into alternating current, so as to use the high AC voltage to light up the backlight tube and provide the backlight. The principle is the same as that of a fluorescent tube for daily use, and the backlight plate is equivalent to the rectifier of the fluorescent lamp, but of course there is more than that.

After receiving the information signal sent by the graphics card, the screen can be directly displayed on the screen, and the backlight will light up the entire background, providing a light source and shooting into our eyes, so as to see the information.

There are some backlight boards that take the working mode of sending the backlight first and then sending the information signal, and there are some just the opposite, which is to send the information signal first and then send the backlight, the former is the so-called screen flash "failure", because it first sends the backlight and then sends the information, resulting in the white light flashing first, and then seeing the information, which causes the screen to flash, in fact, this is not a fault, this is a normal phenomenon, if the time gap between the signal and the backlight is controlled very short, this flicker will not be felt. In the latter way, the information is already displayed on the screen at the same time as the backlight is sent, and as soon as there is a backlight, the information can be seen immediately, so it feels like there is no flicker.

The following is an analysis of the various possible faulty parts:

Screen failure. This kind of failure is mainly caused by the bad backlight tube, and there are also some problems with the backlight tube's circuit, which leads to the failure to light the backlight normally, resulting in only displaying information and no backlight, that is, = screen dimming fault.

The backlight plate is faulty. When the backlight panel fails, it cannot provide the voltage or power of the lighting tube, and there is no backlight display, so the screen is dark.

Motherboard failure. If the motherboard with integrated graphics card is faulty (graphics card part), there will usually be a black screen or white screen failure, depending on whether the signal sent to the backlight is from the motherboard or look first, if it is a motherboard, and this part of the circuit is not faulty, there will be a white screen failure (at this time, the backlight is only lit up and there is no information display), if it is from the graphics card, unfortunately this part of the graphics card is also faulty, there will be a black screen failure.

There is another part that cannot be underestimated, that is, the connection part between the backlight plate and the screen, if the contact is poor, it will lead to the backlight plate to provide the lamp to work in the conditions are not available, resulting in the screen dimming failure. Finally, it is especially important to remind you to see if the sleep lever is pressed, because the sleep lever provides the function of turning off the backlight (because it is easy to cause this kind of failure if it is not installed well, and this is the reason why there is no "display" after the laptop screen is turned off).

The easiest way to distinguish whether the graphics card is faulty when the screen is dark is to connect an external monitor to see if there is a display, if there is, it is not a graphics card failure, otherwise it is a graphics card failure.

You can buy a telecom mobile phone in the Anhui Telecom online business hall, and the network hall will handle the contract machine to give a high phone bill, you can buy the machine at 0 yuan, which is very discounted, and at present, a number of brands of 4G models are fully listed!

1. Some viruses or other malignant programs will seriously occupy the CPU, making normal programs unable to be used normally, and the situation you mentioned will occur. It is recommended to check for viruses or reinstall the system.

2. The above situations will also occur in computer hardware, such as the motherboard capacitor is drummed, the memory module or graphics card is incompatible or there is a problem, the host power supply is problematic, the CPU temperature is too high, etc. It is recommended that the landlord check item by item, if you don't know much about hardware knowledge, you can take it to a professional place to test it.

It is obvious that the CUP temperature is too high, and the motherboard has automatic protection enabled. Your cup fan is broken and won't dissipate heat, replace it quickly, don't burn the cup or motherboard.

In fact, every time you force a computer to shut down, it may cause the following problems.

The first is that it is possible to burn out the hardware, generally when the computer is forced to shut down, the computer is originally running, in this case if the power is forced to fail, then it will cause particularly great damage to the hardware, if it is more serious, it will cause the hardware to burn out.

The second one may damage the disk, when the power is suddenly turned off, if the hard disk is running at high speed at this time, then it will cause it to fail to reset, then it may cause two results, either the file is lost, or the hard disk is damaged.

The third is that it can have a certain impact on the system,My ** should have seen such a prompt when I booted up,That is, the system is self-checking,Why is this happening? The main reason is that the last shutdown was a forced shutdown, if it has been a forced shutdown, then it will have a certain impact on the system, there may be a blue screen, black screen and the like, of course, it is not necessarily all like this, there may be a blue screen or black screen and other reasons, mainly because there is a problem with the hardware of the computer, so if there is a problem with the computer, you can find a professional to repair it.

The fourth is that it may lead to the loss of data, many people do not notice which disk is installed in the computer when storing files, or when installing software, because it will habitually default to be in the C disk, in this case, if you force the shutdown, it may lead to the loss of data files, no matter what you are doing, even if you feel that the computer is a little slow, you must not force the computer to restart, otherwise, it will also cause data loss.

Try it at boot, sometimes forced shutdown, which will cause the loss of system files and the system cannot be entered after booting.

The memory is large and the computer temperature is high. Poisoned, small space of C drive, bad sectors of hard disk may cause stuck.

No. However, as little as possible to force a shutdown, the performance of the computer can be reduced.

Reasons for computer screen jamming:

1.Virus Trojans lead to the "why is my computer stuck" reason, virus Trojans like to hijack thousands of system loading points. Kidnapping system normal files leads to computer screen jamming.

2.There are too many startup items at boot, and in addition to anti-virus software and input methods, general programmers can turn them off, and there are unnecessary services and scheduled tasks. Kingsoft Guard's system optimization can automatically help you optimize with one click, without your manual operation.

window temporary directory to store all temporary files generated by the system and applications.

The browser cache directory is where you use your browser to access web pages.

4.Your computer's hard drive is too fragmented.

Computer Stuck Screen Solution:

One. First of all, check if your computer is infected with a virus.

1. Enter the main interface of Kingsoft Guardian and enter [Kill Trojan].

2. Then click [Quick Scan].

Two. Zero out your computer's junk files.

1.Open the main interface of Kingsoft Guardian and click the "Junk Cleaner" tab to clean junk files, clean traces, and clean the registry.

2.Then click "Large File Management", delete or transfer the large file according to the results of the scan, if you are not sure which large files can be migrated, click here.

3.Click the "System**" tab, over time, there are more and more dispensable files in the system disk, which not only occupy disk space, but also affect system performance, manual cleaning is not convenient and unsafe, it can intelligently detect and clean up the dispensable files in the system disk, and free up disk space.

Three. The system optimizes the system useless services and boot startup items, and closes the processes that cause the computer to freeze.

1. Enter the main interface of Kingsoft Guardian and enter [System Optimization].

2. Then click [One-click optimization].

3.Finally, select the "System Acceleration" button, then use "One-Click Acceleration" and close the process that is causing your computer to freeze"

...It should be that the power is not automatically turned off. I just cut off the power to the motherboard.,,I should be able to wait a while.。

To add: then it is possible that you did not turn off completely, press and hold the power button for 5 seconds to see.

Fn+F2 try, you might just turn the screen off.

The symptoms of sudden crash may be that the computer has poor heat dissipation. Disassemble the chassis and clean the CPU fan.

At that time, the memory usage was estimated to be 100%, and you can sort out the fragments of the C drive, if the computer memory is small, you can consider adding a memory module to expand the memory. You can also unplug the memory module and use the eraser to erase the gold finger, if it is two memory sticks, you can swap the position to try.

Computer protection software, anti-virus software, etc., are not installed too much, such as Kingsoft Antivirus and 360 Guardian installed at the same time. In this case, the excess protection software is uninstalled. At the same time, clean up the software that you don't use.

If the hard disk is damaged, you can install a diskgenius software, which is a partition software, and try to find and repair the bad sectors.

Word can be set with an auto-save function, Tools - Options - Save.

I've had it too, but not often.
