It should be caused by the incompatibility between the vulnerability and the computer system or certain application software, and the compatibility issues between the system version or the installed software and the newly released patches from Microsoft. Press F8 at the startup screen to enter safe mode and open the Tencent computer Butler, try to fix the bug.
And Tencent Computer Manager can also delete fixed vulnerabilities. That is to say, if your computer conflicts with the latest vulnerabilities, you can just delete them in "Installed" and there will be no problem. Use Tencent Computer Manager to fix vulnerabilities. Tencent Computer Manager intelligently filters patches and will not install unused patches. Steps: Open Tencent Computer Manager---Patch Vulnerabilities---Scan Vulnerabilities--One-click Repair System Vulnerabilities refer to defects in the logical design of application software or operating system software or errors generated during writing. This defect or error can It is used by criminals or computer hackers to attack or control the entire computer by implanting Trojans, viruses, etc., thereby stealing important data and information from your computer, or even destroying your system.
Of course, it may not be caused by bug fixes, because it may also be a hardware failure. There are many reasons for a black screen on the computer. Common ones include: poor contact of the display data cable; no power supply to the motherboard; poor contact of the graphics card; or poor contact of the CPU and Overheating; poor contact of the memory module; poor power supply performance; the machine is infected with the CIH virus and the BIOS is destructively refreshed.
Maybe your computer itself already has hidden dangers, and this shutdown or restart just triggered the failure.
You can first rule out whether there is a problem with the monitor itself and whether the wiring is secure. Just connect the monitor to another computer and try it, because you said there is sound when turning on the computer. But if there is a sound when turning on the phone, what kind of sound is it? Normal startup music, or other sounds from the speakers?
If it’s the latter, you can judge where the problem may be based on the characteristics of the sound. For example, a sound that is one long and two short means that there may be a problem with the graphics card.
The motherboard is an indispensable part of the computer. It is the center that integrates various parts and connects them together. Sometimes some common problems will be found during computer motherboard repair. Here we will learn about the common faults and solutions to computer motherboard repair.
Computer motherboard repair Fault 1: No display when starting up
1. There is no display when turning on the computer. The first thing to check is the BIOS. Important hardware data is stored in the motherboard's BIOS. At the same time, the BIOS is also a relatively fragile part of the motherboard and is easily damaged. Once damaged, the system will not be able to run. Maintenance failures of such computer motherboards are usually caused by the CIH virus in the motherboard BIOS. Caused by damage. Generally, all data in the hard disk will be lost after the BIOS is damaged by a virus. Therefore, you can determine whether the BIOS is damaged by checking whether the hard disk data is intact. If the hard disk data is intact, then consider other reasons that may cause the computer motherboard failure. .
1. Because there is a problem with the motherboard expansion slot or expansion card, the motherboard does not respond and has no display after plugging in an expansion card such as a sound card.
2. If the CPU frequency set in the CMOS of the jumper-free motherboard is incorrect, it may also cause a no-display failure. This can be solved by clearing the CMOS. The jumper to clear CMOS is usually near the lithium battery on the motherboard. Its default position is generally 1 and 2 short circuit. Just change it to 2 and 3 short circuit in a few seconds to solve the problem. For old motherboards in the past, go to computer motherboard repair If you can't find the jumper, just remove the battery, wait for the boot display to enter the CMOS settings, then shut down, and put the battery up to achieve the purpose of CMOS discharge.
3. During computer motherboard repair, the motherboard cannot recognize the memory, the memory is damaged, or the memory does not match, which will also cause no display at boot. Some motherboards are picky, and once you plug in memory that the motherboard doesn't recognize, the motherboard won't boot. Some motherboards won't display anything. Of course, sometimes in order to expand memory to improve system performance, plugging in different brands and types of memory will also cause such failures.
4. For computer motherboard repairs where the BIOS is damaged, you can plug in the ISA graphics card to see if there is a display. If there is no startup screen, you can make a floppy disk that automatically updates the BIOS and refresh the BIOS. Some motherboards have their BIOS damaged. , the floppy drive does not work at all, so the reliable method is to use a code writer to write the BIOS update file into the BIOS. It is safer to find a computer dealer that provides this service.
Computer motherboard repair fault 2: CMOS settings cannot be saved
This kind of fault is caused by insufficient voltage of the motherboard battery. It can be replaced. Some motherboard batteries cannot solve the problem after replacement. You can find a professional to repair it. , motherboard CMOS jumper problem, sometimes because the CMOS jumper on the motherboard is mistakenly set to the clear option, or set to an external battery, the CMOS data cannot be saved. Therefore, when repairing computer motherboards, you should pay attention. If you need this information, you can refer to the above content for assistance. I hope this article can help you.
Visual inspection method
Visual inspection method is to visually observe circuits, components, etc.
Contact inspection method
Contact inspection method is when the ECU is in working condition, and the inspector uses direct contact to find the fault point. During the process of contact with the component to be inspected, the temperature is sensed through touch and the odor is sensed through smell to confirm whether there are any abnormal symptoms. This method is convenient, simple, practical and highly targeted, and can directly find the fault location, but it requires rich inspection experience to obtain accurate inspection results. In order to avoid causing new faults, during the inspection process, the ECU should be placed stably, and attention should be paid to keeping a safe distance between the circuit board or electronic components and other parts (especially the body chassis part) to avoid grounding of the lines and causing irreparable faults.
Fault Regeneration Method
Fault Regeneration Method is to consciously allow faults to reoccur, and strives to make the occurrence, development, and transformation process of faults slower, so as to provide sufficient observation opportunities, times, time and processes. During the observation process The factors that affect the fault can be discovered to find out the location and cause of the fault.
1) First soft and then hard, reinstall the operating system, do not install software, patches, drivers, etc., and see if there is still any problem when booting? If you are not installing drivers, patches, and software step by step, don't install anything that is inappropriate. Please note: If you install drivers, patches, software, etc. after restoring the system or reinstalling, be sure not to install the things that affected your accident, otherwise the restoration or reinstallation will be in vain.
2) Whether there are any problems with hardware, such as hard disk, memory, graphics card, motherboard, etc. If it is caused by hardware problems, it is recommended to have them checked.
3) In addition, is it related to your improper operation before shutting down? For example: playing games, watching videos, operating large things, using the computer for a long time caused by card? Or you downloaded something inappropriate, and the fault won't happen for no reason, right (if it's caused by this problem, just make sure your computer doesn't get stuck, have a blue screen, or suddenly shut down, and it won't be like this when you start it up)? If it is caused by 3, as long as you pay attention to your computer not to freeze, blue screen, or suddenly shut down, it will not be like this when you start it up.
4) If it is caused by answer 3 and the computer is stuck when starting up and running normally, please check the answers below. This is disk damage caused by illegal shutdown or other reasons. Please repair it (repair each disk or only repair C). The system's own disk repair method: The specific steps are as follows: Select the drive letter C in My Computer, right-click the mouse and select Properties. In the pop-up drive properties window, select "Tools → Start Checking" and select "Automatically Repair Files" System Error" and "Scan and recover bad sectors", and then click Start. The scan time will vary depending on the disk capacity and scan options (after following the above method, a box will pop up, click Yes, and it will automatically shut down After booting up to repair, Win78 selects the scheduled disk check button). If the fault persists, please restore the system or reinstall (it still doesn't work, format the hard disk, repartition and reinstall).
5) If you have any questions, please ask me.
