1. Self-check can pass, but it cannot enter the desktop. Is it an operating system or driver problem: (xyz58 19 Idea space-time)
Why can't the computer normally enter the desktop or crash the blue screen after repeated restarts? (xyz58 19 idea space-time)
In the case of virus removal, it is generally due to the installation of GHOST version or other modified versions of the operating system, because a large number of drivers that are not suitable for your hardware devices are integrated in advance, which leads to the system being unable to correctly identify and load the necessary hardware devices of the system. (xyz58 19 idea space-time)
Re-downloading and installing the operating system with the original image installation version can correct such errors. (xyz58 19 idea space-time)
If you don't want to reinstall, you can try to open F8, enter the safe mode to uninstall the incompatible drivers of hardware devices (that is, right-click the device in the device manager) > Properties > Presence > Digital Signature Program >: drivers of Microsoft Windows hardware compatible publishers), start the computer to automatically identify the hardware devices, reinstall the downloaded drivers (WHQL) that have passed the Microsoft digital signature authentication, and then restart the computer again to see if there are any improvements. (xyz58 19 idea space-time)
Then there are conflicts caused by software with duplicate functions in the system (for example, two or more software killers and firewalls are installed, and advertisements are blocked). (xyz58 19 idea space-time)
If it is confirmed that it is not a system or software problem, you need to test the hardware in the following order: first, memory is the most likely, then CPU, then hard disk, and finally graphics card. There will be basically no blue screen on the motherboard. (xyz58 19 idea space-time)
In addition, check whether the machine is overheated due to poor heat dissipation (if it is, it is necessary to install a stronger radiator, repaint thermal silicone grease and replace the high-power fan). (xyz58 19 idea space-time)
Check whether the top of the motherboard capacitor is convex (if convex, it must be replaced immediately). (xyz58 19 idea space-time)
Also check whether the output voltage is unstable due to insufficient power supply of the chassis (if it is, it must be replaced immediately) (xyz58 19 Idea space-time).
If the power-on self-test fails and you can't hear a "click", it must be a hardware failure. You need to make a preliminary judgment with the alarm sound of a small horn (buzzer) to narrow down the scope of hardware failure. Please refer to your motherboard manual for the specific meaning of the power-on alarm sound. (xyz58 19 idea space-time)
Friendly reminder: as long as the driver works, don't blindly pursue new ones. Otherwise, installing incompatible drivers will lead to unstable system operation, which often leads to blue screen of death phenomenon. (xyz58 19 Idea Space) It is recommended that you download the driver with Microsoft WHQL certification from the manufacturer of your specific hardware device or the driver's home. (xyz58 19 idea space-time)
Appendix Microsoft explained: The driver has not been digitally signed, which means that the driver has not passed the test of Microsoft's Windows Hardware Quality Laboratory (WHQL). Installing a driver without digital signature will lead to unstable operation of the operating system, resulting in blue screen of death phenomenon. You can get the WHQL-signed driver from the hardware manufacturer. (xyz58 19 idea space-time)
If you can't find it, download a driver wizard or driver life, and it will automatically help you find the corresponding driver in the networked state. (xyz58 19 idea space-time)
2. If the self-check fails, it must be a hardware failure: (xyz58 19 Idea Space-Time)
What should I do if I don't hear the "ticking" sound after starting the computer? (xyz58 19 idea space-time)
Hello, self-check after the computer is turned on. If you don't hear the ticking sound, it must be a hardware failure.
The following aspects should be checked and excluded: (xyz58 19 idea space-time)
1. The system time cannot be dBIOSplayed and saved correctly, which is caused by insufficient battery power on the motherboard. This kind of fault can be solved by replacing the new motherboard battery and pressing DEL key to reset the correct system time.
2. Check whether the motherboard capacitor bulges or leaks. If so, please go to a professional computer repair place to replace the motherboard capacitor. (xyz58 19 idea space-time)
3. Unplug the memory stick, wipe the golden finger with an eraser and plug it back in.
4. Reconnect all hardware and connecting wires firmly to avoid virtual connection.
5. Open the chassis and start it once to see if the fan is working normally. If it is not normal, please replace it.
6. Check whether the power supply of the chassis is insufficient, and replace it if there is a replacement power supply at hand.
7. Whether there is a hard disk failure will lead to a bad track, check the BIOS to see if you can identify the hard disk. (xyz58 19 idea space-time)
There is no signal on the display, so it is important to check the connection of the display part. The black screen or flower screen of the monitor may be the problem of the graphics card or the monitor itself.
9. According to the alarm sound of the small horn (buzzer) of the boot chassis combined with your specific BIOS preliminary judgment, so as to narrow the scope of the problem. Please refer to your motherboard manual for the specific meaning of alarm sound.
10. That's all I can think of for the time being, and I will check the other parts step by step even if I use substitution method or minimum loading method. (xyz58 19 idea space-time)
The computer can't enter the system without self-checking after it is turned on. What is the reason why the hard disk stays bright?
Replace CPU memory, graphics card, motherboard and hard disk in turn by replacement method to find out the faulty hardware. (xyz58 19 idea space-time)
1. First, check whether there is any problem with the hard disk settings and connecting cables. (xyz58 19 idea space-time)
2. Hang it on another host to see if the fault still exists, and determine whether it is the motherboard or the hard disk. (xyz58 19 idea space-time)
3. If there is something wrong with the motherboard, replace and check the data cable and power cable, check whether the CMOS settings are correct, and clean the gold fingers of the memory stick with an eraser. (xyz58 19 idea space-time)
According to what you said, there is probably something wrong with the hard disk. You'd better back up the hard disk data as soon as possible! Use another good hard disk to start the system, and quickly back up important data while the failed disk is still recognizable.
5. Possible problems with your hard disk: bad tracks, damaged firmware, aging head (used for a long time). There may be a bad road. You can use MHDD to detect bad tracks on the hard disk. If your data is very important, it is recommended to restore the data through professional institutions such as 5 1Recovery. After the data recovery is completed, if your hard disk is under warranty, it will be guaranteed. If the warranty period has expired, please use DiskGenius's function of detecting and repairing bad tracks of hard disk to repair the hard disk. It should be reminded that it is taboo to continue to try to power on when the fault is not good, which will aggravate the problem. (xyz58 19 idea space-time)
6. If it doesn't work, you can change the installation disk (non-GHOST version). It is recommended to reinstall the system with the original mirror installation version. (xyz58 19 idea space-time)
First, there is no display when starting the machine.
This kind of fault is generally caused by poor contact between the memory stick and the motherboard memory stick. Rubbing your golden finger back and forth with an eraser will solve the problem (don't use alcohol to clean it, etc.). ), and memory damage or motherboard memory slot problems can also lead to such failures.
When the computer is turned on, the host speaker will generally beep for a long time (for the award-winning Bios) because the memory module does not display the fault.
Second, the windows system is unstable and often produces illegal errors.
This kind of failure is generally caused by poor quality of memory chips or software reasons. If it is determined that it is a memory stick problem, there is only one way to replace it.
Third, the windows registry is often damaged for no reason, prompting users to recover.
This kind of fault is generally caused by poor quality of memory chips, which is difficult to repair. There is only one way to replace it.
Fourth, windows often automatically enters safe mode.
This kind of failure is generally caused by the incompatibility between the motherboard and the memory stick or the poor quality of the memory stick. It is very common to use PC 133 memory chips on some motherboards that do not support PC 133 memory chips. You can try to slow down the memory reading speed in CMOS settings to see if it can solve the problem. If not, the memory stick will have to be replaced.
Five, random collapse
This failure is generally due to the use of several different chips of memory chips. Because the speed of each memory chip is different, there is a time difference, which leads to the crash. This can be solved by reducing the memory speed in CMOS settings, otherwise only the same type of memory can be used. Another possibility is that memory chips are not compatible with the motherboard, which is generally rare. In addition, it is also possible that the computer crashes randomly due to poor contact between the memory module and the motherboard, which is more common.
Sixth, the system resources decrease after the memory increases.
This phenomenon is generally caused by incompatibility between motherboard and memory. It is very common to use PC 133 memory module on some motherboards that do not support PC 133 memory module. Even reinstalling the system will not solve the problem.
Seven, when windows starts, when loading the high-end memory file himem.sys, the system prompts that there is something wrong with some addresses.
This problem is generally caused by the damage of some chips of the memory stick, and the solution can be found in the following memory maintenance methods.
Eight, when running some software, there are often hints of insufficient memory.
This phenomenon is usually caused by insufficient remaining space on the system disk. You can delete some useless files and leave more space, generally not less than 2G.
Generally, there is poor hardware contact, hardware failure, or system file loss.
First, there is too much dust in the machine, and poor contact will cause a crash. Clean the chassis and plug in all connections securely. Among them, the first slot of memory (near CPU) cannot be empty, and the network card and sound card can exchange slots and change the data cable of hard disk.
Second, check the cooling, dust removal and oiling of CPU and graphics card, or replace the fan.
3. Remove the motherboard battery, connect the positive and negative poles of the motherboard battery slot with a screwdriver, and discharge the motherboard. If the battery is dead, please replace the motherboard battery with a new battery and set the BIOS to the factory default value.
4. Press F8, select the last correct configuration or safe mode, and see if you can enter the system. Unable to enter the system, reinstall the system.
5. If it still can't be started normally, there is something wrong with some hardware. In the absence of instrument testing, we have to check one by one through replacement. It's best to go to a friend's house with the same or similar machine configuration as yours and check them one by one by replacing them.
1. Try changing the memory, graphics card, hard disk and CPU.
2, boot into the BIOS, check the power supply, if the power supply is normal, that the motherboard is broken.
