The self-check can pass, but you can't enter the desktop. It's the operating system or the driver: (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)
This error can be corrected by downloading and installing the operating system of the original image installation version and installing all drivers certified by Microsoft WHQL. (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)
The hardware problem of the notebook computer itself cannot be solved, so it is recommended to send it for after-sales service or professional maintenance. (xyz58 19 idea space-time)
If you don't want to reinstall, try to boot F8 into safe mode and uninstall incompatible drivers of hardware devices (that is, open Device Manager >; Right-click on each device) > properties > drivers > digital signature program >: there is no driver for "Microsoft Windows Hardware Compatible Publisher" in >; It is a driver that has not been digitally signed by Microsoft. If there is such a driver in the system, it will cause various problems. ) After turning on the computer to automatically identify hardware devices, reinstall the driver (WHQL) that you downloaded and has passed the Microsoft digital signature authentication, and then restart the computer again to see if there is any improvement. (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 and even 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. ★ Note★ Be sure to download and install the driver that has passed (WHQL) certification ★(xyz58 19 Idea space-time)

Causes and solutions of hardware blue screen;
1. The memory card has poor contact or compatibility. Unplug the memory card and try to put it back with an eraser. That's not enough. Swap the memory slot locations and try to insert it back. (xyz58 19 idea space-time)
2. The equipment is unstable due to poor board contact or quality problems. Turn off the machine and plug in all the hardware again to avoid virtual connection. (xyz58 19 idea space-time)
3. Hardware compatibility is poor, and non-brand assembly compatible machines are common. There is no good way to do this. After making it clear what is wrong, it should be changed (xyz58 19 concept time and space).
4. Poor heat dissipation of the computer causes the CPU or graphics card chip to crash due to high temperature, including some hardware design defects, such as some recalled graphics cards or computer parts. Thoroughly remove dust and strengthen the heat dissipation of the machine. If it doesn't work, replace the fan (radiator). (xyz58 19 idea space-time)
Causes and solutions of software blue screen;
1. Virus Trojans or malicious rogue programs cause the system to be destroyed. Use soft kill to thoroughly kill viruses. (xyz58 19 idea space-time)
2. The drivers installed in the computer are incompatible, and the computer will crash after running for a period of time. Uninstall the existing error driver, download and install the driver with Microsoft WHQL certification. (xyz58 19 idea space-time)
3. The serious conflict between software compatibility, software incompatibility and system conflict will lead to computer crash. If more than two softwares with similar functions are installed at the same time, only one is left, and the others are uninstalled and tried. (xyz58 19 idea space-time)
4. If the problem cannot be solved through step 1~3, it is recommended to reinstall the system with the original image installation version and update all drivers with Microsoft digital signature authentication. (xyz58 19 idea space-time)
5. Friends can download BlueScreenView and use it to read the file C:\Windows\minidump\*. Dmp, see which files are causing this blue screen error. (xyz58 19 idea space-time)
6. If you need further help, I hope Zhiyiou can provide specific blue screen codes. (xyz58 19 idea space-time)
The following six tricks basically get rid of the blue screen except hardware damage:
1. Use diskgenius >; Detect and repair hard disk bad tracks,
2. Wipe the gold fingers of the memory stick and graphics card and put them back.
3. Press F8-Select-"Use" to turn on the machine.
4. Using the Driver Wizard (Driver Life) will automatically help you update the appropriate driver.
[Note: Be sure to download and install the (WHQL) certified driver. (xyz58 19_ idea space)]
5. The computer is overheated with blue screen, and the radiator and fan are completely dusted, and then turned on after it is completely cooled, which will not change the radiator and fan.
6. Complete antivirus, and then restore or back up the system. If this is not possible, the original image installation version can be used to repair and install or completely reinstall.
