What is the reason why the computer crashes when it is turned on?

Hardware failure: Hardware failure may cause the system to fail. Check whether the hardware connection is loose and make sure that all hardware parts (such as memory sticks, hard disks, graphics cards, etc.) are working normally. Software conflicts: Some software may conflict with the system or other software, causing the system to cash.

Memory problem: Memory problem may cause the computer to crash after power-on. Try to use memory diagnostic tools (such as Memtest86) to check whether there is a problem with the memory. Heat dissipation problems: Heat dissipation problems may cause the computer to overheat, which will lead to a crash.

Too little spare space on the hard disk or too many disk fragments will also lead to "dead" failure. Because some large applications require a large amount of memory to run, if the physical memory is insufficient, you need to use the virtual on the hard disk.Memory, if the remaining space of the hard disk is too small at this time, it may cause a dead phenomenon.

First of all, hardware problems may be a major reason for the computer startup. Hardware failures may include memory problems, hard disk failures, power supply problems or other component damage. For example, if the memory module is damaged, the operating system cannot be loaded properly and causes a dead death.

Defects of application software: If you run this kind of bug software, it may cause the system to die or fail to start normally. In this case, you should find the latest version of the software or simply uninstall it. Virus infection: Virus Trojan horses, etc. can cause a sharp decline in computer efficiency, resulting in frequent dead downs.

What should I do if the computer crashes after it is turned on?

Defects of application software: If you run this kind of bug software, it may cause the system to die or fail to start normally. In this case, you should find the latest version of the software or simply uninstall it. Virus infection: Virus Trojan horses, etc. can cause a sharp decline in computer efficiency, resulting in frequent dead downs.

Restart the computer. If you can enter the system normally, it means that the last abnormality was just an occasional program or system operation error, which is irrelevant.

HKEY_CLASSES_ROOTLnkfile subkey branch, in this subkey branch, find the key value name IsShortcut, whose type is REG_SZ, delete this value to remove the arrow on the shortcut icon.

If the computer crashes and cannot be started after the CPU overclocking or upgrade, it may be due to the CPU overclocking or upgrade. Just restore the CPU frequency to normal frequency or restore it to the state before the upgrade.

Why did my computer crash when I entered the system, just when the XP reading interface.

Poor heat dissipation: If the monitor, power supply and CPU work too long, it will cause a dead time, dust the fan and oil it. Dust killer, poor contact: too much dust in the machine, poor contact will cause dead machine failure. Clean the chassis regularly and plug in all connections tightly.

The software is incompatible. The newly installed software is incompatible with the system, resulting in a dead system as soon as it enters. Solution: Press F8 to enter the safe mode, delete the newly installed software 2, overclocking Excessive overclocking will also cause the inability to enter the system. Solution: Reset the BIOS settings.

When turning off the computer, do not use the power button in the chassis directly, becauseDirect use of the power button will cause the loss of files, which will not be able to start normally next time, resulting in a system failure.

First of all, determine the situation before the computer fails. If the computer crashes after moving, it may be that the computer is greatly shaken in the process of moving, causing the internal parts of the computer to be loose and poor contact, resulting in dead. Open the chassis and re-tighten the memory, graphics card and other devices.

The computer freezes when it is turned on, and the screen freezes. What should I do?

1. If there is still a dead machine, the integrated block video memory chip of the memory and graphics card should be re-welded. It can be solved.

2. The solution to the frozen screen of the computer: We canTo see if it is a crash problem caused by a virus in your own computer, we can use anti-virus software to carry out anti-virus operations on the computer.

3. Caused by virus Trojans, the destruction of system files by virus Trojans often causes the computer to crash. Solution: Use anti-virus software to detect and kill. The system file is damaged. If the important running files of the operating system are lost or damaged, such as some dynamic link library files, it will lead to sudden jamming.

Causes and solutions for computer startup

1. The chassis is too dusty, and the short circuit causes abnormal computer. The computer is too old. The computer is too old, and the mainboard capacitor is aging, causing the computer to crash. If the hard disk appears a ring channel, the hard disk will also cause the computer to crash.

2. Hardware aspect: poor board contact or quality problems cause unstable operation of the equipment. Poor computer heat dissipation causes the CPU or graphics card chip to crash due to excessive temperature, including hardware design defects, such as some recalled graphics cards or computer components software problems software aspects: 1 user is remotely Trojan horse control, everything on the computer is in the hands of hackers.

3. Excessive overclocking will cause the display to not light up or cry down after entering the system, which will cause the CPU to burn out in serious cases. External devices are damaged, printers, recorders, scanners and other external devices are damaged, but plug-and-play technology allows the system to still detect these devices at startup, resulting in a dead down.

4. Computer poisoning, attacked by viruses or Trojan horses, it is easy to crash; antivirus or reinstall the system to solve the problem.Too much software is installed in the computer system; due to low computer configuration, installing too much software will cause the computer to crash; deleting useless software can solve the problem.

5. This article will introduce the causes and solutions of computer crashes to help you better troubleshoot. Displays, power supplies and CPUs with poor heat dissipation generate a lot of heat at work, so it is very important to maintain good ventilation. Too long working time will also cause the power supply or monitor to dissipate well and cause the computer to crash.
