电脑自动从启应该考虑的问题The question the computer should consider automatically is as follows:One, software1. The virusThe shock wave will also prompt the system to start automatically after 60 seconds.The Trojan horse controls everything from the far side of your computer, including the restart of your computer.Remove viruses, trojans, or reload systems.System file corruptionSystem files are destroyed, such as under Win2K KERNEL32. DLL, Win98 FONTS directory font when system runs under the basic file was damaged, the system will be unable to complete initialization at the start and forced to restart.Solution: override the installation or reinstall.Timed software or planned task software worksIf you set up rebooting or loading some work program in the "planning taskbar", the computer will start again when the timer comes. In this case, we can open the "start", check the inside have not familiar with the execution of the document or other work program regularly, check if the mask. Of course, we can also enter the "Msconfig" command in "run" to select the boot item.Two, hard bodiesThe power supply of the box is low, the dc output is not pure and the dynamic reaction is slow.Users or installers tend to ignore the power supply and adopt inexpensive power sources, so it is one of the biggest suspects to trigger automatic reboot.(1) the power supply output power is not enough, when running a large 3 d the CPU resources of the larger software such as games, when the CPU needs high-power power supply, power is not enough cause power protection and overload, stop the output. When the power is stopped, the load is reduced and the power supply starts again. Since the time for protection/recovery is short, the performance is automatic restart of the host.(2) dc power supply output is not pure, pure dc supply digital circuit requirements, when the dc output power harmonic content is too big, will lead to a digital circuit work error, performance is often freezes or restart.The CPU workload is dynamic and the requirements for the current are dynamic, and the dynamic response is fast. Some of the poor quality of the power supply will also cause frequent crashes or restart.(4) update equipment (high-end graphics CARDS/big hard disk, video card), increase equipment (after burners/hard disk), beyond the rated power output of original power supply, power will lead to frequent freezes or restart.Solution: switch to high quality power computer power.Poor memory stability, damage to wafers, or error settingThere is a relatively high chance that the memory problem will cause the system to restart the system.The memory heat stability is bad, turn on the normal work, when the memory body temperature rises to a certain temperature, cannot work normally, cause the death machine or restart.(2) memory chip minor damage, the boot can be self-checking (set quick start is not fully tested memory), also can enter the normal desktop for normal operation, when the I/O throughput run some big software (media playback, games, planar / 3 d drawing) will restart or crashing.Solution: change your memory.Setting the CAS value of the memory body too small can also cause memory instability, causing the system to restart automatically. It is usually best to use the default Settings of the BIOS, not to change it yourself.The CPU is too hot or cachedExcessive CPU temperature often causes a protective automatic restart. Basic reason for the high temperature is due to poor chassis, CPU heat dissipation, CPU cooling bad reasons are: the material of radiator thermal conductivity is low, the radiator and CPU interface between a foreign body (for quality assurance for more), fan speed is low, fan and radiator too much dust and so on. And P2 / P3 under the motherboard CPU temperature measuring probe is damaged or P4 CPU internal temperature measurement circuit, the BIOS on the motherboard has a BUG in a certain temperature under special conditions, protection Settings in the CMOS CPU temperature is too low, and so on can also cause protective restart.One, second level cache corruption inside the CPU is a common CPU failure. Light damage, or can be started, can enter the normal desktop for normal operation, when the I/O throughput run some big software (media playback, games, planar / 3 d drawing) will restart or crashing.Solution: mask the secondary cache (L2) or primary cache (L1) in the CMOS, or the CPU removal.Automatic reboot of AGP graphics card, PCI card (network card, cat)No standard or poor quality of the external card, causing the RESET signal error of the AGP/PCI bus to restart the system.There is also a case of the graphics card and the loose network card causing the system to restart.Automatically restart the interface, serial port, USB plug, and external devices that are not compatible(1) has a fault or incompatible, such as 。
