1.把主板的电池拿出来，反扣，放电。目的：是BIOS的设置恢复默认值，排除BIOS的散热预设自动重启或关机现象。
2.清扫机箱内的灰尘，排除因为灰尘过多导致主板短路或散热不良。
3.你看看是不是CPU导热硅脂干了，硅脂是用来提高散热能力的，如果没有硅脂可能会导致热量散发不出去，机器自动关机。一包几元钱，注：如果导热硅脂太多太厚，就会在接触面中间成了一张膜，反而阻碍了金属的直接接触，比不涂导热硅脂更差。
4.你可以考虑一下是不是风扇大小或风扇能力对于高端配置的电脑来说已经力不从心？先从风扇的大小考虑（越大越好），再考虑功率（越大越好），还有厂家。
5.剩下的就是其他客观原因了，例如室内温度高，开机的时候长时间运行大型程序（游戏），机箱散热不好，中毒CPU使用率经常100％等等。推荐在百度里搜索Everest，把这个软件下载下来（不用安装的）点计算机—>传感器—>就可以看到硬盘温度，CPU温度，风扇转速等等了。
————了解计算机引导型病毒的传染过程
在系统运行时，病毒通过病毒载体即系统的外存储器进入系统的内存储器，常驻内存。该病毒在系统内存中监视系统的运行，当它发现有攻击的目标存在并满足条件时，便从内存中将自身存入被攻击的目标，从而将病毒进行传播。 而病毒利用系统INT 13H读写磁盘的中断又将其写入系统的外存储器软盘或硬盘中，再感染其他系统。
可执行文件感染病毒后又怎样感染新的可执行文件
可执行文件.COM或.EXE感染上了病毒，例如黑色星期五病毒，它驻入内存的条件是在执行被传染的文件时进入内存的。
一旦进入内存，便开始监视系统的运行。当它发现被传染的目标时，进行如下###作：
（1）首先对运行的可执行文件特定地址的标识位信息进行判断是否已感染了病毒；
（2）当条件满足，利用INT 13H将病毒链接到可执行文件的首部或尾部或中间，并存大磁盘中；
（3）完成传染后，继续监视系统的运行，试图寻找新的攻击目标。

The system is running, the virus vector that is outside the system memory into the system, memory, permanent memory. Of the virus in the system memory in the surveillance system of operation, when it found that the target of attacks there and meet the conditions, Piancong memory will be deposited into their own targets, which will spread the virus. The virus used to read and write disk system INT 13H of the interruption will write the system memory, hard disk or floppy disk, and then infect other systems.
Executable file and then how the virus infected the new executable file
Executable file. COM or. EXE infected with the virus, such as Black Friday viruses, it's the memory of the conditions in the implementation of the document was transmitted into the memory.
Once in memory, started the operation of surveillance systems. When it was found that the transmission of objective, as follows # # # for:
(1) first run of the executable files of the logo at a particular address to determine whether the information has been infected with the virus;
(2) when conditions meet, INT 13H of the virus linked to an executable file the first or the middle or the tail, both large disk;
(3) after completion of transmission, continue to monitor the operating system, trying to find new targets.
