经常就是自己关闭了mysql 需要开启服务器来启动mysql

你好，电脑每隔一段时间就自动重启，可能有以下原因：
1,系统太薄弱,没有对系统漏洞及时打补丁
2,误操作删除了重要系统文件或非法关机造成系统文件丢失
3,感染了病毒,(安装杀毒软件,系统严重损坏的话要重装)
4,电源有问题,(电压不稳定或机箱电源损坏,电源60%的情况是风扇烧毁)
5,是否有超频,有的话去掉超频
6,主板电池击穿(更换电池)
7,CPU的温度过高(更换损坏的CPU风扇或其他)
8,机箱内积尘过多吸潮后导致高温静电打火(打开机箱除尘)
9,显卡或网卡的金手指接触不良(拔下从新插牢,有铜绿的话可以用橡皮擦掉)
希望能帮助到您。\(^o^)/~
