在处理电脑自动更新时，看到一篇这样的文章，里面讲到这样一个方法： “把系统时间调整到2051年，然后更改一下更新日期2051，之后再把系统时间调回正常时间。” 感觉是个奇怪的思路，于是就尝试了一下，结果出问题了。 ························································································································································································ 现象： 当我把时间调整到2051年后，电脑开始变得卡顿，鼠标点击一直有转圈的卡顿，电脑风扇也在急速飙升。 直接长按电源强制关机了。 开机之后电脑桌面就在一直闪屏，鼠标无法操作，按键大部分没有反应，能用的只有“ctrl+alt+.”调出任务管理器。 电脑风扇一直在高速运转，cpu直接飙满100。 ························································································································································································ 现象视频链接： 链接：https://pan.baidu.com/s/1bCOFwdGlFaNxtq58OaVbxA 提取码：2l38 –来自百度网盘超级会员V4的分享 ························································································································································································ 解决： 1、尝试过开机按F1进入BIOS修改电脑时间，结果并不能生效，也不知道为什么。 2、在任务管理器界面上可以运行一些程序，结果也没成功调出设置菜单。 3、运行cmd，然后输入指令date，修改时间，闪屏会比较难输入，不过最终还是解决了
