ubuntu总是重启，不知道啥原因。记录下查找过程
问了chatgpt原因，叫我查看一下log
/var/log/syslog
/var/log/kern.log
/var/log/auth.log
叫用指令last, uptime, journalctl, dmesg这些指令查看，log里啥都每看出来。
查看cpu温度也还好

也没啥问题
参考ubuntu训练深度学习模型电脑重启解决方法
把显卡功率设置为了100w。再试试看把。
还有个可能的原因我把主板上的两个风扇拔了，这两个风扇用来给cpu降温的。太吵了。
99%确定问题了
是插排的功率不够，主机电源直接接到墙上的插孔。文章来源：https://www.toymoban.com/news/detail-526775.html

不完全是电源问题，我将点云接到墙上插孔后，仍然会不定时重启，只不过间隔时间变长了些。
后来我从主板上拔了两块机械硬盘，重启间隔时间从1-2天，变为了7-10天。
找不到原因，苦呀！文章来源地址https://www.toymoban.com/news/detail-526775.html
