Yesterday, I installed CentOS7 on my computer, and I also dropped the Win7 system. Since then, Only Centos is installed on my computer, which gives me a feeling of abandonment.
A HALT command tried to shut down the system, but found that the screen wasn’t black, that the machine wasn’t working, and that the power light was still on. So it did its best to hold down the power button and force it off.
When I came back the next night and started the machine, it was abnormal. After starting the machine, there was always an ATA Bus error. Please see the last picture for details.
How to do, Lao Tze did sth. for two or three hours, reinstalled three times the system is the same result! No way I’m white.
Finally search, omnipotent netizens said that the hard disk fault, but my hard disk is absolutely forced not to be broken… In the end,
I tried to solve my problem with one of my better tools, the CMOS discharge!
Think back, the last time I did this was ten years ago, and alas, how time flies… Beside the point.
Yes, open the case, take out the piece of electronics on the motherboard and put it in again. Restart it.
 
It’s a bloody lesson to shut down the halt command.
No, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no. Finally, I have an error report.
