✔ 最佳答案
This is a system problem, please check the event log in your windows. If your windows was restarted suddenly, it always occurs in your harddisk, maybe your harddisk has bad blocks. If yes, I suggest you to backup the data files and to replace a new harddisk for safety.
Remark: "Format Disk" is a way to solve the problem temporary, because the bad blocks will be marked during formatting. It is not a long term solution. Please take care!
