1. Use a hard disk detection tool to check the hard disk to see if there are bad sectors or something. Common DOS tools have them, such as MHDD;

2. Repartition your hard disk, change the size, and format it. Do not use quick format. Of course, if there is no data, it is better to delete all partitions and rebuild;

3. Check whether the data cable and power cable of the hard disk are in good contact;

4. Check the memory Whether it is loose and whether the gold finger is oxidized, you can also try changing the memory to another slot after these are dealt with;

5. Check whether there is too much dust in the chassis.
