Boot problem

Users questions: Are displayed for each boot disk has an error, open the BIOS hard disk column shows the CPU fan speed OPRM, to turn over before boot.
Experts answer: "Open BIOS hard disk column shows the CPU fan speed OPRM, to turn over before boot?" BIOS inside the fan speed is the main Board itself detected, probably can not manually change it? Recommendation: 1, test hard disk using Disk Utility to see whether the bad sectors, if the timely processing, or will expand the two, check the motherboard's sinking, silver oxide battery, if the power shortage, so you need to be replaced
