Q: My machine configuration is good, but why in each boot when the power switch, to wait four or five seconds after the CPU fan began to rotate. But everything is fine with the machine.

A: There are generally two reasons for this phenomenon:

One is that there is a problem with your CPU fan. The fan may be of poor quality or lack of lubrication. If it is a new purchase, that is, the quality is not good, to find a business for another, if second-hand, may be the lack of lubrication, add some lubricating oil is. Refueling, you must first remove the fan screws, and then the fan upside down, carefully pick out the circle of stickers, and then to the edge of the shaft into a small drop of lubricating oil, and finally paste cellophane good.

Second, the host power supply of the start delay circuit has problems. Can be changed to a normal power supply to try.
