What to do when the hard drive light is always slightly flashing

Recently, I reinstalled Win7, without installing any software, and not connected to the network, I found that the hard drive lights always flicker slightly, about 2 seconds apart, when the system is not operating. I began to suspect that there was an unknown process in the read and write hard drive, so downloaded Filemon for monitoring, but reported no sign of any read-write hard drive, can be hard drive lights or flashing non-stop! Excuse me, what's going on?

It is possible that you have installed some software in the version, boot loading programs, services will also increase, if only virtual memory some read and write action, due to the special area of the hard disk, Filemon is not necessarily included in the record range, you can try to "start" → "Run" Enter the Msconfig command, and then remove non-essential Startup items, and then restart the test, it is not possible to reinstall the original system. In addition, there may be a problem with the hard drive LEDs, LED lights are based on the level of the size of the light out, if the motherboard on the HDD LED interface or chassis front panel lines have problems, anti-jamming ability to download, will also cause a slight flicker, in fact, the effective way is to open the chassis to listen to the hard drive has the sound of rotation.
