Hard Drive light continuously blinking

Anyone know why the hard drive indicator light will continuously blink about once per second no matter if I am using the computer or not? I can't help but think that this could cause some slow downs in gaming and produce unnecessary wear and tear on my hard drives.
My system is about 2 months old and the light has been blinking since I put the system together.

What are system specs? If you dont have enough ram, windows will constantly have to access the pagefile, and cause such symptoms.

Nothing is overclocked.
