HDD Light constantly flickering

[edifice]

Hey Guys,

I have just updated Windows 7 64 bit Ultimate to SP1, and my HDD light is constantly flickering? There is no discernable differnce in the performance of windows and it boots and runs fine, it's just that the light is a bright neon blue colour and is very distracting!

It happens from the moment my desktop appears or when being online like I am now typing this. Can ANYONE please shed some light on this matter? I am at my wits end LOL!!!

A friend did tell me that turning off SUPERFETCH in the list of running services might work. I did this when I originally bought and installed 7 as I was having the same problem then, this time however, it's not had ANY difference, I still get a BRIGHT blue light constantly dancing beneath my eyes.

Please HELP!!!!

In Windows Task Manager, select Resource Monitor and select Disk, and keep an eye on what is writing or reading the disk the most. Maybe you will notice the service or application. If it is a Windows service (svchost.exe), you probably can't do much to stop it, so put some tape over the LED.
