The hard drive activity light on my case is constantly blinking. It seems to work normally when the drive is active, but even when the computer seems to be doing nothing, it blinks at a rate of about 1/sec. It has done this ever since I put the system together about 6 weeks ago, and the computer seems to be working alright otherwise. Any ideas what might be causing this?
