I've been having a problem lately with my computer. It's running 64-bit Windows 7, and has two external hard drives plugged in. Occasionally , I've noticed that sometimes when I attempt to do something in a program, even something as single as right-click on a cell in Excel, the computer will hang for a second, sometimes all the programs will become unresponsive to clicks while this is going on. Meanwhile, while waiting for the context menu to open up, I can hear one of my external drives wind up to speed. The program won't respond until the drive has wound up to speed. The curious thing is that the program I'm working on shouldn't be touching the external drive at all. In fact, the last time it happened, which prompted me to post this, I didn't have anything open that should be accessing that drive. Yet, it still spun up when I right-clicking on something unrelated to it. Neither drive has ReadyBoot activated, Windows wouldn't allow me to active it on them even if I wanted to. I don't know what might be causing this.
