Why does the hard drive light on my Dell PC flash constantly even when I'm not doing anything or when its on stand by. I know that its normal to blink while using a program, etc. but should it be blinking all the time? Its never did this before. This computer was completely wiped clean at my job so that I could take it home to work from a Terminal Server. It never blinked like that at work but its been doing it ever since I set it up. Please help?
