I have an old pc I'm using as a fileserver and have this odd issue. Recently I added a new external USB drive for more space and noticed that when I power off the computer, the CDrom and Drive access light stays on (yeah, weird). If I unplug the USB drive, light goes off - this is when the computer is off. Now here's the kicker, the computer won't power on unless I unplug the USB drive. It works ok after I unplug the USB drive, power the computer on and plug the USB drive back in.
I leave this pc on most of the time so it's no biggie, just a quick shuffle with the USB cable if I reboot the computer or something. Reboot thru software is ok, only when I shutdown the computer by pressing the power button and try to turn the computer back on manually that this problem happens. It's an old pc so I really don't want to spend too much time troubleshooting since it's due for an upgrade sometime this year anyway.
