With my PC completely turned off, if I turn it on with anything other than an ethernet cable, mouse, and keyboard plugged-in, then the BIOs will simply not post. It just hangs at a blank screen with a tiny white line in the upper left corner of my monitor. I need to unplug anything else but what was mentioned, and then press the restart button and it will proceed as normal. Easy work around, but would really prefer to not have to do this on the rare occasions that I turn my PC off, or when it needs to be restarted, and it's something that your PC shouldn't be doing in the first place.
