Everytime I install something(or unplug the computer for a while) it will not start. I believe this is a bh6 problem. Usually I can just turn it on and off for a while(usualy over the coarse of an hour!!) and it'll miraculously turn on. When I press the power button everything seems to power up fine(fans spin, cd-rom's and hard drive start to spin-up) but my monitor never gets a video signal. What could the problem be?
