I was pretty much given a HP computer with printer and scanner. Which is maybe 3or 4 years old I would guess. The CPU is a micro tower, I have never seen one this small. So last night I hook it all up. At first it does not beep at all, then later it beeps 4 times. The monitor says to check video connection. All seems well, still won't do anything. I hook another monitor up that I know works, same thing. I take the cover off and check for any loose connections. The power to the hard drive is loose. I then reseat it and the computer boots up great. But now I must hold the power button down for at least 5 seconds before it will power off. It will reboot just fine but if I shut it down it does this same thing again. If I unplug the power to the HD and the plug it up again. It boots up fine. It is running Win98 SE. Could this be a software conflict or virus? This thing has tons of different programs on it.
