help! computer won't boot at all I have an hp and recently I was going to put more ram into it. I opened it and was checking to see which type I would need and I accidentaly knocked the chip out while the computer was on. Ever since then the computer won't start. All the lights come on and the disk drives start but the computer just makes a flat electronic tone for about ten seconds at time. I've tried unplugging and taking the whole thing apart but it's always the same and I don't know what to do.
