Well I just got into the idea of building my own computer and decided I would educate myself with an old HP of mine from 07. Well I got it apart and decided to take the whole thing apart. I then decided I would clean it and my dad suggested a vacuum cleaner. I know bad already Well I cleaned the whole thing on a carpet with about 75% humidity and attempted to put it back together. It is a HP a6683w and I believe I got everything plugged up right and all good. Next I plugged it up and it turned on and the fans ran the cycle and what not. The problem is that the monitor and I tried 2 reads NO SIGNAL. Now I probably destroyed the whole thing but it turned on fine and the fans, so is something unplugged or in the wrong place??
