I have an intereted problem I want to post. I build a new computer, P4, 3.0 Gig with an Intel motherboard. I seems that since I took out the keyboard while it was on, it does not turn on after that. I did several testing and if I take out my ps2 mouse and keyboard and LPT1, it works fine but as soon as I put this on, it shutsdown. Have you people since this?
