I open and played around with my system a little bit . When I started it up after,nothing worked, I can hear the memory count only. I do not see a system or hear any beeps.( no display, it powers up ok) Even if I unplug the monitor or the key board,and restart, I do not get any beeps after the memory count. Can somebody help me please.Thank you Visit our website regularly for FAQs, articles, how-to's, tech tips and much more http://freepctech.com
