I have a problem that is strange. Turn on computer and no post. Turn off computer and disconnect power then turn on computer and it starts. This has happened for a week. Now I can get nothing. The HD spins, the fan runs, the power light is on but no Beep for post and no startup. I have stripped it down and reset CMOS checked all the components including the keyboard and monitor on another computer and all works fine. Any ideas would be appreciated.
