I have built 3 computers in the past, and just completed my new machine and have the following issue:
Turn on the power switch at the back of the case and the:
1) 'green light' on motherboard comes on
2) All the fans start up
3) Hard drive number 1 turns on (felt for vibration)
Then I press the 'power' button on the front of the case and:
1) DVD's power up (lights come on)
But no boot up happens or
1)No 'HD light' on case front
2) No signal to monitors
3) No 'power on' light on case front
