I have a XPS 710. When I hit the power button it starts the fans up for about 1 second, then nothing. No lights, no beeps. Inside the case, i see that the cpu, video and case fans all start for a second. My initial thought was power supply since I change it 3 months earlier when the original power supply died (after 3.5 years). I replaced power supply again, no changes. No beeps, no lights (of course button lights when you first hit it).
I removed all components. Being Video Card. unplugged all hard drives, DVD drives, etc. removed memory looking for beep errors. Nothing.
My thought is it is the mother board. If so I will build a pc and not buy another dell (i need the main Hard drive intact and running).
Any thoughts/suggestions or is my theory correct?
Based on what you have posted I would agree the motherboard is the most logical problem.

I had the same problem ... it was the power button wiring inside the case: loose power button connection. This button is more than a simple on off switch. Once, my 710 froze during the bios phase of the boot. Had to unplug the main power cord, press the power button for 10-15 seconds, replug the the power cable & press the button again ...
