Weird hardware problem
Last week I shut down my P4 system (which had been running for a few months). Went out of town for a week, came home, hit the power switch and... nothing.
Yup. Happened to me a couple years ago. Machine was off for about a week, turned it on, PS was dead.
Loose connection somewhere. My first thought would be the connection between the power supply and the power switch. That could've gone out months ago. After that I'd try the connection to the motherboard.
Something very similar happened to me recently. Normally, we never switch the machine off at the wall. But, one day we did. When we switched it back on, it was as if it had forgotten how to wake up again. The "on" switch just didn't do anything. They replaced the power supply under warranty and now its fine.
My modem did that.

If your cdrom and hard drive does it's boot up initialization spins, but you don't get your happy BIOS beeps it could be the capacitor on the motherboard. I had one system die that way. The capcitors from 2002 is suspect because of a capacitor formula scandal in asia.
One day my monitor wouldn't turn on. It was just dead. So I went out and bought a new one and gave the old one to my wife's brother who "likes to fool around with electronic stuff".

The first IT technical tip I ever remember receiving was from my highschool computer science teacher. (we were using the old blue screen macs back then).
I had a similar experience once a long time ago when ATX power supplies were very new. I ended up resetting the BIOS settings using the little red jumper, and then everything started working again.
Is the PS circuit breaker set to "on"? ;)
Do you hear the power supply fan whirring? Do you see any hard disk activity lights?
My old K6 did that *every* time. Solution was simple, yank the cord out of the PS, count to 3, plug back. Counting to 3 was *very* important.
Unplug the power supply - hold down the power switch for 30 seconds or so, and then plug it back in. I had a newer power supply that would forget how to turn itself back after it was shut down a certain way. Unplugging it and getting it to use up the charge in the capacitors would reset it and get it going again.
Whoa - that did it! Unplug, hold the power switch in for 30 seconds, plug back in, hit the switch, and it came right up!
