Brett, Thanks for the reply. I took your advice and tried a couple of things. First, I jumpered the on/off switch connection on the mobo and still got the same results (nothing spins up, red LED on mobo comes and stays on). Secondly, I jumped the 14 and 15 pins (with a bent paperclip) on the ATX connector while leaving one HDD (and absolutely nothing else) plugged in - nothing happened. If I understood you correctly, that should at least power the HDD up? Are there any other visual/aural clues that I'm looking for? Should the paperclip get warm assuming there's a current passing through it? When I plugged the cord in from the wall into the socket in the back of the case, I did hear that "click" (for lack of a better word) you hear when you plug anything into a socket. I know at least the juice is getting into the box... Based on this, would you assume the power supply is the likely culprit and that the next logical step would be to try testing my hardware on another ATX power supply? My only concern is that the LED lights up, which to me would mean the mobo is getting >>>some<<< power. Let me know when you get a chance and I REALLY appreciate your advice and suggestions! :) Thanks, Tim

Thank you for all that responded. I'll try to summarize the answers to all the follow-up questions in one reply.
When I turn the power on, nothing happens except a red LED on the motherboard lights up. The CPU fan doesn't spin, the computer doesn't beep - nothing (so no beeps or POST codes). The weird thing is that when I turn the power switch off, the LED stays lit for another 5-6 seconds. I'm not sure if that means anything though...
That's just the capacitance stored up in the MB caps. That's the reason people say to wait 10 seconds between powering off and powering on. This also would seem to be a sign that the PS is feeding power.
Do the power supply fans spin?
I assume not, since he says above "nothing happens" :-)
the Abit NF7 with MB LEDs has two power LEDs - the red one, when lit, indicates standby by power. The green one, when lit, indicates the machine is powered up.
You seem be stuck in standby mode. Try the front panel power switch a few times. (Count to 10 between each try, see if green MB LED turns on)
Good point. Maybe this is what you meant but also try holding the button for 5-10 seconds as well.
If that doesn't work, try "aggressively" using the front panel switch. Sometimes the front panel switch start to fail and they have a hard time turning on the signal that tells the system to power up.
Just trace the switch wires back to the MB jumper header then manually jumper the connection yourself. If there are 2 wires the jump is obvious--3 wires you may want to check the MB manual to make sure you jump the right ones. Only need to jump briefly...this will eliminate the switch as the culprit.
Also try unplugging the PS from the wall for 30 sec to cold cycle everything.
Also, you can check the PS simply enough (assuming it's an ATX): -unplug it from the MB (leave at least one HDD connected for a load...PS will power off if no load) -compare the MB connector to the one here: http://xtronics.com/reference/atx_pinout.htm -if the same, jump (with paper clip...be careful!) pin 14 to 15 together -PS should power on (fan(s) spin, HDD(s) spin up)
I stopped in at a computer shop on 122A in Holden this afternoon and was quoted a $35 "bench fee" for taking a look at it and $75/hr to do any work. Like I said before, all the parts are still under warranty through New Egg and I'd happily send them back but I need to figure out what's not working.
Forget PC shops, IMO...they're only going to do the simple tests you can find on lists like these anyway ;-)
