Running system now wont enter post

I've had a stable running home built system for about 10 months now. Just recently, I began having problems with my CD drives (they would be unavailable in XP). Then tonight, while I was rebooting my system to get the CD's working, I powered it off and it will not even enter POST. Pressing the power does nothing. I checked the switch and it is closing properly. I disconected all drives and still nothing. The green light on the Asus A8n-SLI Premium is on solid and the PS seems to me working, though I dont have an official way to check it. Any suggestions before I strip it down and bench check it?
 
I don't know if you tried this yet, but did you reset the BIOS?

If you don't know where the reset jumper is on the mobo, you could always just pull the CMOS battery (looks like a watch battery) for a few minutes, and then reinstall it and try booting up.

I apologize if I'm being sophomoric, but seeing as you only have two posts here I can't really gauge you're experience... In any case, good luck.
 
Not a problem... I'm fairly experianced. On the A8N-SLI, the proceedure is to pul the battery and move the jumper right next to it from 1-2 to 2-3 for about 10-20 seconds. Yep, I tried that right after I posted here and the results are the same. I'm going to head out and get another PS and try that.
 
When you ppress the power button, what happens? Does it sound like it boots up, just turns on, or just turns back off? You could always try to induce a response out of it by starting without a video card, or mem/cpu. That would at least tell you that the mobo is at least trying to start up.
 
That's exactly what I do, take something out to see if it gives me beep codes because of it.

Also, as nocturne asked, please better describe what happens:
The PSU turning on? Does the HSF start spinning? HDDs, opticals? You have a speaker connecter to the headers right?
 
Well, it ended up being the power supply. Thanks for all the help! Now I have to deal with Antec's <cough> <cough> steller RMA procedures to get this thing replaced.
