Asus P6T Deluxe V2 motherboard won't post

If the cpu is messed up, the mobo can't beep.

So I would check the cpu, also. Mobos have been know to take them out when they go. It's not usual, but it happens.

I would also do the testing with the mobo out of the case (on newspaper, cardboard, something non-conductive) with 1 known working stick ram, video, psu. And manually jumping the power pins on the Front Panel header pins.

I haven't tested with the mobo out the case, since it worked for 2 years in the case.  I'm not against doing it, just didn't figure the probability was high that this was what went wrong.  I have ordered new ram to test in it and a new power supply and new video card.  I have tried booting it without a video card at all and it doesn't do any different than with it in.  So that leads me to believe that the video card isn't the problem.  I really just feel it is the power supply even though my tester says it is ok.  It was a rosewill and it's ratings are only average.  I have no way of checking the CPU except for swapping out other parts.  It is an i7 and they are still very experiences, so I can't buy another for testing.  I'll try it tomrrow on the paper with no fans, etc plugged in and let everyone know.

>> ...since it worked for 2 years in the case

yeah, it's probably not necessary, but it never hurts to take it to basics if the first idea didn't work.
I learned the hard way to always try a replacement mobo before installing it in a case.

>> I have no way of checking the CPU...

You could call a couple of local repair shops and see what they charge to test it for you.
If you know all the other parts work, the "process of elimination" method is pretty reliable though.

you can always open it, and do a visual inspection of the capacitors for leaking or bulging ones

First make sure all cables are connected well,then clear cmos.
As mentioned above by durrence make sure spaeker is connected(internal)
Only have memory and video card,cpu (of course) attached,then reboot note any beeps.

I think the general thoughts are that the power supply is bad.  I have ordered a new one and some additional ram.  I'll test these and let everyone know what I find.  They should be here later this week and I'll test over the weekend.

I had checked the capacitors on the original motherboard and the RMA motherboard and there were no bulging tops.

I've tried the bare minimums in regards to cable hookups, and the CMOS should be at factory defaults due to the motherboard being a replacement one.  The old motherboard had factory defaults also, since I don't overclock or anything.

Just for the heck of it, double check that the BIOS jumper is in the correct position.
I haven't seen it done in a while, but a few years back I would get a mobo with the jumper in a neutral setting. It was done for shipping reasons.

or remove AC cord, and bios battery for a minute

So what was it?

It was in fact a bad PSU.  Even though my tester said it was good, it was bad.   Like others said, my tester is pretty much worthless since it doesn't test under a load.
