Component Order Which POST Goes Through? No POST/Video Problem.

Hi guys, quick question for you:

Just finished a new build, and I'm getting no beeps at post and no video output.

I stripped my system down to 1 RAM, CPU, and CPU Fan.

With RAM in, there are NO beeps.
Without RAM, it successfully gives me the no memory beep.
With the 4pin CPU power connector unplugged and NO memory, there is no beep.
With the 4pin CPU power connector PLUGGED in and with NO memory, there IS a no-RAM beep

The motherboard is fine. I just replaced it 2 times. Plus the fact that it beeps when there's no RAM in, makes me think it's fine as well.

So is it:

1.) RAM – With the RAM installed i get no beeps. With no RAM i get beeps.

2.) CPU – It is producing some warmth. It gets mildly warm after powering on for 2 minutes. Could it still be defective?

3.) Power supply – The PSU fans remain on and it's running my case fans, my video card fans, and its blue light stay on. Could it be a faulty PSU?

Or maybe the CPU? I heard if there's no beep then it might be a dead CPU

What's the order that the post goes through? Is my CPU passing and the RAM defective?

Mobo is Asus P5QL Pro, CPU is Intel Q9400, PSU is Rosewill Stallion Series RD500-2DB 500W, RAM is Mushkin 996587

Thanks in advance.

What video card?
Have you tried clearing the CMOS?
If you have another PSU now is the time to try it.
Do you have the board installed or on the bench?

Don't have another PSU, but i'm gonna RMA it. Video card is Sapphire 4870 100259L.

However I can't even get a warning beep that my video card is not connected. I'm just running CPU, HSF, and 1 RAM.

I can get the warning beep that I have no RAM installed. That's it.

CPU fan spins, case fans spin, i'm almost positive motherboard is fine.

Has to be either the PSU, RAM, CPU no?

Guess I'll start the RMA with the PSU first.

Noway would I risk that card by using a low quality Rosewill PSU look for one of these brands and models in at least 700w to power that card>
Brands and Models of Quality Power Supply Units
Seasonic - any model
Corsair - any model
Thermaltake - "Toughpower" series only
Coolermaster - "Real Power Pro" series only
PC Power & Cooling - any model
Silverstone - any model

It could also be a short to the case do you have the board in the case or out?
Have you cleared the cmos?
