No POST Take 2

I'm the guy who was wondering about a no POST problem last week.

RMA'd the moterboard.  I'm still having the same problem. No POST.  Monitor remains in hibernation (for all monitors used).  Fans on the motherboard spin (CPU and Case).  Lights turn on (DVD player, Main Power Light).  Everything that needs to spin, spins (Hard drive, DVD player, Floppy).  No beeps or blinking lights.

I think its near immpossible to get 2 broken motherboards that give the same symptoms. 

Here's what I've tried several times to fix it.  Check wire connections.  Check for grounding (removed motherboard from case and plugged everything in).  Romoved all but the CPU, memory, and video card.  Remove everything but the CPU.  Remove everything but the RAM.

For all of these the symptoms are the same.  The most distressing being the lack of PC Speaker Beep. 

Nearest I can tell its the RAM, Video Card, and/or CPU.  I hear that it is insane rare to get a bad CPU.  I ask again for your knowledge and suggestions /comp/.

Forgot, some of you like the stats:

CPU: AMD Athlon 64 3800+ Orleans 2000MHz HT 512KB L2 Cache Socket AM2 Processor

Motherboard: Gigabyte GA-M55SLI-S4 Socket AM2 NVIDIA nForce4 SLI ATX AMD Motherboard

RAM: gigaram 2GB (2 x 1GB) 240-Pin DDR2 SDRAM Unbuffered DDR2 667 (PC2 5300) Dual Channel Kit System Memory

Video Card: eVGA 256-P2-N554-AX Geforce 7600GT KO 256MB 128-bit GDDR3 PCI Express x16 Video Card

my mb has NEVER beeped. ever. it's an ecs piece of shit. but don't go by no beeping as the only way of saying your mb is fucked. could also be that your powersupply is faulty/dying. from your post that seems to be the only thing you didn't replace. i know on my old powersupply i would have to hit my power button 30 times or more before the computer would actually turn on. now with a new power supply the first press works every time.

I havn't replaced with new parts anything except the motherboard.  The instruction manuel says its supposed to beep on start up.  One short for good and it gives the beep code for the Bios.  The PSU is as new as the rest of the computer. 

The PSU is a  Rosewill RD550-2DB-SL 550W Active PFC Power Supply SLI Ready ATX Form Factor 12V V2.2

Everything else powers up just fine...

The problem was solved by reading another mobo's troubleshooter.  Clear CMOS and WAIT one minute.  This was done on my first mobo (still was a dud), but in my rush and rage for this mobo, I forgot.

Sum it up.  I was impatiet and stupid.  Sage to prevent bump.
