Oh no, not another no beep, no video....

[donahu1]

Yes indeed. I've felt guilty piggy-backing on another thread by asking questions there. Here is my situation: I've followed suggestions of pulling ram and listening for beeps (there are none). I've disconnected everything but my video card, PSU, PCU and still no beeps, no video.
I finally concluded faulty video card (wrong) Well, I finally concluded it was my MOBO so of course I went out and bought another one. (wrong) Hmmm well I finally concluded the CPU which I recently purchased OEM was DOA just more than the 30 day warranty from Newegg. Yes you guessed, I have another CPU on the way. Needless to say I sure will have a lot of parts when this is over. If it is not the CPU I give up. Never had a dead processor but I suppose it happens. Thanks for all the advice and I'll let you know if this is "finally" a solution..

CPU's can definitely be bad from day 1. You will at least have the essentials for a second PC, which you could then sell on ;)

"I've followed suggestions of pulling ram and listening for beeps (there are none). I've disconnected everything but my video card, PSU, PCU and still no beeps, no video."
What's a PCU? Do you mean CPU?
If running with the bare minimum [with the mobo out of the case on a non-conducting surface]...
PSU, mobo, CPU+heatsink+fan, internal speaker...
Momentarily short the on-switch pins on the mobo to Startup. [Your switch might be faulty, so no switch-on]
And still get no beeps even though [there seems to be life/power, and] you believe your internal speaker works...
That would suggest the POST isn't running.

Is the system "not dead"? Signs of life? Getting power?
Any sign that the POST is running? LED's blinking at any time?
First thing to check is the PSU, or use one known to be good.
Then have the few other connected components tested = mobo, CPU.

Yeah I meant CPU not PCU. The system when the drives were all connected had all the LED's on. Harddrive constant and so was the floppy active. CPU fan was working as were the on-off switch and case fans (Antec 900 gamer)
I even went and bought a PSU tester ($20) and the power supply was all green for all voltages...
Newegg will deliver the Athlon x64 5500 tomorrow and I'll know for sure. Thanks for your help. I've built 6 computers and never encountered a dead processor so now I'll know....

Silly thing - but just for completness - is there a four-pin accessory power socket in use on the mobo?

[donahu1]

Answer is yes there is a 4pin plug in and it's plugged in. My problem is indeed solved!
It was a DOA processor I received through Newegg. Like I said never happened to me before. Sure enough, as soon as I slapped the new one in today, it posted and I am formatting as I write this note.
Thanks for all your help people. I guess we now have to consider the DOA in the future for these threads. Everything else failed to correct the situation. I wondered who in their right mind would be posting messages at 3am but noticed you are half way around the world so it makes sense now.......

[Paul Komski]

Just about anything in a PC can be DOA. Most commonly they are components with circuit boards or moving parts or any sort of storage medium. Even screws can have been stripped or tubes of paste gone solid. The failed CPU -v- failed Mobo is a long-standing conundrum.
