Does this sound like a dead CPU?

The computer is an HP desktop with an X2 3800+ AM2 setup.

About a week and a half ago my mom brought home a computer of her co-workers. When powered on, the unit send all fans spinning at 100% and there was no video or beeps. I tried a different PSU that is known to be working with no luck. I concluded the motherboard was bad after ruling out PCI cards, etc. and let her know what it would cost for a new motherboard. She said go ahead and get the motherboard. I just got it this weekend and when I installed it tonight I got the same thing. I tried to rule out EVERYTHING except the CPU. Since all of my stuff is Intel based right now, I obviously don't have a CPU. I can get a CPU for $30 but I don't want to order it if that's not my issue.

What do you guys think?
 
sounds like you have no control over the board or how the power is diverted around it so everything is running at max.
I would diagnose CPU and if you can get any CPU (doesnt have to be a new one just one that will work) then i would go ahead and test it.
$30 isnt bad for a new CPU so go for it :)
 
OK so an update... I got the new CPU, pulled the motherboard out of the case... and still the same damn fucking thing.

Any ideas?
 
How about the video card?
If there is no video then you will have power but it will never post so you will never get any beeps.
The other thing to check would be the memory- try leaving only one stick in, change sockets, try another stick. Memory is nortorious in keeping a computer from booting, but most of the time you will get to at least the bios.
 
I'm using integrated video but to be sure I plugged in my 2400 Pro with no success. I've never been this stumped when it came to a computer problem before...
 
Sorry to say that it looks mor and more like your first diagnosis was right- CPU

You've eliminated as the cause the PSU, motherboard, video,
so if the memory and connections are good then all that's left is the CPU

Sorry
