Did i kill my processor?

[Zen]

I tried to change the mobo in my PC (P4 2.0GHz, skt 478) for one with both
PCI-e and AGP 4x and install a PCI-e graphics card Asus X1600 Silent. After
screwing everything back together, everything powered up. All fans, HDD, &
DVD but no video to the monitor. I removed the X1600 and tried my old
Graphics card in the AGP slot. Powered up and same problem.
I thought this may be because of a fault with my new Mobo so i changed back
to my old Mobo and get the same problem. Everything has power but no signal
to the monitor or BEEP from the case speaker. I tried removing components
one by one to see if any were causing the problem but nope.
I found the CPU & HSF hard to remove from the first mounting but the pins
all looked ok. Tried resetting CMOS and using a larger PSU.
Any ideas which could help would be appreciated.

Thank you.

Did you remember to connect the ATX 12V 2x2 square power connector ?

Try your old motherboard, with just the processor and motherboard.
Connect the computer speaker. If the processor is good, it will
execute the BIOS, and will give a distinctive beep code, indicating
it cannot find the memory or the video card. That would be
evidence that the processor was still good. If processor + old_mobo
gives no speaker beep pattern, then it is likely the new motherboard
fried the old processor.

Got that connected.

Still no beep. Guess it's fried.
How / why would a new mobo kill my processor?

Well, if the motherboard received any testing at the factory
at all, it shouldn't fry processors.

The simplest way to fry a processor, is for the Vcore
regulator to go nuts, and put out more voltage than the
processor can take. Are you certain that the new
motherboard is compatible with the old processor ?
Does the motherboard maker have a CPU support web
page ?

I have/had a 2GHz P4, not sure which core, my pc dates from mid 2002.

I now have a 2.8 GHz on order from e-bay, I'm thinking of getting someone to
have a look at it for me before i plug it in.
I was planning on using the new mobo with graphics card to delay building a
new machine but now i'm getting a faster cpu it makes things cheaper for
now.

As another point i realised that my new case is an inverted ATX design (Lian
li V1000+) and my X1600XT Silent uses a heat pipe for cooling, i can't find
confirmation on-line about this but i'm guessing it could cause problems.

Thanks for the help.
