Hi
Have you tried
Reseating the cpu tray
Reseating hdd
Reseating ram
Reseating gpu
That’s what I do on my 5,1 when it doesn’t chime or boot
Hopefully this answers your question
Thanks:)

let me try it thanks man
Gotcha
If it didn’t work give me a shout and we will keep trying :)
Case Update, after i change cpu from 2 x X5690 back to 2 x 2.26GHz it work again , is my X5690 cpu dead ?
To confirm that I would see if you can find a old motherboard with the same socket as the cpu and check them out or try plugging them back into the Mac Pro as it was have just been a strange case of bad luck :)
