Thank u for reply

but still the same( can motherboard might just burned some connections for the bridge which supplies power for one half of a socket and PINs?

Normally, a Mac Pro will not even boot with a failed CPU. Thus, maybe you have a single CPU, 8Gb installed?

No no its a 2 xeons, ive dispanded and swaped cpus to the sockets , i also swaped rams everything seems to work fine

Ive sorted it out , CPU released some kind of a acid... thats what she said

so i cleaned my CPU with Ethanol and it works !!!!
