ML350 G5 won't boot, red internal health LED, system board LEDs going amber

[delongima]

I've got an ML350 G5 system that won't boot.when i turn on it ater 20 sec  The internal health LED going red,and  there are eight LEDs next to the System Fan 1 connector and the two of those that are closest to the RAM sockets are flashing.  I can't find anything in the Server Maintenance and Service Guide that references these LEDs.

I also Power-off system, remove battery, remove all the RAM and put 1 back, switch 6 on, put battery and power up PC. It just makes that noise for hours and no change

i remove PCI cards and DVD/RW cable too, but no change appear!

even changing system power doesn`t get any result.

Can anyone point me in the right direction?
