Hello, I installed the 604ev card processor in the 9600, removing the NewerTech g3/445 card, but was unable to boot.

Tried to boot from the HD, and the 8.5 original CD I own.

Tried to reset the CUDA chip, then the logic board disconnecting the power supply and removed the battery.

Tried to reset PRAM from the keyboard with COMMAND+ALT+P+R

Nothing ehappened.

No sound when powered on, no video, only some noise from the HD and the fan

What other can I try to do?

Please help

Thank you

John
