Hi all.... First time poster here.....hope someone can help. I just purchase a ECS P6BX-A+ slot 1 motherboard. I took a PIII 550 Slot 1 CPU out of my Compaq P550 machine and attempted to install onto this motherboard. However, I cannot get any type of life from the board with the PIII chip in there. It has me wondering if I can actually use this CPU on this board. Is there something that I am missing or forgot? Any help or pointers will be really appreciated - thanks!
