replaced logic board. now boot hangs with logo ticking, then restarts

have tried everything apart from a new hdd & doing a fresh install. can only get snow leopard disc to boot. hard drive failure? does the logic board need flashing?

回答此问题我也有这个问题

这是一个好问题吗？

I would reset the SMC and PRAM first, then try booting to working external hard drive or USB.

Also, try booting into Verbose mode so that you can see where it is hanging and restarting.

这个答案有帮助吗？
