Trying to work this one out.

MBP ~2011 13", has had a spill on keyboard BUT, will boot perfectly from another Mac's firewire'd target mode hard drive. The only broken hardware appears to be a usb port and the trackpad. It otherwise functions fine.

If I try to boot it from its own drive or a Snow Leopard DVD, it gives the 3 beeps.

So I've replaced the hard drive, and went to install from the DVD but still giving the 3 beeps.


I mean, if it works fine over Target Mode, doesn't that prove that everything is fine except the HDD?


(I am aware 3 beeps is a RAM issue, have tried every configuration of RAM/slot and the pattern is the same, no boot from own drive or DVD but ok boot over firewire)
