had a search through the forum to no avail.
i have 2 new 2GB sticks (rated at 800Mhz). when i put them both in the machine, it won't boot past the black screen.
when i use either of them with either of the old 1GB sticks in either slot, system boots to 3GB no problem.
tried resetting PRAM, NVRAM and SMC but all to no avail.
difficult to understand whether the problem is with the machine or the ram - any suggestions?
thanks
