Well it has taken about 2 months on the phone with Apple Support and speaking to 3rd level support but I have a solution.
Apple Support gave up on the issue and sent me to a support center. I went to NextByte in Brisbane City AUS and they replaced the RAM (both 1GB chips) and it works a treat!
They dont know why, but all of you that have this issue, give it ago!
Cheers
