Some kind of cooling problem or logic board?
Hi, I'll try to describe my problem...
when I sart up the mac, the boot goes well up 'till the grey apple logo when the "hold wheel" freezes.
If I try to boot the mac for 3 or 4 times in a row, the monitor starts to display lines and dots randomly.
At the fifth or sixt boot the lines and dots get worse.
If I try to boot after few hours... no lines or dots...
I opened the case and I can tell that the CPU heat sink was quite hot... but I heard the buzz of the CPU heat sink fan.
What do you think?
sorry for my bad english...
Is this a good question?
