I have a Macbook Pro Intel Core Duo with 2GB of ram and a brand new 320GB HDD installed. I am running Snow Leopard and I am currently updated. The problem did not start after an update. It just randomly started. The problem that I am having is that the laptop is constantly freezing. I replaced the hdd because I thought perhaps it was a dying hdd but that did not fix the issue. I replaced the ram with (apple) ram thinking that perhaps one or both of my sticks were bad. This did not solve the problem either. I replaced the HDD cable inside because I thought perhaps it was the connection that had gone bad but that did not fix it either. I have run disk utility from the start-up and that did not fix anything. I also have re-installed many time to see if that would fix it. I have formatted by writing 0's and also a straight format and neither fixed the issue. I have run tech tool pro on it and found no errors on any of the devices. I have reset the PRAM/VRAM and the SMS but neither have helped. I also disabled the SMS through terminal and that did not fix the issue. I am out of ideas for how to fix the freezes.
Let me explain what I mean by a freeze. When I am on the computer I can move around and almost every 2 to 3 minutes open a program that will cause the spinning rainbow to appear and although I can still move the mouse and the dock will pop up if I move over it, nothing happens. I cannot do a force quit and have to wait patiently for it to stop circling or if it never does stop I have to hold the power button down to shut it down.
Does anyone have any ideas what could be causing the constant freezing? The odd part is that with an external usb HDD I have no issues whatsoever. It never freezes and if it does I can force quit the application that has stalled. I do not know what that means but it seems that the connection from the internal HDD to the Logic Board is faulty and I don't know how to make it work correctly. I have checked and re-checked all connections internally and they seem sound. Ideas?
