Hello, I have a big problem with my new 20" iMac. The computer crashes without any reason. At first I though it was Autodesk Maya's problem, but then I noticed it also crashes in other programs. When it crashes, the watch stops, and I can't do anything, but the mouse still works and the CAPS LOCK light still works. I cannot force to quit anything and the only way to restart the computer is holding the power button. I run the Hardware Test 3 times, and each time it gives me the same error code: 4MOT/1/40000003:HDD What is this? I guess I have to take it to Apple Technical Assitance right? Thanks Nicolas.
