Wow, all I can say is that I am really pissed off. I noticed a few weeks back that my iMac was having Memory Intrusion Errors. The iMac in question is a 27" Core i3 3.2Ghz, 4Gb, 1Tb.etc machine. The machine ended up failing the Apple Hardware Test and the code ended up meaning bad memory (according to the Apple Certified Service Technician that I spoke to in person). It took about a week for them to actually get the new parts in for repair, they ended up replacing the Hard Drive (faulty firmware) and replacing the stock 4Gbs of RAM. I finally received it this morning so that I could reinstall my apps, backup my data and get to work on my already more delayed project. Everything seemed fine until upon boot I noticed that the fan was running in full blast mode even when idling. After reinstalling Snow Leopard and updating it I reran the Apple Hardware Test to make sure that everything was running properly. Of course it fails when testing the Logic Board (more importantly, the Fan Controller). The computer had no fan issues before I sent it in for repair, the service tech screwed up my motherboard while replacing the hard drive. To top it off he lied right to my face when I asked if he ran the extended Apple Service testing. To compare, this was my previous error that turned out to be the RAM. (Although it looks a lot like a Hard Drive failure code to me) And here is the previous Hard Drive's Firmware failing. Next, here is the memory intrusion errors. And finally, let's top it off with the computer crashing for no reason. I'm going to call up both Apple and the centre where I had the machine repaired (Carbon Computing, Authorized Apple Reseller) to demand a new machine. I can't delay my work any longer, it's already months overdue because of many problems.
