(note my profile name, and respond with kindness, please ) I will try to be concise. I won't chronicle ALL the phone calls and visits. 1) I purchased a 20" iMac in August 2006. It began having serious issues last Fall, including, but not limited to, automatic restart. My local apple-authorized store recommended an upgrade to Adobe CS3 to fix it. $400 out of my bank account. The machine continued to misbehave. Took it out of town 45 miles away to an apple store. When the apple genuises there could not correctly diagnose it, my apple care finally agreed to give me onsite support. The power source and logic board were replaced. 2) Shortly after, the machine began doing quirky things, AND once again the auto shut off and restart. This time, the product specialist I was referred to was highly sympathetic and agreed to arrange for a brand-new imac to be delivered. That was comforting. 3) The new imac ran like a charm for about a month. Then, one or two random restarts. I was in denial. It began happening more frequently. A phone call to apple care and another convo with a product specialist. Another onsite visit, with another new power source and logic board. Same onsite tech guy, who agreed that I have phenomenal bad luck, AND that he's seeing more of this with the increase of parts made in China. 4) The new imac ran like a charm again for five days. Then, auto shut off and restarts again. Another call to apple care. I was moved quickly up the food chain to a manager in Texas Corporate Offices. Two hours on the phone and he agrees to credit me $1399 of my original $1799. I put in another $600 and ordered a macbook pro. HERE'S MY QUESTION: Does lightning really strike this many times? Is everyone missing something? Can it be a virus? What the heck is going on? I freely admit I am not tech-savvy (I drive the car, I don't know what's under the hood), but this seems too bizarre to be true. CAN THAT MANY POWER SOURCES AND/OR LOGIC BOARDS BE FAULTY? I'm cynically afraid that my next mac (notebook) will fail me as well. I earn my living with my computer. I have lost countless hours of income. Comments, please! Thanks.
