i am thrilled to report that after nearly three weeks without a computer i once again am back online in a normal fashion. after finally getting the second part in and replacing it on my computer, it was determined that the repairs didn’t fix it and they had no idea what it was. so they gave me a new computer. so now i have an upgraded processor, video card, larger hard drive, better dvd burner and the LED backlit screen. super excited about it. i have forgiven apple for putting me through the last two weeks because they have definitely made up for it.that is all. for now.
