Hello everyone, I have been having issues with my computer from the day I bought it from apple (as I'm sure you've all seen from recent post) I finally got a hold of a VERY educated senior advisor at apple to help diagnose the problem. To make a long story short I sent him some system log files I had on some recent kernel panics and memory leakage problems I was having. I also sent him a .psx file of my system information and in that file he was able to diagnose I had one or more malfunctioning ram and something wrong with the Ethernet port on the logic board (I have no idea how this can relate to slow performance but some how it was interfering withing something...) anyway, he suggested bringing my computer into apple to have them run a thorough diagnostic test on the machine. They did several passes on the ram (14 or so) and everything passed with flying colors. He also ran test on the graphics card me hard drive too. Basically over the course of 5 days my computer did not show any signs of anything being wrong. So I got fed up of this and contacted another senior advisor and explained my issue. I told him how I went through every troubleshooting tip possible (including re-installing the OS 3 times) I was still having the same crappy overall performance. So he decided that he was going to schedule and on sight repair from apple and they are going to replace my entire logic board... Since that's all they can do at this point I figured why not.. So my overall question is, if there was something wrong with my computer could there still be a possibility that the test at apple couldn't have picked it up? Sorry for this issue being so broad, but I thought I would see your guys thoughts. Thanks in advance!
