I recently brought my 24 in 2009 iMac to get a replacement on the graphics card. When I left the computer with Experimac, the computer was in the following state: At first the computer wouldn't boot past the white screen, but then I was able to boot it from Safe Mode and the computer was on only with vertical lines showing on the screen. Experimac had the computer for a few days before Foster called me and told me that he replaced the graphics card but it only makes the dong noise and the screen stays black. I came into the store to pick it up and asked if he can show me it boot up. He plugged it in and it wont even turn on, no dong noise either. He suggested he can give me $150 store credit towards an iMac he just got in that is for sale - same make and model as my iMac. Everyone that has basic knowledge of computers knows that if a computer turns on and works and then after bringing it to a computer shop just all of a sudden doesn't even turn on, would think twice before ever trusting this place with their electronics ever again. I can't help but think the company swapped my computer's good parts with non-working parts. The company didn't provide any reason why the computer wouldn't turn on, didn't do any diagnostic, nothing that would otherwise be in their benefit and would help them upsell and keep a customer. It is unfortunate that I cannot prove anything, but the least I can do is warn other potential customers not to put their electronics in the trust of these guys' hands.
