Why don't you repost this in the Ask dmaxalliTech forum tomorrow. When Eric gets back from vacation I'm sure he would have some input on this. This sounds like a very odd failure and the fix sounds odder. I'm wondering if this dealer isn't just throwing parts at the problem without really knowing what's wrong. Let's face it 1 computer fails okay. 2 Computers fail??? HUH?? Either something is damaging them or the dealer doesn't have a clue. Either way they aren't fixing it are they??
