Defect Acer Aspire 9301AWSMi

For about a half year ago, I wrote a topic, on this side, concerning a defect Acer Aspire 9301AWSMi. Back in June 2008, I contacted Acer to get support on my product, which i bought back in March 2007. It was sent to their repair facility in Germany (I live in Denmark), and they returned the conclusion, that is was a water damage. After i got the pictures form Acer, to show evidence on this water damage, I decided to return it, without being repaired. They wanted to replace the motherboard and keyboard to a price of apx. 400 euro.
About a month ago, I finally succeeded in disassembling the computer, due a damage Acer has made on one of the screws. I examined the hole chassis and motherboard, and concluded that there has been a tiny drop of water on my chassis, but my motherboard looked perfect. I found out that Acer had resized the picture massively, so that the damage looked bigger than it was.
I called Acer support, to clear this problem by getting the proper evidence. First I heard the staff member read something on English, written by the man who repaired my computer. After that, she said that there was not such a document, because it has already been deleted. The case was closed, but I haven’t got any note about closing this case.
I have several times tried to clear this problem out, but without luck. After my own examination of the computer, I think it’s not the motherboard which is defect, but the processor, since there is power going on the motherboard. A new Athlon 64 x2 processor only costs 40 euro, which I would be willing to spend if that’s the problem (original processor is an AMD Turion 64 2.00 ghz). Would that conclusion be plausible?
