I thought my EPIA 5000 died, but it turned out the problem was in the power supply connector. One of the cables of the ATX connector was not soldered very well and this caused the board to work on and off. I guess there is a good power protection on the board, because it didn't burn, but works as new.

I ordered a new board before I found the real problem, but having one more EPIA around is not bad at all. I'd be able now to test my software before I download it on the car PC.

I want to thank all people that sent me emails asking to become beta testers of my software. I really appreciate your will to help me out with this task. I will make a link on my page, where you can download the latest release for beta-testing, as soon as I have something that I think is good to be called a release candidate. Thanks again guys.
