Via Epia M10000, Opus 150

After hitting a bump while driving my carputer just shut off. After thinking it was my motherboard that shorted, i went and got another mobo. Same problem.
So, the mobo is not the problem. The opus lights up green as if its on but the cpu fan or screen doesn't turn on.

is the fan inside my Opus 150 DC/DC supposed to turn on? The light on the opus turns on but the fan doesn't run. Is that normal or is my Opus the problem?

I checked and double checked the power switch and the cable that connects to the mobo. is there anything else i can try?

Thanks again guys, i really couldn't have done this project without this forum.
