Carputer randomly booting up

Hi.

I just got a new epia 2ghz to replace my fried 1ghz mobo. I am using an m2-atx, and have the new system running, but with a very bizarre problem. It will randomly boot the computer after I've walked away. Even more bizarre, it seems to be related to when I lock it with my key fob. If I dont lock the car at all, it will boot itself within a few minutes anyway.

I have done a bit of power button modification. The green/white wire from m2-atx to the mobo is normal. The acc wire from the battery to the m2-atx has a flip-switch in-dash so when it's off, the computer wont boot (for very short drives). In addition, the wire from the power button on the case has been hacked, I spliced on an additional button which is also in-dash.

When I used the 1ghz mobo, everything worked exactly as I wanted. Now that I've installed the 2ghz mobo, the carputer boots randomly! That it happens exactly when I lock the doors befuddles me. I haven't done full testing on rig because I finished installing at 2 am. But I do know that the power buttons both in the case and in the dash are fully functional.

Anyone have any ideas?

Must have been interference along the power switch splice. I pulled that button out, from the button all the way back to the splice on the headers and that solved the problem. Very weird interference, though. It was more than just with the key fob. Anytime the doors locked or unlocked it would send a button push.
