Hi, I have a fried M2-ATX. The Q12 chip got burnt after less than 10mins in the Ampie casing in my car

I bought the M2 from Digital WW around a month ago.
Well, do you think the hardware warranty covers this situation? The 15A fuse is fine, so couldn't be a current surge right? I've tested the system on the desktop PC's ATX power supply before installing it in the car. Running it on a VIA SP13000 motherboard, 80GB notebook HDD and routed regulated 12V to Lilliput LCD display.
Any help or advice is greatly appreciated
