Trouble-shooting a DOA carpc
Howdy, I purchased the carpc mentioned here: http://www.mp3car.com/vbulletin/classified-archive/47646-car-pc-for-sale.html
I received the package, it was excellently wrapped, and my god is it pretty! Problem is, it doesnt work...
Symptom: No beeps or display, no keyboard lights illuminating
Procedure: I simply connected a mouse, keyboard, monitor and power. When i flick the power switch on the power supply, nothing happens. When i press the power button, the system fans start up and the hard drive starts spinning. Thats as far as it goes. Nothing else happens
What I've ruled out (in order):
Ram - I tried reseating the single chip of ram. I tried putting it into the other slot. No change. I replaced the single chip with 2 known good. No change.
PCI devices - removed
ATI card - removed and tried on-board, no change, reinstalled
Hard drive/IDE cable - I tried a different hard drive and cable. also tried the other channel. No change
Processor - Cleaned the processor and swapped it for a known good. Processors work in secondary p4 machine, but no effect on the one having problems
Power supply - swapped in a known good and no change.
So that leaves the motherboard. Does anyone have any advice? The seller seems like a good guy, I just hope i wasn't sold something that is broken. Anyone know how to troubleshoot a PC CHips mini atx motherboard?
