I need help.. this is very puzzling to say the least. In 2002
I bought and put together a computer using a PC Chips motherboard
M830 series socket A and a AMD 2000+ with 256 meg of Ram and 80Gig
HD.Everything worked fine till last May 2004. I took it to a computer
service and after they tried to fix the computer (which they gave up
on) they told me that I needed a new other board. The service tech
said he could not get the OS to work and he indicated that a component
in the motherboard had shorted and that I needed a new motherboard. I
proceeded to order a replacement Motherboard from Newegg. I received
the new motherboard (from Newegg) PC Chips Socket A M848A series and
installed it in the computer. I had no problem installing the new
motherboard and the old CPU (2000+ AMD). I turned on the computer and
nothing happened. no power to anything. No fans no lights nothing. I
retraced everything and found nothing wrong. I took it as a defective
motherboard and sent it back to NewEgg for exchange. 10 days later got
a replacement motherboard. I installed it as I did above and turned on
the power. Again nothing happened. The entire unit was dead.. I
proceeded to re-install the old motherboard and turned on the power
switch. Voila everything worked, fans, HD and lights. So I took it as
another defective board. Sent it back to NewEgg for replacement got
another board in 10 days and installed it again. Turned on the power
switch nothing worked. I then left for Iraq and just returned and I am
back at this computer.What is wrong??? Please help. thanks

PCChips isn't known for having the most reliable motherboards on the planet but I doubt even they could manage 3 bad boards in a row so it would seem you are either mounting it in the chassis improperly or mis-wiring it, your retrace notwithstanding.

The 'power to nothing' indicates a dead short somewhere crowbarring the power supply so I'd suggest you meticulously double-double check the mounting standoffs to ensure they match the motherboard mounting holes exactly as it sounds very much like you've got one out of place touching the underside of the motherboard shorting it out.

Having data cables plugged in backwards, such as the IDE/Floppy connectors, can cause the same thing.

Another possibility is that you simply haven't got the power switch wires in the right place on the motherboard header so that is doesn't even attempt to turn on the computer when you push it.
