Biostar M7TDR P4 Motherboard willnot start

. I do however have another motherboard that i bought and can't even get it to turn on...No light on keyboard or motherboard, no fan movement.
The motherboard is called Biostar M7TDR P4...Socket 423
I used one stick of 512 mb 100 mhz memory like the manual siad.It siad 64 to 512 in each slot up to 1.5gb......
But when you turn it on nothing happing.
I used the same power supply I had my last P4 mother board in. it has all the power connection. ATX...The extra 12v connection and the extra 5V connection for CPU.
Nothing is happing. it doesn't even start.
I even took Cmos Bat. out for an hour to reset Cmos.
I have move Cmos jumper to pin 1-2.....and 2-3( Normal and clear)
it is suppose to be a band new board.
Any help would be great.
Thank Alvin

Do you know if the CPU is good?
Does the heatsink get warm?
Have you connected a speaker? If so, does it beep?
Remove ALL drives, cards and boards except one stick of known good ram of less than 256mb and a video card if there is no onboard video.

The CPU is good I know because I pull it from a working computer.
The headsink I didn't feel to see if it was warm.
I didn't hook up any speaker wire. but will do that today.
Will post and let you know.
Thank again.
Alvin
