i brought a compaq 157123-102 motherboard (could be a oem version of the mitac 6513wu motherboard) with a p3 1.0 gb processor off ebay. i put memory on it connected my keyboard, mouse
and monitor to it (it has onboard video) turned on the power, the cpu fan spins but it will not post. do i need to put it into a case to test it, nothing at all appears on the screen. could it be that i need to connect the front case power conection leads to the motherboard for it to post.
