my new pc is almost done. only need a hdd, so i decided im gonna take out the hdd (primary, the one w/ everyting on it...windowxp is preinstalled on this hdd) in my comp. im using to type this up, and put it in the one im building to see if it work.....it didnt. w/o the hdd, it would boot to the bios, but w/ the hdd installed, it would turn on, power up and everything but the screen is blank, and the monitor indicator light is yellow (not active). i checked the jumper on the hdd and everything is right. but one other odd thing is when i turn on the power, i dont get any lights from the led. the comp led dont light up and the hdd led is the same. what am i doing wrong.
