i am trying (note TRYING) to upgrade my pc. so i installed a 300gb harddrive (maxar), Epox series 9npa nForce 4 ultra motherboard, AMD athlon 64 and a Radeon x550 graphics card. the PSU in an Antec 480 volts (reused) and the (reused) cd/dvd rw is connected through an old, reused analog cable. (or somesuch.) it seem that i have everythig connected as it should, and when i plug in a moniter, and power up, all fans whir, little blue LEDs light up on the motherbord and a little 2 didget display on the motherboard says "77". all is fine. or so it would seem...... none of the oncase LEDs light up, (i am using an Antect sonta), the CD drive wont do anything, and although i dont have XP installed yet, i cant see the BIOS onscreen. and i would sort of like to be able tto see the BIOS.... any idears? i shall take all abuse in my stride, as i accsept that i probibly have done somewat stupid. PS. i dont have a clue what fourm to put this in since i dont know wht is going wrong, so i put it in this one. someone shout at me if i am wrong. im a big boy. i can take it.
