Hi,
I have sort of taken apart my computer and re-built it, I left the RAM and CPU in the Mobo and both the HDD and optical drive in there bays, I removed all my expansion cards (6800gt 256mb, wireless network card, 24bit soundcard, tv turner card).
I removed the PSU (antec 480w cool & quiet) and disconnected all the the power from the remaining hardware, my mobo is a Asus AN8-E, I took all the leds out also.
I then started to put everything back as I found it, the only thing I did differently to my initial build was to connect the front USB and mic where I figured they went (at the bottom right above the leds, they were in a block and I used the whole block with the 3 leads that broke down into 15 smaller adaptor in total).
I then came to power the machine up and heard nothing, I then checked all the connections, HDD, optical, CPU(which I didnt change anyways), graphics, fans, basically everything and it seemed fine, i came to boot again and theard the faintest of noises and then nothing again.
Reading back over some old threads using the search option I saw that taking the battery out and wiping the BIOS helped in some cases, can anyone give me any info on this or point me in another direction.
One thing I should mention is that I placed the PCI cards back in different places although I dont think that should cause any power problems.
Cheers

EDIT: the green light on the mobo is on but still no power.
Do the cable for the on/off leds just power the lights or the switching on process as ?
