Building a pc...not booting

[blackrain]

I just put together a pc with a refurbished asus CUSL2, my old celeron 400 (which will be upgraded to my celeron 1ghz once I do the bios update if needed), and an old stick of 128 mb ram.

i'm using the onboard video but have also tried a separate card.

The green indicator/LED on the motherboard comes on when I plug in the power and hit the on switch on the psu.

Nothing happens after that. The fan on the cpu spins okay. the HD turns on. However, there's no speaker beeps etc. Monitor remains off.

the cpu was working when it was last used. I had upgraded so it went to storage. Same with the ram.

I am using an antec 300W smartpower psu. It has a 12V connector which isn't being used on this board. Is this psu okay to use with this board? One time I forgot to plug in the 12V 4-pin connector on a pc and nothing happened until I plugged it in. Is this the problem here?

psu should be fine, there is no 12v connector on a p3 system so that shouldnt matter

try
1) resetting the bios jumpers
2) re-seating the cpu
3) check the mobo is not contacting any metallic parts and shorting them out (eg. screws too tight, or screw mounts that touch from the bottom)
4) check the video card, if its agp8x it may not work as 8x=1.5v ....2x & 4X =3v (IIRC?)
5) try putting the ram in a different slot

if anything is dead, its probably the mobo

1) Not sure what you mean by reset the bios jumpers. It's set to jumperless.
2) Tried reseating the cpu
3) Checked the mobo...loosened the screws
4) It has an onboard vga...tried both that and a pci video card
5) Tried ram in the second bank (I thought you couldn't do this by the way)

Nothing worked.

This board doesn't have a jumper for resetting the cmos so I uplugged the power and pulled the battery...didn't help either.

This motherboard has chassis intrusion detection. Is there a jumper on the chassis intrusion leads? if there is no jumper there you will not be able to boot. The light between the PCI slots only tells you that the MB is getting power, not that it is running.

You are using onboard video? And you said you tried another graphics card..

Did you disable the onboard when you switched cards.. Do you know what the Asus board was repaired for?

There's a jumper over the chassis intrusion

The manual doesn't say anything about hardware disabling of the onboard video...i assumed you could only do it in the bios. I've looked in the manual and don't see anything in the hardware setup.

Regardless, if the onboard video is bad, then the mobo is probably not going to work.

Have you looked in the BIOS to see if there is a way to disable the BIOS.

Also, if you do not have a keyboard plugged in, it will not boot up. It will just sit there saying that no keyboard detected. This will not show on the monitor if it is the first time starting up the computer. I had the same thing happent to me.

I'm confused...how can I look in the BIOS if the pc won't POST.

When I plug in my monitor into the VGA port, the light on the monitor turns yellow. Typically, when a pc boots (POSTs), that light on the monitor turns to green. Well let's just say that the light stays yellow when I turn on the pc. Fans are spinning. Green light is on the board so the board is getting power. HD churns. There are no beeps.
