USB connector shorts out board

[LPW]

Hi all,

I just put together a new machine. Asus P5B (non-deluxe), E6600, OCZ DDR2-800 2x1GB, Antec Sonata 2 case. It all works together quite nicely, except that I cannot plug in the front-side USB ports to the motherboard. When I plug in the connector from the case to the motherboard, the system won't post. Instead, it powers off, and then powers on again, with the Blank Screen of Death. More precisely: After pushing the power button, the fans (PSU, chasis, and video card) spin for a while (6 seconds or so), then shut off for some 2 seconds. Then they all start spinning again, but there's no ghost in the machine. No video, no beeps. If I disconnect the front-side USB ports, everything is fine, the machine posts, boots, and kicks ass.

I'm using the latest BIOS (0309, 8/14/2006).

Any ideas?

Thanks,
Lukasz

P.S.
No, I'm not trying to plug the 1394 port into the USB connector. 😉

are you 100% sure you got the wires in the correct order? didn't mistake a 5+ for a grnd? they are a pita and sometimes accidentally put them in the correct order due to the way the m/b illustrates

yepper. Make sure you have set up the wires properly.

should be hooked up like this

If it is and you still have the problem then maybe there is a problem with the front ports themselves.

I think you have flopped the USB Connector 180 Degrees

On your MOBO, no matter which UBS Header you are looking
at (your board has 3) ... the RED Wires from the USB Jacks
should be facing the BACK of the Motherboard ... this is the
side of the MOBO that faces the rear of the computer case
