System hanging at "initializing USB" post message

[pjladyfox]

Everyone,

Okay, I'm at my wits end on this and I'm hoping some of you may be able to help to try and trace a possible power supply routing issue.

To start from the beginning, I was impressed by the Project: Lupine case mod so much that I purchased a Centurion 5 and sent it to MNPCtech to have the following done:

a. A routing hole, lined with a rubber gasket, so that I could route the power supply cables under the motherboard.

b. To have a window cut in the side panel.

c. A custom paint job

So, I got the case back and proceeded to add my hardware in; routing the power supply cables under the motherboard and sealing everything up. Problem is that, for reasons I can not fathom, the system is hanging at the "initializing USB" post message and will not proceed further.

Now, I know that the hardware works since all the equipment came out of a working system with the only new addition being a Asus A8R32-MVP Deluxe motherboard. So, my instincts tell me that it has to be something to do with the power supply either grounding out or a cable is being pinched somehow.

I had the system posting and booting into the OS with the side-panel off the first time I routed the cables. However, it was intermittent and would occasionally give a rapid-beep error during post at the "initializing USB" message.

For completeness, here is the hardware I have in my system:

Cooler Master Centurion 5
Silverstone ST60F 600W power supply
AMD Athlon X2 +4200
Asus A8R32-MVP Deluxe
Patriot PDC3200LLC 1GB RAM (count: 3)
ATI Radeon X1800 XT + X1800 Crossfire in Crossfire mode
Asus DVD burner
120GB Seagate SATA2 drive
300GB Seagate SATA2 drive
300GB Seagate EIDE drive (count 2)

Help???

Did you plug in the case USB headers to the MoBo? If so, try unplugging them and booting.

Unplug all USB devices from your computer and see if you can POST without them.


I would try removing all your parts and attempting to boot outside the case to eliminate the possibility of a short somewhere in the case.

You could even try disabling the usb ports in the bios.

Everyone,

Thank you VERY much for all the help. It turns out after fighting with this for another couple of days I found the root cause: the first two memory slots were bad.

I was extremely lucky that they did'nt take the 1GB modules I had in them. No wonder the person who I got the motherboard from was so eager to get rid of it. Oh well, at least it's still under warranty so off I go to RMA this thing.
