Asus Mobo - USB Over Current Status Detected...

Specs:
ASUS P8Z77-V LX LGA 1155 Intel Z77 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard
Intel Core i7 Sandybridge 2XXXk Processor
Antec High Current Gamer Series HCG-900 900W ATX12V v2.3 / EPS12V v2.91 SLI Certified
CrossFire Certified 80 PLUS BRONZE Certified Active PFC Power Supply
8GB Ram DDR3
Onboard Video & Audio

So my project yesterday was to swap computer cases. After completing the swap, i turn on the computer and i get this error message: USB Over Current Status Detected, System Shutdown In 15 Seconds.

During the startup process, i'm unable to enter the bios - actually, no keyboard input is accepted by the cpu during post (using ps/2 keyboard).

I've read that the usb ports on the front of the case could be bad/ shorting out, which could cause this senario, however i have nothing connected to the board besides power, DVI cable for monitor (not even hdd). Can anyone shed some light?

  1. Okay, so im going to say that thier is somthing wrong with the USB Connector... try unplugging the Front Panel connectors that you have plugged into your motherboard
  2. Appreciate the response, again, there is nothing plugged into the Mobo besides power, dvi and ps2 keyboard.

    I should also add that the mobo is still in the case. i will be taking it out tn to try and start it.
  3. Oh, so the front panel USB ports/Audio are not connected to your System? hmm...I Not to sure about this but maybe your USB ports contacts are touching each other causing overcurrent.

    take at look at this post: http://www.tomshardware.co.uk/forum/314200-30-device-current-status-detected-shut-seconds
  4. Thanks again for the quick reply. Unfortunately, i've read through most of the threads on this site corresponding to my problem, and most of them seem to diagnose it as a malfunctioning or broken USB hubs on the front of the case. that is not the case here.

    I guess i will have to take everything out of the case and try to start it up on something non conductive.

    Also i was told that there is a bios recovery utility on the Mobo driver CD. I will try to run that utility as well. I will post back with that i find. Thanks again.
  5. best of luck, i'm interested to see what the problem is
  6. So the computer booted successfully out of the case. Gonna check the case and blow everything out before reinstallation. I'll report back...
  7. Must be a short somewhere I guess.

    The other thing that sometimes causes this is when a self powered USB device or hub is used. THere are a lot of devices out there that are non-compliant with USB spec, and have DC on their input. IF there is DC present on the input of a self-powered device it can give rise to errors like these.

    Two main sources of short-circuits when you install inside a case:
    - that metal I/O panel at the rear of the case. It has "Tabs" which often slide INside the USB connectors instead of outside, just touching the metal housings of the USB connects.

    - the metal motherboard stand off's. Count the # in the case and the # of holes in the motherboard (answer is usually 8 or 9) make sure they all align. Make sure the heads of the screws you use are small so they won't overlap traces on the motherboard.

    Im not sure if it was the back I/O panel or just the case in general. I disassembled and reassembled the cpu twice, with teh same problem, so im going to have to say it was something in the case touching the board where it wasn't supposed to.

    I eventually went down to my local MicroCenter and bought a new case, which worked seamlessly.

    Thanks guys and gals..
