I have a Crossfire board which hasn't given me any problems before. My video card just went bad and replaced it today with a GeForce 260. As soon as I booted up, I got an error, USB device Overvoltage detected! Computer will shutdown...

I disconnected everything connected to the USB slots and still the same error. I turned off the option in the BIOS to halt on all errors and set it to No errors and the computer boots up and loads vista no problem.

I am guessing the new video card is causing the problem but not sure why it would give this error.

Anyone have any ideas? Thanks.

Did you try disabling your USB ports and see if the problem goes away. I've seen this error before, but the only time I've seen it was after a power supply had gone bad and damaged the motherboard... Its possible when your video card went out your motherboard was damaged.

Also, which card did you have before the Geforce 260. The 260 is power hungry, are you sure your power supply can handle it...

I didn't disable the ports but I removed everything connected to them. I was using a Geforce 8800 GTX card.

The computer is otherwise working working perfectly. I actually installed a new Power Supply, its now a 650 W instead of the 500W it had before. The old one is fine and I am using it on my office computer.

The fact that you're using a different power supply and still getting the error points towards the motherboard being damaged. When the old computer i was working on gave out, I replaced the power supply and got it working again, but continuallly had that USB error due to the motherboard being damaged...

The 260 would use more power then the 8800 but a 650 should be more then enough to handle it and you're not having any other problems that would point to the power supply or video card.

I also have a Crossfire motherboard that had the same issue. It happened after I disabled things in CMOS I wasn't using: USB, FireWire, etc. No hardware changes were made when issue ocurred, other than the CMOS changes.

Now, both USB ports under one of the built-in nics don't work. I guess it fried itself.
