Asus Deluxe SLI Mobo - USB Over Current Status Detected, Computer will shut down in 15 secs

This computer worked just fine since last Christmas, until my son moved it downstairs and hooked it up. I looked everywhere and ensured all is plugged in, etc. The error still persists. I cannot boot to a floppy or CD, nor can I get into Bios.

Should I try taking out the battery and reset CMOs (how do I do that?)? would that help? I have a 500 watt Ultra power supply, works great. However, I went to their website and noticed that they have new SLI compatible Power Supplies. Would that make a difference?

Thanks in advance!

Have you dissconnected all usb devices.

>>  USB Over Current Status Detected  <<  what devices were running on the USB ? if it was a disk drive, without external power supply, it may have caused it. - and once you have it, if the cmos reset (or a bios flash) does not cure it, i know of no way to reset it.
Do you have the error with ALL usb devices removed?
If your speakers are USB, they will also draw a lot of power...try connecting some mains powered speakers instead...

I already tried disconnecting all USB devices, including other accessories (i.e printer, lan). The error still remain.
can you answer to all our questions, so as to give enough info for further help ?
As i did with yours
Reset the bios as nobus has suggested if you still get the error i would say the usb controller is freid and the motherboard will need to be replaced

I had to remove an unused card that has some USB on there. It solved the problem.
