Unable to load the CMOS settings.

July 25, 2011 at 23:47:50
Specs: Windows XP, AMD x2-250/2GB DDR-3
I've purchased and assembled Asus M4N68T-M LE v2 motherboard along with AMD x2-250 processor. When I started it, it displays the following message:
"Please enter setup to recover BIOS setting
USB Device Over Current Status Detected !!
System will s--- Down After 15 Seconds"

I'm unable to boot the system or view CMOS settings. Please help!

Check if all USB jumpers are in correct place (use the board manual to see board diagram).

The only motherboard jumper you need worry about is the CMOS reset jumper. That may be in the reset position which will stop the motherboard from starting up correctly. You need to put it into the run position,

You will need to re-enter the BIOS setting. Press whatever key combination is required, usually Del. Set then and Date and any other required settings. Save and Exit and Reboot.

If CMOS jumper isn't in correct place the system will not post.

The only motherboard jumper you need to worry about is the CMOS reset jumper
The other important jumper is OC jumpers(if not set correct the system will not post or unstable or post but unable to boot).

Isn't that exactly what is happening. The system cannot complete the POST without valid information in the CMOS memory, that is the BIOS settings.

Hey guys,
Thanks for the post. I went through the manual, there's a mention of CLRTC (Clear RTC RAM) jumper. Is it the same CMOS reset jumper?

"USB Device Over Current Status Detected !!"

Clearing the Cmos WILL probably NOT cure your problem !

Your problem is probably caused by the wiring of one or more USB ports on the case and the USB header on the mboard NOT being compatible with each other !

Or - the same applies if you're using a USB wiring adapter that is two or more USB ports in a plate that you install in a slot space on the back of the case and wire up to a header on the mboard.
If it did not come with the mboard, it's wiring may not be compatible with the USB headers on the mboard..

There are two possible uses for a fifth pin for one USB port on the mboard header, and for a fifth wire coming from a USB port on the case - Over current, or a second Ground.

If the use for the fifth pin and for the fifth wire coming from the case ports are different, you will get the Over current message from the mboard's bios, even when nothing is plugged into the mis-wired USB port(s) !

You must connect the USB port wiring to the mboard header such that the fifth wire is not connected to the fifth pin on the header.

Asus mboards have one or more headers that are for two USB ports - a two row header, 5 pins on one side for one USB port, four on the other side for another USB port, a pin missing in one corner.

E.g. If the case USB port(s), or the USB wiring adapter that is two or more USB ports in a plate that you install in a slot space, has

- individual female connectors for each wire for a USB port, DO NOT connect the fifth wire for a port to the fifth pin on USB header on the mboard !

- a 4 in a row and a 5 in a row one piece connector pair for the USB ports, a wire in each position, assuming the wiring is otherwise compatible with the wiring of the pins on the USB header, plug the 4 in a row female connector into the 5 pin side of the mboard USB header such that the fifth pin is not connected, plug the 5 in a row connector into the 4 pin side of the mboard USB header such that the fifth wire is where there is no pin on the header.

- a one piece female connector, two row, 9 pin holes, one pin hole is blocked in a corner, assuming the wiring is otherwise compatible with the wiring of the pins on the USB header, you must cut the fifth wire on one side of the female connector (that is for Ground or Over current.)

- two 5 in a row one piece connectors for the USB ports, a wire in each position, assuming the wiring is otherwise compatible with the wiring of the pins on the USB header, you must cut the wire in the connector ( that is for Ground or Over current.) if you plug it into the 5 pin side of the USB header, or if you have enough headers, plug in the 5 in a row connector into the 4 pin side of a USB header so that the fifth wire is not connected.

Thank you all guys!
The problem is solved. Actually, it occurred due to nuts on the cabinet... The vendor suggested the same and said, it's a common problem... Thank you all again for your valuable solutions... :)

Thanks for the Thanks.

Nuts ?
Most computer cases have no nuts at all.

Did you have one or more loose screws that were shorting something ?
Or - did you have a case metal mboard mounting post in a place where there was no matching mounting hole in the mboard, and that was shorting something ?
