When I shut down my PC, The USB's and the PS/2 is on and the leds are lit up like a Christmas tree. I done some googling and it appears that their is an option in the BIOS to disable the power on USB's when the PC is off but I'm not to sure what to look for. There are a few USB options and nothing on Google is clear on what option I need.
The latest BIOS contains all previous fixes - i.e. it does NOT work like, for example, Windows update. The BIOS utility is a small DOS program used to flash BIOS. You can run DOS programs from a USB drive - check our articles.

Still having an issue.
I followed your article about running dos program from USB but instead of copying ES Tool, Added the BIOS update .rom but it only takes me to DOS. I cannot start the BIOS update. I have tried "run" "setup" I renamed the BIOS file to ASUS.ROM and it wont do anything when I type that in either.
Although it's not generally recommended, I've twice updated my Asus M2N4-SLI BIOS from Windows with no problem - I do hold my breath whilst it updating though. It's your final choice though, no guarantees
If pressing your power switch doesn't immediately shut down the PC The motherboard power must remain connected to activate the ATX power supply.If power still comes on, try the last adapter you removed in different slot
One thing that comes to mind .. if you have "enabled" power on from keyboard, mouse or any of the other currently standard option, you will need power to those devices. The Power is fed from the 5Volt Standby voltage which is always on until the main switch is thrown .. disabling these features might help you. My Asus always leaves power to my optical mouse, which I find quite helpful, since I always check my room as I am leaving, turning the light off, so the glow from the mouse warns me to turn of the main switch on the multiblock. This kills power to everything including my wireless router.
