my 4-5 year old build's power supply finally crapped out last week, and i have replaced with a corsair tx650. Receive new PSU, plug it all in, power up and everything seems fine. The LEDs on the mouse and keyboard turned on with the computer, so i assume everythings perfect. However i get no response from either mouse or keyboard when trying to log in/access BIOS. I switch USB ports, with no success. Infact, the LEDs on mouse+keyboard would only be on if you boot the computer up with them plugged into the USB port. If i try to switch ports when the computer's on, the LEDs will go off and stay off, but they would flash on briefly when i pull them out of the ports after the first swap. Very weird. I figure worst case scenario i scoop a ps2 mouse/keyboard but i certainly dont want to if i dont have to. ayudame!
