Keyboard not detected

I just bought and put together my first computer. All was going well until I tried to boot up, and even that was ok :) 

I'm not sure if I missed something or if it is a motherboard issue, but when I turn on it goes to a boot screen and tells me there is no keyboard detected. My mouse and external DVD Drive are detected, but no keyboard. Both the mouse and drive are USB, where the keyboard is the old connection (not sure of name). I don't know why it isn't being detected, I have tried multiple keyboards with this input style, all to no avail.

If anyone has ideas please pass them on. I don't think there is a connection I missed because that receiver goes straight on the MB.

If it will help here are my system specs:

MB: ASUS M4A78 Plus AM3/AM2+/AM2 AMD 770 ATX AMD Motherboard

Video card: SAPPHIRE 100245L Radeon HD 4850 512MB 256-bit GDDR3 PCI Express 2.0 x16 HDCP Ready CrossFire Supported Video Card

PSU: OCZ StealthXStream OCZ700SXS 700W ATX12V / EPS12V SLI Ready CrossFire Ready Active PFC Power Supply

CPU: AMD Phenom II X2 550 Black Edition Callisto 3.1GHz Socket AM3 80W Dual-Core Processor Model HDZ550WFGIBOX

RAM: OCZ SLI-Ready Edition 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model OCZ2N800SR4GK

HDD: Western Digital Caviar Black WD1001FALS 1TB 7200 RPM SATA 3.0Gb/s 3.5" Internal Hard Drives

Any ideas are appreciated!

Hi.

The "old" connection is PS/2. See here: http://en.wikipedia.org/wiki/PS/2_connector
Maybe you plugged the keyboard in the mouse connector (they are not interchangeable).

Other things you can try:
1) get a PS/2 to USB adaptor (http://bargainhopping.com/cart/images/ps2%20to%20usb%20...) and plug the keyboard in an USB port instead.
2) check if in BIOS the PS/2 support is disabled. I don't think it is, since PS/2 should have native support, and you can usually enable/disable the USB mouse/kb support in BIOS, but it's worth a try.

You built a decent rig. Why not drop $5 on a generic USB keyboard to see if that fixes you up? Time is money!

I can't get into the BIOS because of the boot up error screen. I will be buying an new keyboard today. It accidentally posted this thread twice and I posted more info in the other one.

I am also getting a USB Device Over Charge Status Detected !! warning

Any ideas in that?

Thanks for the help everyone, I got a USB keyboard and it was recognized and to solve the overcharge I pulled the MB and found that I had put in an extra spacer.

Thanks everybody
