There are no error messages during the post. Communication with the Bios is not possible since it does not recognize any device attached to the USB ports. The computer does continue to boot up to Windows XP.
I have attached known good keyboard and mouse.

Please update all the bios, chipset, motherboard, bios, and all the drivers that your computer have.  Also go to and downaload all the windows updates including SP3.  All that should be current.  Even if you have the bios updates install the latest one to overwrite any faulty or corrupted chips.  

Good luck.
Lostinak, the bios might be tricky,  you need to keep in mind that the usb devices send a interrupt request to the bios to tell them that they are there.  If the Bios doesn't get it, it thinks that there is no USB devices.  If there is any communication errors then it might not recognize that they are there.  Please install all the drivers and Bios and go from there.  

If you have another tower similar to the one you have,  you can put the hard drive and test any usb device.  If it works I am right, If it doesn't then it is an OS problem and formating might be your solution.  Good luck

I apologize lostinak I was tired and didn't put 2 and 2 together that you couldn't access the bios.  Punky... I didn't know they made that piece of hardware.  Good to know.  Thanks!
