Hi! First time poster looking for a little help. I'm building a system around an Intel DX38BT motherboard. I was able to install XP fine. After I installed the MB device drivers and rebooted, the USB ports became unresponsive. I can get into and manipulate BIOS fine, but once the bootcodes disappear it seems like all the USB ports lose power - the numlock on the keyboard and the laser on the mouse go out. Windows boots, and hitting the power switch causes Windows to initiate a shutdown, so the system isn't locked. I've tried the following:
- Booting from the DVD drive - system doesn't respond to KB at the "Press any key to bood from CD" prompt.
- Tried all available USB ports
- Removed all non-essential hardware (including FP USB ports)
- Reseting BIOS to "Optimal" settings
- Resetting BIOS using the HW jumper
- Removing all hardware and reseating the motherboard
- Replacing the CPU (longshot, but I was getting desperate...)
- Removing the hard disk on the off chance USB drivers loaded *very* early
- Booting from a USB drive (yea, I thought it was pointless too, but again...)
