Could be that your system is hanging while trying to detect something.
I have the same motherboard, and I had problems even entering the WinXP setup. For some reason, the onboard USB chip caused the setup to hang upon entry.
Try going into BIOS and changing the onboard USB to 'disabled' and then finish installing Windows. After you boot up for the first time, go back into BIOS and enable the USB (1.1 + 2.0) and then all should be fine.
Plus you'll get some practice navigating without a mouse using Tab and such
