USB Enabled in Bios - Win 7 Won't Start

I had WindowsXP SP3 installed on this home made desktop and everything worked fine. I formatted the drive to install Windows 7 Home Premium.

1-I had issues installing, it kept getting stuck after the install at the "Starting Windows" screen so I disabled USB in the bios.

-Now everything works great but when I re-enable USB it freezes in the same place.

-Taken out RAM and tried different sticks.
-Tried disabling the floppy and other drives
-Updated the bios

Any other ideas?

ABit KX7-333 Motherboard

AMD Athlon XP 2000+ @ 1.67 Ghz (I actually think that this is an XP 2300 or 2600 chip, that the motherboard is just running like a XP 2000+ chip)

All-In-Wonder 9600 TV Tuner
and Graphics Card

1.75 GB PC 2700 RAM (4-DIMMs)
Plextor DVDr Drive
Linksys Internal Gigabit Ethernet
60GB Primary Hard Drive
250GB Secondary Hard Drive
3.5” Floppy Drive

The motherboard isn't listed at the Windows compatibility site: Windows 7 Compatibility: Software Programs and Hardware Devices: Find Updates, Drivers, and Downloads

You might try this driver: ftp://ftp-usa.abit.com.tw/pub/downlo..._chip/v456.zip
And install it using compatibility mode for Windows XP according to these directions:

Compatibilty Mode Driver Installation:
1 - Download the latest driver from the manufacturer's website.
2 - Uninstall the current drivers using the Control Panel...Programs and features...Uninstall a program applet. Then verify that the driver/device has been removed in Device Manager
3 - Right click on freshly downloaded driver installation file and select "Properties"
4 - Select the Compatibility tab - and do the following:
- Click on the "Change settings for all users" button
- Click on the box to select "Run this program in compatibility mode for" and then select Windows Vista Service Pack 1
- Click on the box to select "Run as administrator"
- Click on OK to exit all the dialogs
5 - Right click on the driver installation file and select "Run as administrator"
6 - Let it install and see if that stops the BSOD's.

If it doesn't work, you'll either have to avoid using the USB, or get a new motherboard.

If the drivers don't install, and the board isn't listed as Win7 compatible - then it would seem to me that the solution is to purchase a Win7 compatible mobo.
