I have a machine here with that MB and processor combination. I also have an Asus 9800 Pro card. I successfully installed W7 32 bit on it just about a year ago. Here are some suggestions from my notes:
I installed W7 SP1 by creating a slipstream install disk. This greatly improves the odds of a good install. And saves a lot of time with updates too.

If you are going to install SP1 from WU then you must install this alone. It is very important to be patient and wait for the install to completely finish after the restart before touching the computer. This can take up to 30 minutes. Wait for all hard drive activity to slow down/stop.
The list of Windows Updates to install afterward is massive. It is not a good idea to install these in large batches. What I do is install them by starting with the oldest updates and installing them in batches by month (all the updates from Jan 2011), and further by installing them by type: Security, Update, ActiveX, Explorer, .NET .
This is tedious, but avoids the problems (and performing System Restores) that occur when updates conflict.
The motherboard is old and the on board devices do not have W7 or Vista drivers.
I actually found that the drivers for these devices offered by Windows Update worked best to get functionality and stability. Any non original Asus drivers I found did not work well. Some drivers would only work if from WU. Particularly graphics.
The AD1985 audio chip on the board uses a driver that is too old to use in W7. I only recently starting having problems with the audio drivers and bluescreens after installing tuner cards in the machine. I am pretty convinced I am going to need to upgrade my audio hardware and disable the on board chip and remove those drivers from the system.
In your BIOS settings you should check to be sure you have 2 changes made from the defaults:
- Advanced Tab > USB Configuration > USB 2.0 Controller Mode > should be HIGHSPEED.
- Power Tab > ACPI 2.0 Support > Should be ENABLED
Hope that helps
