Need help with Vista clean install with raid

I have a dimension 9200 running vista home premium. It has 2 x 320gb hdd running in raid 1 configuration. I am running the latest bios for this pc (v2.5.0).

 

I made the mistake the other day of installing the latest version of intel matrix storage manager (v.7.5.0.1017). It required vista reactivation by phone (which worked) but corrupted the Windows Genuine avantage files on my pc. On bootup I was getting a message that I did not have a genuine version of Vista.

 

I spent 2 hours on the phone with microsoft. They confirmed important WGA files were missing. Eventually they got me to do an inplace upgrade to repair the WGA. The upgrade failed (twice).

 

At that point my only way out I believed was to clean install Vista (my pc was originally xp and I use the express upgrade disc).

 

Last night I clean installed vista 3 times with the latest storage manager software and each time it corrupted WGA.

 

Eventually I found the previous version of Intel's matrix storage manager (v7.0.0.1020). While that didn't corrupt WGA it conflicted with Itunes and has been causing BSOD every time I try to run Itunes. Apparently this is a known problem. These BSOD's corrupted my RAID array and the Intel storage software has just spent the last 2 hours verifying and repaing the drives.

 

So, I'm getting pretty desperate. I want to clean install Vista and fix these problems but I must be doing something wrong. This is what I have done:

 

1) boot with vista cd and select custom

2) format drive0 (my raid drive)

3) let vista grab whatever drivers it needs from the internet

4) When the clean install is finished and boots for the first time I install the intel storage console.

 

I don't touch the bios.

 

I think I should also load the intel matrix storage driver at the screen where I do step 2? I haven't done this but I think it is the console installation that is causing the problem anyway. 

 

Can anyone who has had success in installing the latest Intel console please give me a step by step guide as to how to clean install of vista so that the storage console doesn't corrupt WGA?

 

Any help appreciated.
