Help With Standard VGA Drivers

I'm running XP Pro SP3.

I was using a Radeon 7200 32MB card, with no problems. I recently
installed a Diamond Stealth S80 Radeon 9200SE 128MB card, and cannot
get the appropriate video drivers to install. The 9200 card displays
OK, but I can't get any drivers for it to load.

Every time I try to load the drivers I get a message box that says:

"Video Driver Not Found, Set up was unable to complete installation,
try to set up your display adapter with a standard VGA driver before
running set up."

I've done a lot of searching and tried many things but with no
success. I tried selecting the /BASEVIDEO in boot.ini in msconfig and
that did start the computer in basic video (640x480) but I still got
the same errors when trying to load the Radeon drivers.

I'm not sure if this is related, but in Device Manager: (1) there is
no Display Adapter listed (though the Radeon 9200 does appear when I
run System Information for Windows, and (2) the 'VIA CPU to AGP
Controller' shows: "This device cannot find enough free resources that
it can use. (Code 12)."

I tried to do an XP Repair and after I selected the Windows (option 1
of only 1) it asked for the Administrator password. I entered this
and it went to DOS (C:\Windows). I didn't see anything there for
repair, so I went back into Windows.

Can anyone provide a solution to this problem?
