I have upgraded a Dell Optiplex GX280 to Windows Vista successfully, however I cannot get a couple drivers to install correctly. First off, I have no idea why, but I was able to install the SoundMAX audio driver perfectly fine on the first time I installed Vista (I had to reinstall with a bigger hard disk), and this time I have to manually run the setup program and it comes up with "The audio drivers do not support your computer hardware". I have tried rebooting the machine multiple times and still get the same result. Driver I use: http://support.lenovo.com/en_US/detail.page?LegacyDocID=MIGR-68015 The other issue is the video driver. I have AMD Radeon X300/X550 Series (as stated by the machine. The graphics chip doesn't have any label on it whatsoever as far as I have seen), and it is currently using the Microsoft version of the driver. That's fine and dandy, but all it does is run the basic functions and I can't get the TV output to work. So downloading and installing AMD Catalyst automatically gives me the correct driver software. All goes well until it starts doing the Install Manager, it says "Application Install: install package failure!". Here is the log that it comes up with: http://puu.sh/8HyCq.xml ... I am still downloading updates (still in SP1 at the moment), so that might explain the video driver problem, but that doesn't explain why the sound driver suddenly won't work. One thing to note: I know this isn't the best machine to be using, but getting a better one is not an option at the moment. I deal with what I have.
