I have Windows XP (which I usually LOVE) on my HP Pavilion a820n desktop computer. I recently had to do a reinstall of XP, due to removal of an anti-virus software which (apparently) corrupted my computer. After doing a clean full reinstall of XP, some of my drivers are missing (most notably, my Audio driver). I went to the HP website, but their software could not scan my computer (apparently not XP friendly). So, I tried to do a manual installation of the driver - not an Update - the actual driver.

It will not install. I don't know what to do! Please help.
