I recently upgraded 2 PCs to Windows 7. Both of them are clean installs. 1 of them I used 32 bit (4GB RAM), the other 64bit (6GB RAM). They both have the Realtek High Def Audio sound cards built in. on the 4GB PC, Windows uses its OWN High Def Audio sound driver, which works but sounds like crap, no dept, no bass. On the 6GB PC, Windows 64 FOUND the Realtek High Def Audio sound driver so it sounds great. I have tried on the 4GB PC to install the Realtek High Def Audio sound driver (from downloading it) BUT upon restart Win7 reverts BACK to its own High Def Audio sound driver, which drives me nuts!!! I have tried disabling it and removing it before installing the Realtek High Def Audio sound driver but upon reboot it always goes back to the Windows driver. The download is an executable (and runs w/o creating a folder) so I can't point the Win driver to it. Help!?!?!?!?
