correct me if I am wrong Allan, just don't make derogatory comments. just wanna help. this is what the forum is all about, right. quote: "If you have some solutions, register and help others. Unlike many "Help Boards", we welcome input from well informed and well experienced members, not just moderators." a bullet in the forum 'read me.' I am open for other suggestions. again, forum. open. let us learn. I will be glad to learn from everyone especially tenured members. 
ok
yeah. you partitioned your HDD and instead of reinstalling Win 7 you installed another one, not to mention, the unfinished Win XP installation created an option on the OS menu prior boot.
Sounds right to me
do an OSRI either XP or Win 7, but got to delete all partitions. this would delete all files in the HDD and get a clean OSRI.
What's an OSRI? best I can guess is "Operating System Repair Install" but the context suggests a clean install, in order to delete partitions. This is probably what confused Allan
regarding the equalizer and/or subwoofer settings, you could install a driver with an application to have setting options. i think you could download that through OEM website of your soundcard. if you have Win 7, no reason to back to XP.
Correct; it would appear that team-rng simply was using the generic Sound drivers for their card, my Vista Desktop and Windows 7 laptop both posess equalizers (treble/bass) as well as setup for 5.1 surround.
if you have more than 3.2gb of RAM, you must use a 64-bit Win 7 to optimize system performance.
the limit sits around 3.5-4.0GB of RAM, it's an artificial limitation, but a limitation none-theless; the main reason for running a 64-bit system isn't necessarily RAM (although, obviously, if you have more then around 4GB you will have more RAM in x64) the main reason is if you have a 64-bit processor. And of course you could use Windows XP x64 (or 64-bit edition if you have an Itanium) or Vista x64 as well, but that's just being pedantic, since win7 is the only other OS the OP has suggested they have.
the only problem there is that not all software and/or drivers are compatible with 64-bit yet.
While this is certainly true, for the most part, only custom-written applications built for DOS systems will not run on a x64 PC; the only things one would need to worry about are things like old sound cards or network cards, and if somebody is willing to scrap x64 just so they can use their 8 dollar network card, well, that's kind of silly
Anyway, I think the main confusion vector was the term OSRI...
