I did this for about two weeks. It worked. Spent over 30 bucks on cables. The double bass improved the sound quite a bit. However, it was still just bad on top of bad, which didn't even make it OK. Did some craigslisting and got a DVD era 100w receiver, some BS22 bookshelves and a 12 inch sub for cheap. I bought some SM45s too. All in 300 bucks. Totally destroys the Logitech z906. A craigslist receiver and used speakers are the way to go.
you have to start by downloading ryzen, probably a good idea to download some ram too https://www.downloadmoreram.com/download.html (Old stuff could probably use it, but relies on manufacturers to care enough to put the fixes out)
