I think you just loaded a bunch of bloatware. The only drivers needed for your system as stated above are the chipset driver for the motherboard, the sound card driver, the LAN driver (if you're using the built-in Ethernet LAN), and your graphic driver for the GTX 680s. I would uninstall as much as possible. Or beter yet, start over with a fresh install of Win7.
Fortunately, I haven't put any of it on my new system yet, but thank you both for your advice! The sound and LAN are actually working well without an external driver, but I'll definitely get that chipset one loaded. Thanks again!
