Does anyone know where I can get 32-bit drivers for XPS 14z? I have:

Management Engine Interface Driver
Mobile Intel Series 6 Chipset Driver
Realtek RTS5209 Card Reader Driver
Texas Instruments TUSB 7320 Driver
Intel Centrino Advanced-N 6230 Driver
Atheros AR8151 Driver
nVidia N12P-GV-S Driver (downloaded from nVidia it won't install)
Intel HD Graphics Driver (got from Windows Update)

What else do I need? List is here for reference. I can't turn off the audio even though the speaker icon on my taskbar shows it is muted. Which driver is for the keyboard function keys? The four directional keys don't work.





What to do with the extra RAM (have 8 GB) other than using it for RAMdisk?
