Unknown devices listed in Device Manager - cannot find drivers!

Hello - Just finished my Windows 7 ultimate 32 bit HTPC build and install with following components:

1) ASUS P5N32-SLI SE Deluxe LGA 775 NVIDIA nForce4 SLI x 16 ATX Intel Motherboard
2) Intel Core 2 Duo E6600 Conroe 2.4GHz LGA 775 65W Dual-Core Processor Model BX80557E6600
3) CORSAIR XMS2 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model TWIN2X2048-6400C4
4) MSI NX7900GTX-T2D512E GeForce 7900GTX 512MB 256-bit GDDR3 PCI Express x16 SLI Supported Video Card
5) Turtlebeach Montego DDL Sound card
6) 2 Seagate Barracuda ES ST3500630NS 500GB 7200 RPM SATA 3.0Gb/s 3.5" Hard Drives
7) 1 Western Digital Raptor WD740ADFD 74GB 10000 RPM SATA 1.5Gb/s 3.5" Internal Hard Drive

I have 4 unknown devices listed. I am guessing these are all motherboard related drivers and based on what I can find online, they are

- Mass USB storage - USB 2.0 Controller
- Realtek Audio controller
- Silicon Image SATA driver
- NVIDIA chipset drivers

I tried that driver max dealie but I cannot get anything to download and install with the free version...

Anyone know where I can find these or is there some other version I can use? Thanks!

I could be off base here but...

If you have a Turtle Beach sound card installed, do you need the onboard sound (Realtek) to work too? If not, you need to disable it in bios and then you will not need the driver.

If you are not running a RAID setup on your Silicon Image chip, you won't need a driver for it either. Check the bios and see if you have it set to RAID or IDE. If you switch it to IDE it should solve your driver issue there.

After addressing that, on the other two, try uninstalling them in Device Manager and restarting your computer. Hopefully Win 7 will find them and install them correctly.
