Hello Digmoons and welcome to Sevenforums.

I'm getting a little bit suspicious looking at your Hardware configuration. I've been looking around Microsoft's recommendations on installing Windows 7 on systems as yours. Your .nfo that you provided, informs that the BIOS is from 2007, which we'd usually say is old, and should be updated.
However, it seems like on ASUS' website, there's no such thing as upgrading a BIOS, which works properly with Windows 7. It's certainly not one of my best quotes, but I'd maybe consider to downgrade your system, do things like Windows XP. Tough, it'd recommend you do run the Windows 7 Upgrade Advisor tool.

Microsoft Upgrade Advisor

The Advisor is a great too to track down hardware, devices and even drivers that are compatible with Windows 7, or not. If you want to check out this manually, go to their website, where you can type in your own Hardware, and check if it works with Windows 7 or not.

Windows 7 Compatibility Center

There's a few things to consider here.

BSOD Analyse

Update this driver

There's a newer version of this available.

It'd honestly consider to downgrade to another OS. Windows 7 is in my opinion too required on your system, most of your drivers are very old and shouldn't be used within Windows 7. Your dump contains more blamed drivers than I can count. Run the Advisor first.

Best Regards,
Frederik.
