Well, I followed the above instructions, and loaded the Driver
The Good News: It seems to have identified usbfilter.sys as the problem driver.
The Bad News: I can no longer boot into windows.
Basically, when I restart windows now, I have two options: Startup Repair (which I'll get to in a sec.), and Start Windows Normally, which will immediately throw a BSOD, usually identifying usbfilter.sys as the problem (it once didn't name any particular culprit.)
If I do startup repair, when I get to the screen where I need to choose an operating system, there are no OSes available to select. I'm not sure why this would be, as I'm not using RAID on the drive where windows is installed. (Full disclosure - I have a total of 4 drives in my box: 1 on which Windows 7 is installed, one on which Fedora 16 is installed, and 2 which I have setup as a RAID 1-mirrored data drive, using my motherboard's controller.)
Due to the fact that it can't find my OS, none of the normal startup options seems to work, other than the memory diagnostic (which I doubt is the problem, since I replaced all my memory - see my first post), and the command prompt... which is useless, since all I can access is the X: drive, which I assume is a ram drive holding the system recovery program.
Any help would be appreciated!
