Recurring Boot Failure
For a month or two I've been plagued by an issue that leaves my computer unbootable. I've reinstalled Windows several times during this time and always eventually run into the same problem.
The typical sequence of events has been: Reinstall Windows. Update Windows. Install Drivers. Reinstall all applications. Move user data from old installation. Use the computer without issues for a few days without installing any new drivers or software. Try to boot computer one morning and go straight into Startup Repair which fails, forcing a System Restore. In the following days the problem returns, and eventually System Restore fails and I'm forced to reinstall Windows.
An observation throughout all of this is that reboots from a working Windows never have failed. All the failed boots have occurred immediately after the system has been powered down for several hours.
Before the most recent Windows reinstall, I tried to perform the bootrec commands. /fixmbr and /fixboot worked. However, /Rebuildbcd failed as it couldn't identify any Windows installations. This was done from the command prompt in the WindowsRE on the Windows 7 installation dvd which did recognize the Windows installation upon launching.
The Startup Repair log from my most recent un-System Restorable boot failure:

Things I've tried:

I've attached my results from the SF Diagnostic Tool as per the posting instructions of the BSOD subforum, in-case it would be helpful to anyone willing to try to help me with this. I'm all out of ideas myself. Any help would be greatly appreciated.
Extra. Don't know if relevant or interesting.
Background:
I built my computer myself, and it's been running fine for about three years. About one year ago I added an SSD which I from then on ran Windows from. A month or two ago I decided to get rid of the defunct Windows installation on the old hard drive. I formatted the partition, and this is where all the problems began. First I had messages about a missing bootmgr which I took care of by reinstalling Windows on the SSD.
A week or two ago I thought I'd found the solution when I realized the old Windows partition (now D:\) still held the Active flag, which was a bad thing. I removed the flag, and have since reinstalled Windows on C:\, but the problems persist.
Freak happenings:
One three separate occasions I've had symptoms which haven't since returned.
I once booted into Windows to a Device Manager filled with several malfunctioning "WAN miniport" entries. Internet connection wasn't working. I ended up performing a System Restore.
Another time I came into Windows and the keyboard and mouse weren't working. I tried different USB ports to no avail. On a reboot, I ended up in Startup Repair and had to perform a System Restore.
Finally on one occasion during boot the "Welcome" screen that usually only stays for a couple of seconds remained for a couple of minutes. Once in Windows, many things loaded incredibly slowly, such as System Restore, which I eventually ran.
