Windows 7: Co-Workers laptop BSOD 0x7B

Win7 Ult BSOD 0x7B CLASSPNP.SYS

Hello! My co-worker brought me her [personal] laptop because "it keeps crashing". When I received it I attempted to boot it up, and it went straight to the Startup Repair, I let that run, completely unsuccessful, as always, and it would not let me perform a System Restore to an earlier point. There was no System Image that could be reloaded, and when I ran the Windows Memory Test it completed with no errors. It will not boot into Safe Mode, it hangs on CLASSPNP.SYS. I found this thread when I attempted to run the sfc /scannow command I kept receiving the following:
Beginning system scan. This process will take some time.
There is a system repair pending which requires reboot to complete. Restart Windows and run sfc again.
Reading the BSOD-Posting Instructions the C:\Windows\Minidump directory is empty, and because I can't boot this thing I cannot run the SF Diagnostic Tool, I tried to run it from the recovery Console via command prompt, but no luck.

I have the disc, but cannot boot to repair the OS install, and cannot install because she upgraded to Windows 7 Ultimate from Vista and has no clue where the key is.

Windows 7 Ultimate x32
Toshiba Satellite L305-S5921

I'm a little stuck now, and help from the community would be awesome, this is about as far as my "expertise" goes, just don't tell my boss lol.

I have removed the hard drive and plugged it up to another machine via USB adapter bridge, Ran Symantec's & Malwarebytes, both clean, ran chkdsk, all is well, ran Western Digital Data LifeGuard Diagnostics and it passed all test. Still crashing as before.
