BSOD during windows startup; can't safe mode; startup repair can't fix

[frolic]

Consistent BSOD during Windows startup for both normal mode and safe mode. BSOD problem started shortly after buggy installations of Microsoft Visual C++ 2005 x64, Microsoft .Net Framework 1.1, and AMD Catalyst Drivers 13.9; and turning off Microsoft .Net Framework 3.5.1.

Startup Repair is consistently unable to fix: 0x0000007e (0xffffffffc0000005, 0xfffff800033bf6d6, 0xfffff880009a7578, 0xfffff880009a6dd0).

I accessed the dump file of the BSOD-inflicted drive by usb-connecting it to the same pc, but that's now running a functioning, system hard-drive.

BlueScreenView shows these following files to be problematic:
atikmpag.sys
dxgkrnl.sys
dxgmms1.sys

The hash of the atikmpag.sys from the BSOD-inflicted drive is identical to the one in the functioning drive, so I don't think this is the root problem.
However, the hashes of the two dx files (dxgkrnl.sys, dxgmms1.sys) are different. I have replacement files for the broken dx files, but I don't have, nor know how to get, the access permission to replace them.

I'm at a loss for what I can try at this point. I used DM Log Collector and uploaded the resulting file. Any help is appreciated, thanks.

Henry,

The cause of the problem may be related to a Windows 7 installation which has never seen any updates.

Host Name:                 HENRY-PC
OS Name:                   Microsoft Windows 7 Home Premium 
OS Version:                6.1.7600 N/A Build [B][COLOR="Red"]7600[/COLOR][/B]

Can I just confirm, you have no way of booting into Windows at the moment. Correct?

Yeah, I have no way of booting into Windows with the corrupted drive.

But the problem isn't the OS version because I took the dump file from the corrupted drive and put it into a fresh install of Windows 7 on another drive; this was the only way I could produce a log with the DM Log Collector since it only checks one directory for dump files. Sorry I should've mentioned this but forgot to. I attached the original dump file in case that helps.

The corrupted drive has the most recent updates for Windows 7 Home Premium x64 (January 2015 updates).

Is there any way I can at least access the files on the corrupted drive to back them up?
