Hi there,

So the other day I booted my computer up like normal and it got halfway through the four windows lights coming together to create the windows logo (after bios boot and just before user login screen) when it flashed with a quick blue screen then rebooted on its own accord. There's no way I can get past this point in the system boot that I've been able to figure out and I was hoping that someone here could help me.

I turned off automatic restart on system failure and it said something about the file cng.sys, so I am thinking that file has become corrupted somehow. Or am I way off. I don't recall installing anything new hardware or software-wise recently and I'm unsure how this happened.

Things I have tried:
Automatic startup repair
Removing CMOS battery and reinserting
Removing individual RAM sticks and trying each of the two separately
Unplugging everything from the back except the mouse and keyboard
Boot to safe mode
Flashing a BIOS Update
Inserting Windows 7 CD and doing a system restore and the other repair options on there
SFC scan with the Windows CD

I assembled the computer myself in 2010 sometime and it has
Gigabyte h67ma-ud2h-b3 motherboard
2x2GB RAM
GTX 560
Intel i5 2500
Corsair PSU - 500 watt I think?
card reader
optical drive

It seems I'm able to access the command prompt. Is there a way I can replace the cng.sys file with a good one or is that not something that would work? I am trying to avoid reinstalling windows as there is data that I would like to keep on the drive.

Any help is appreciated.
Thanks.
