After Windows updates today, I restarted my desktop (for the first time in a couple weeks), and on boot up ran into a BSOD:

STOP: 0x0000007E (0xFFFFFFFFC0000005, 0xFFFFF8000355AB5A, 0xFFFFF880031CB3A8, 0xFFFFF880031CAC10)

I tried system restore, but there was only 1 restore point which was from all the way back in January. I tried it anyway but after 10 minutes of running it said system restore could not be completed.

Additional info:

I checked my BIOS and it is detecting my rams. CPU is Intel Sandy Bridge i5-2500k overclocked to 4.3GHz. I reclocked it back to stock speeds (3.3 GHz) in case it was causing the issue (I highly doubt that it is). But the problem persists.

Running Windows 7.
12 GB of RAM at 1333 MHz
OS on 64gb SSD.

What is causing this? How should I fix it?

Also, if it is caused by windows update, is there a way to undo the update with command prompt?

I tried safemode, and the blue screen comes up as well, but I am able to access command prompt.
