Game constantly crashing after patch 2.1

[Diablos_Deathbringer]

I have gone from never crashing before the patch, to crashing all the time. I can get in to the game and play, but at random intervals it will crash for no apparent reason.
The crash happens in 3 different ways:
1. Game just freezes, and it makes windows freeze along with it, requiring a reboot
2. BSOD
3. The game just crashes into windows, and i do not need to reboot.

I have the latest drivers installed for all my computer parts
I have tried rebooting the PC
I have checked the temperatures, and this is no overheating problem
I ran the RAM(16GB) test in Windows 8.1, and it found no issues
I tried lowering the graphics settings, even though i have been running on max without issue. It did not help.
I tried reinstalling the game. Still no luck.
I made a clean reinstall of the latest nvidia drivers available from the ASUS website, but that did not work either.

Windows 8.1 Enterprise
Asus Geforce 670
Gigabyte Sniper M5 motherboard
16GB RAM

UPDATE: I resolved my own issue. Even though memtest found nothing wrong with my RAM, i tried removing 2 of the 4x4GB modules, and it solved my issue
