Most bsod's are either memory or gpu related.
The ram is easiest to tackle first.
Set your ram voltage to vendors spec for stability.
1.65v will NOT damage the dimms or your cpu.
Try 1.64v first if you still have issues you may have a bad module.
Download and install Memtest86+. http://www.memtest.org/
Run bootable iso image,checking one stick at a time.
If you find no errors, dump your gpu drivers
And install the newest version from Nvidia.
