Are you overclocking? As you are getting BSODs, you should stop overclocking and run all the hardware components like CPU, GPU and RAM to their default settings.

Test your RAM modules for possible errors.
How to Test and Diagnose RAM Issues with Memtest86+
Run memtest for at least 8 passes, preferably overnight.
If it start showing errors/red lines, stop testing. A single error is enough to determine that something is going bad there.

Stress test the Graphics Card using Furmark.

Stress test the CPU.

Plus, as it is a GTX 760, it is supposed to have some driver issue. And unfortunately I dont know any driver version that works good with GTX 700 series. You may try the drivers on a trial and error basis:

• 320.49 WHQL
• 327.23 WHQL
• 331.58 WHWL
• 331.65 WHQL
• 331.82 WHQL
• 332.21 WHQL
• Any other version later

Get them from Drivers - Download NVIDIA Drivers

Do a clean install on all of them. Uninstall the previously installed driver first.
Uninstall All nvidia items in Control Panel > Programs and features

• 
  
  • 3D Vision Control Driver
  • 3D Vision Driver
  • Graphics Driver
  • HD Audio Driver
  • PhysX
  • nvidia Update
  • GeForce Experience
  
  (Are you using nvidia chipset drivers? If so, dont uninstall anything other than those are listed).
• Now follow Drivers - Clean Left over Files after Uninstalling
• Download the target WHQL. While installing, Select Custom (Advanced) install. In the next page, follow this settings:
  
  

Lengthy process, but the only stable version of nvidia is 314.22 lately, which does not support 700 series GPU.
