Whenever I start up Fallout 4, my PC crashes, and the monitor freezes, but the only way to turn off the computer is through force shutdown.

Specs:

Processor: Intel® Core™ i7-4720HQ CPU @ 2.60GHz (overclocks to 3.4)

System Type: 64-bit Operating System, x64-based processor

Graphics Card: GeForce GTX 860M

RAM: 8.00 GB

Hard Drive: 914 GB (704 GB free space)

Any help is greatly appreciated, I've really been looking forward to Fallout 4
