System Freezes at random times GeForce GTX 745, nvidia-346.35 drivers Linux Mint

Installed Linux Mint on new (to me) desktop computer. Computer will freeze at random times ranging from 5 minutes after boot to as long as 3 hours after boot. Cannot Ctrl+Alt+Backspace, or Ctrl+Alt+F_ once it is frozen. Mouse and keyboard unresponsive. Cannot SSH into box from another machine.

Dell XPS 8700 with GeForce GTX 745 card. I have installed the nvidia-346 drivers.

I can attach the NVIDIA bug report, but it is after a reboot, as I cannot generate anything after the freeze. Also, I’m not sure how to attach a file on here yet, headed to figure that out now.

Let me know if there is anything else I can send from system logs etc.
