Hey all, I will explain my scenario as best as possible. Was watching a TV show and when I went to switch from HDMI 1 (TV) to HDMI 2 (PC) the monitor displayed No Signal and then a BSOD occurred. After the BSOD windows updated itself and I proceeded to get back on ARMA 3. About 20 minutes into playing my whole computer seemed to crash. Screen went white for a split second and then black, then my computer restarted itself and then shut down completely. I turned it back on and since then everything has seemed fine.

This is my newest build that I did about a week ago so I have been keeping an eye to make sure all hardware is working correctly. All of my temperatures are excellent (CPU, GPU, RAM, NB and SB). Same goes for voltages. Really stumped as to why these random events occurred. I've been back on it now for a few hours and everything seems fine. If anyone has any suggestions as to what the culprit may have been please let me know. Heres the specs:

Asus m5a99fx pro r2.0 with latest BIOS
FX 8350 stock clocks, seems to run about 100-110 F while gaming
Radeon R9 270x - video playing through HDMI
16gb DDR3 1600, timing on Newegg shows 9-9-9 when BIOS is showing it at 11-11-11
Corsair HX750w
Windows 8.1

Will also add that I am using Catalyst 14.2 beta drivers. Just had this happen again while playing ARMA 3, screen flashed and said "No Signal", my computer seemed to restart itself and when the screen came back on it was shutting down windows, and then it shut off completely.
