Originally I thought my issue was game or even driver specific, but I ran into it again on a different game today, so I figured I should ask on here. So here goes.
My issue is that my computer will randomly freeze sometimes while playing games, and its usually in locations that aren't really graphics intensive. The three places it's happened so far are World of Warcraft (multiple times, several of those in the same area), Arma 3 (only once), and now Tom Clancy's The Division Open Beta (twice in the same area). I originally thought it was just an issue with World of Warcraft, but then it happened on Arma 3, and after a while it stopped happening altogether. Just today I tried the Division Open Beta and it happened again.
I can still hear sound just fine, which in and of itself isnt that strange: a sound file could be really long and just continue to play while the computer is frozen, but I can still hear people talking over VOIP too, however, unlike other similar issues that I've read about, I cannot interact with the program at all. Clicking, pushing buttons, etc do not produce any new sounds, and the people on VOIP cannot hear me talking to them.
I cannot alt-tab, ctrl+alt+del, or really do anything. I have to hard reboot.
What drives me insane is that no errors show up in Event Viewer or even in WhoCrashed, so I have no idea what is causing it. I have an Antec 1200W PSU, so I dont think it's a lack of power.
I've read around and didnt see anything that helped, and the few threads I saw that were similar didn't sound like my issue.
Here's what Ive tried:
-Updating graphics drivers, clean installation
-Checking Event Viewer (nothing shows up, there were event logs for Nvlddmkm crashes, but the critical crashes produce no events except loss of power to the kernel when I hard reset)
-Turning off power save in the Ethernet adapter options
-Benchmarking drives via Defraggler (both turned up "GOOD")
-Ran mdsched with 2 passes (returned no issues)
-Rolling back graphics drivers
Im running a GTX 770 with 16GB RAM on an i7 4930k, 64 bit Windows 7. I think the CPU has been factory overclocked from 3.4GHz to 4.0GHz, since I get an error message saying "overclocking failed" whenever I hard reboot my computer.
Ive read people suggesting a mobo issue, but really I'd like to see if there's anything else it could be, since Im not really in a position to replace my mobo right now.
I can post dxdiag and msinfo reports if needed.
Thanks for your help.
