Random game crashes

[MajorChipHazard]

Hey guys, so my problem is this:

 

I'll be playing a game, such as BF4, Diablo III, or World of Tanks, and then something weird will happen.

 

My screen will go black, and I will be booted back to my desktop, and then the "Asus" logo with the DVI sign pops up in my top left corner of the screen for a few seconds, and I won't be able to get back into my game.

The only way to get back to it is to sometimes alt tab depending on the game (BF4), while in other games, such as world of tanks, I have to physically sign out of my PC, sign back in, and relaunch the game.

 

Typically, it seems to happen alot on world of tanks, and having alt-tabbed and done other things and then tabbing back into the game seems to increase the chances of it happening.

I've only ever had it happen about twice on Diablo III, and it just happened for the second time prior to posting this.

 

I'm running windows 8.1, and I am running the latest drivers from AMD, I even switched to the beta drivers to see if that fixed it, and it hasn't.

 

Any ideas on what could be causing this?

Could be your overclocks, try turning them down a bit (GPU or CPU)

This was all happening prior to my overclocking as well.  I only recently overclocked my CPU & GPU.  I had my PC @ stock for over 2 months before I overclocked to make sure my hardware was stable before overclocking.
