Strange Crash with Certain EA Titles

Hello all! Recently I have been experiencing a very annoying crash after playing either TitanFall or Star Wars: The Old Republic. I will be in-game for about 30-90 minutes and all of the sudden the game will freeze (what I mean by freeze is exactly that; the image is frozen and there is no audio whatsoever) and I am unable to alt+tab or ctrl+alt+del to get out of it, the only solution that I have found is that I must do a physical reset by pressing the power button. This crash has ONLY occurred with these two games, and has not yet occurred with any other. I am able to play games like Battlefield 4 and Grand Theft Auto IV for extensive periods of time without experiencing this issue. After playing these games for 2-3 hours my avg. CPU temperature is around 70 degrees Celsius and my GPU is also around 70 degrees Celsius. My system specs go as follows:
--------------------------------------------------------------------
AMD FX-9590 8-Core Processor @ 4.7 gHZ
AMD R9-280X HIS IceQ X^2 w/ 3gb ddr5 vram
16 gb GSkill Ripjaw X series Ram (4x4)
ASUS M5A99FX PRO R2.0 Motherboard
KUHLER H2O 1250 Liquid Cooling
2TB Seagate Hybrid SSHD
750 Watt Corsair CX Series Modular Power Supply CX750M
--------------------------------------------------------------------
I do not get any precursor to the crash, no fps drops or lag of any sort. I checked my computers stability history and the only events that it showed was a "Computer Shut off Incorrectly" on all occasions that this has occurred. I clicked view tech details and it showed nothing other than "Your computer was turned off incorrectly". This is strange to me and seems like my computer was telling me that everything was still running correctly at the time but I just keep shutting it off physically even though I am unable to do anything whatsoever to exit the game when this occurred. Any ideas? Any help is greatly appreciated! Thanks!
