Unexpected shutdowns.... please help

[Moonunit707]

Twice now while playing Borderlands: The Pre Sequel my computer has unexpectedly shut down on my during game play. The first instance I first thought that maybe my GPU overheated and shut my system down. During my next gaming session I had an on-screen display of my GPU temps, which only reach 80°C a couple times and usually hovers around 77°C. EVGA precision X is set that when it reaches 90°C an alarm goes off. I never got an alarm and still the system shut down (Not fully, the power on LED was still lit). I went through the Event Viewer to find out some info and I don't know what it means. I will post a screen shot of the event details.

 

If anyone has some clue as to why this could be happening or any ideas on what else to check please let me know. If more info is needed, also let me know. I keep losing hours of save data and its frustrating. Thanks in advance

Try stress testing with furmark and see what happens.

So I ran the Furmark furry donut stress test using MSI Kombuster. I ran the test until my GPU temps hit 91°C and I ended the test. I don't really know what i'm doing, but I didn't have any issues.

Try lowering the clocks of the CPU on the BIOS, maybe it will work... By the way the sistem is Over clocked?

My CPU is overclocked to 4.2GHz and my GPU is factory overclocked from EVGA. It's a 660 ti FTW edition.
