Hello, recently my computer has been shutting off at unexpected times while gaming. Certain games like League of Legends and Plague inc, etc. won't shut my computer down when I have V-Sync on but others like Mad Max, Left 4 Dead 2, Subnautica, Middle Earth, etc. shut off my computer even with V-Sync on. When this problem occurs the computer turns off, but after about 40 seconds it turns back on by itself. During those 40 seconds the power and restart button are unresponsive. My graphics cards, EVGA GTX 770 2GB, highest temp before shutdown is 80c and my Cpu, Intel Core i5 4690k, highest temp before shutdown is 55c. My other specs are:

PSU: Antec HCG 750m
Motherboard: Asus Z97 AR
RAM: 8gb Ripjaw G.Skills

Any post is appreciated, Thank you!

I can confirm that updating BIOS lead to more GPU Voltage, but surprisingly also less heat. Mad Max ran at about 5-10, sometimes 15-20 degrees cooler. After 20 minutes of playing my computer hasn't shut off so that's a good sign. Will extensively test tomorrow.
