Hi, I recently purchased a GTX 780 and installed it, uninstalled my old drivers from my GTX 660 and installed the new ones for the 780 and everything, and now every time I go into a game, after about 5-10 minutes of game time my computer crashes. I get no BSoD, no warning, no anything... the screen goes black and the whole computer instantly turns off, then about 10 seconds later it turns itself back on. When I play a game like Skyrim with 100+ mods, it'll reach about 75-80C but when I play a less GPU hungry game like FIFA or WoW, it only reaches about 60-65C. I have no idea what is going on and I've looked all over the internet for answers to no avail. Anyone have any ideas?

Specs are:
Gigabyte Z77-HD3 Motherboard
AZZA Dynamo 850W PSU
2TB HDD
16GB RAM
Intel Core i7-3770k @3.50 GHz
EVGA Geforce GTX 780 3GB
