Licensed game, bought it with my own cash legitimately and everything. <3 DA too much not to legitimately buy it :P. And heres a screencap of speedfan normally:
and here's a screencap with the game running:
The only time I've looked into overclocking was on my graphics card, and I just let the ATI thing set it up for me. I thought it would help me play RIFT but my computer was unsupported anyway, it had the same problem I'm having right now. But other than that I've never touched anything having to do with overclocking.
It does not die in fullscreen, I can play for hours and everything's dandy.
Although I was guessing it was overheating and it probably is. I don't really know how to solve that besides playing in fullscreen/buying new stuff for my computer which I can't do right now.
