(Fixed!) Sudden No Signal on monitor, suspect GPU

I can play Skyrim easily, no problems. It's not highest, but it's enough for me. I can also play Tribes: Ascend on highest, no problem. However, I just recently discovered a new (old) title: Dragon Nest, hosted by Nexon. This is a low end game, sort of anime looking, but for some reason my screen will, after ~20 minutes, go black and say "No Signal" as if it were disconnected. The tower is still operating, and I can hear the BGM from the game, but there's no display. I have checked the cords, updated my drivers, cleaned out my drivers (an experience I will never again attempt...it took me forever to get my GPU driver working again), and am able to play the game on lowest settings without any foreseeable issue. However, when I try to set the game on highest setting, the GPU usage goes from ~20% to 99% and begins to overheat. I had this happen on City of Heroes once, maybe twice, but updating my drivers fixed it. It wouldn't surprise me if the game had a bug in it (an option I am still open to) but I am worried that my video card is starting to give out. Alternatively, I've been told it could be my motherboard. I have noticed this though: My shader and core clock is always at 100%, even when surfing the web. I'm not even sure if there's a problem (the game could be messed up) or not, but I'm asking here just to be safe.

Solution
This issue has been resolved (will post what I did for future google searchers)

After updating to the latest drivers a second time, I installed the EVGA precision tool and adjusted the fan speed to temperature settings. By bringing the speed limits of the adjustments down by 10c each (it's a chart with 5-7 dots on it, just bring them left from one line to the next) I was able to keep the card running at a safe 70c with no issues. This has even helped my other titles. While Dragon Nest still has poor optimization, leading to these issues, I consider this a sufficient workaround as it has stood for two days. If anyone would like to post another tool that does the same thing, but without the overclocking stuff, feel free.
