Video output crashes & computer becomes unresponsive when mining RVN

Over the past month when i decide to mine ravencoin, after a few minutes of mining my video output inevitably crashes and i cant do anything but to force shutdown my computer and restart.

I have tried mining on several mining softwares like nanominer,Kawpow miner, Teamredminer, NBMiner but they all result in the same crashes.

Im not sure whats causing it, if anyone has any idea please enlighten me with your wisdom 😀
