Hi! I recently bought an Asus GTX 760 this February and after awhile of smooth gaming I left the game idle and when I came back the game slowed down; delaying the sounds and movement then when I moved the mouse the game went normal again, I turned off my computer and checked the GPU and smelled somewhat of burnt metal inside. My case has no cooler whats so ever only 2 built in fans (Antec 100). I was wondering if can it be repaired/fixed or ill just void its warranty? Thanks for the answer! Advise rather.
