Problems with video drivers on a Aspire V15 Nitro

Hi there, i bought a Aspire VN7-591G-787J and im having a weird problem with my video driver (or the video Card Itself, i can't be sure of wich). I reseted to Factory settings and it works fine (im running FurMark for a couple of Hours as a video test), But when i restart the computer and run FurMark again the laptop freezes after a couple of minutes. I then restart, and geforce experience ask me to update again my video drivers (wich i did just after factory reset). After i reinstall my video drivers i run FurMark again and computer keeps stable for hours, but then again after a restart it gets back to crashing after a couple of minutes in any game ou FurMark itself.
