This is so sad, i just bought a gt72vr 7re, and i have the same problem, i have tried so many things like, updating drivers, rolling back drivers, updating bios- vram, power options, no AA, no V-Sync, no triple buffering, reinstalling windows, utilities and drivers from official website, GSync off-on, Refresh fixed, resolutions, all settings on low, set it on 60hz, clean drivers installation.... i dont know, write it down and i probably did it already... just in case, i have tried all my games and same thing happens, i reinstall- updated direct x. I was so happy about my new laptop, but keeps crashing with only 10 minutes in game! for the price i paid? plz. I hope you find a solution brother and if u find it plz let me know! :/
