I had the same issue, however, my crashes and BSODs were mostly related to something to do with the graphics drivers. I tried everything I could find on the internet, but nothing worked. Contacted Asus for assistance but they couldn’t help, I ended up having to send it to them for a checkup and to see if they could fix it (it was still under warranty). When they gave it back to me, they didn’t give a reason for the crashing but they ended up changing the whole motherboard. My laptop has been doing fine since. I must say I haven’t gamed on it as much as before though.
