I just a couple months ago purchased a Dell G5. I have played loads of games such as Rust, Apex legends, Counter Strike, Fortnite and others but for some reason PUBG and Rainbow Six Siege will just completely Freeze my computer to were I have to hard restart. I have an I7 cpu and a RTX 2060 GPU 16GB duel channel ram. Sometimes i can play on siege for 5 hours without a freeze sometimes i can play for 5 minutes. I can play Rust on high settings for 12 hours straight doesnt matter.. never had a single crash. As i said this a pretty new laptop i purchased i believe the beginning of march this year so i have no idea what to do. I have read alot of stuff trying to figure it out and i have checked the history logs and the only error i see is from me hard restarting it.
