Random restart after some usage during the day | Legion Series | Page 1

Model: lenovo legion pro 5 16ARX8 (gen 8) with ryzen 7 7745hx, rtx 4060, 16gb ram ddr5
Issue: after using the laptop for a while during the day, the audio in my headphones (connected via 3.5 jack) starts to sound like it's cracking, this soon followed by my whole laptop powering off and booting up again. It happens most of the times while playing more demanding games, but I also had it once happen while just using firefox (browser). After it restarts, it will keep restarting unless I let it rest for a bit powered off.
What have you tried already?: unplugging the power cable seemed to have worked the first time I had this issue but last time it also happened when using the laptop on battery. I also tried to lift the laptop so the airflow doesn't get stuck in my desk, it did not seem to do much.
When did it start producing the issue: like 3 or 4 days ago. For reference, I got the laptop on the 12th, a week ago.
Did you install new drivers or software?: nvidia drivers (536. 99 DCH) from the nvidia site, idk if important but I use the laptop with the dedicated gpu only, the way I think is the default way, and lenovo legion toolkit
