Gta V lenovo legion y520 fps drops and sound jam

[ROUGH N' GENTLE]

Hi! I've got Lenovo legion y520 with specs:
CPU: Intel Core i5-7300HQ 2.50 GHz/ 3.5 Ghz with boost
RAM: 8 GB DDR4 2400 MHz From samsung
GPU:NVIDIA GeForce GTX 1050Ti 4 GB

the problem is that there are drastic drops from 60 fps to 12 along with sound interruption, changing the settings to the lowest details does not help, someone has struggled with a similar problem and has a solution? thank you in advance! :)))
