i just bought a brand new acer nitro v16 2 days ago and i opened it for the first time at my home yesterday after receiving it from my aunt, i opened youtube to listen to some music. at first it was going good and after a while the display froze and there was repetitive sound occuring all of a sudden while the video was playing. i tried to shut it down by clicking the power button but it didnt shut down. i tried using different keys but still it was lagging. after 10 minutes of lagging and repetitive noise, i tried long pressing the power button then it shut down [after a lot of tries]. then i instantly left it to charge fully and after a while i tried to open it again. this time i was using some app of this pc and the lagging happened again, but this time without the repetitive sound. and then i tried to turn the power down again, and this time also, no key worked. then same as before, after a lot of tries of long pressing, it stopped and the laptop shut down. then i left it to fully charge and put it in my bag. then i opened the laptop again today, the same things happened. 2 times. please help me. i need to use this laptop for a long time.
