Turn my phone off through a computer

I have an Oppo F3. My sensor was bugged, and any calls made via Messenger, Viber, or WhatsApp would mean my mobile's device turning black. I need to turn my mobile device off through my PC and currently, I can't access my mobile phone. The power button and my volume button work, and even when it was working, pressing my "Power Off" button would just display a "Swipe to power off" function. Long pressing the power button would not result in anything specific, as it does in so many other devices. Virtually, there was no way I could restart my phone because as it seems, there just isn't a restart function in my phone. I've tried many stuffs, but will I be able to power off my device? If I could restart my device, or even just turn it off, the problem wouldn't persist.
