Notebook Hardware and Upgrade Questions

Hello, not entirely sure if this is where I should post this but every time I start up my computer, the Disc usage goes from 0-100% within seconds, stays there for several minutes, and then begins to progressively drop while still spiking to 100. I play videogames (the requirements for which this laptop theoretically meets easily) and if I start anything more taxing than Google Chrome, the laptop will immedately restart as if the battery had been yanked out and replaced. I have only noticed this happen within the first 15 minutes of starting my computer, which is why I checked memory use.

I have a few screenshots here, which includes system info, and the Serial Number is [edited] with a Model Number of W2M88UA. 

I have attempted turning off some of the data collection apps that run automatically on Windows 10, and it seemed to help when I did it initially, but the problem has persisted since then, although it does seem to recover from the overuse with less time now. I have also run a Virus/Malware scan with both the Antivirus I use and Windows Defender and both came back clean.

I'm wondering if this could just be an issue with the age of the laptop (warranty did expire 7 months ago), or if there are other steps I could take to attempt to mitigate this. Any help or advice would be extremely appreciated.
