large icons on my laptop screen

After closing out a video game, my icons suddenly got large. I restarted my comuter multiple times to no avail. I tried to resize my icons, but it still wasn't the same as it was before.

Simple Specs: Laptop - Acer Aspire A515-43 RAM - 4 GB 14 GB of available storage at the time suboptimal wifi connection

I do not know what else to do, so I came here. Any help is appreciated.
