How do I get higher FPS on Windows 10

[Tiery00]

I'm trying to figure out how to improve my FPS in my video games. Currently, I usually have lower than 20 FPS o top of that my FPS keeps jumping from 1 to 5 to 20 (it's all over the place). I can't run GTA 5 Online or Dead by Daylight with my PC because it always lags. Even with the lowest settings it still lags. I frequently update my desktop but it still lags. I updated my BIOS and Driver- Graphics yet it does nothing

I have a Windows 10 All-in-one, product name 23-q214, and number T4A02AA#ABA

Basically, you can't -- as the PC has integrated graphics and no way to add a graphics card to it.  It's not a gaming PC.
