how do i know what pci slot i have

do ur school work , if u have more sticks , each core gets assigned to a ram stick, and i dont know what im talking about?

Noob quesiton, I know. But, i can't figure out how to remove the PCI expansion slot covers. I take off the clip, but they're in there pretty good. I tried just pulling towards me, like how it usually works, but I can't figure it out. If you have no idea what i'm talking about, I can provide...

I use an hp 15s eq 2xx pc, and i want to know how many SSD slots i have. And on another note, i know i have 2 RAM slots, i want to know what is the max RAM that each slot supports.
