Alright, time to break out the pictures I guess.
This is a motherboard. Or it should be, idk if that image linked correctly. Everything in a pc connects to this, and so you’ll find everything you need to mess with here.
In the upper right of the motherboard, towards the top of your pc tower, you’ll find the ram sticks. There should be several slots filled with little flat pieces of metal and plastic. Remove these by unlocking the little plastic clips at their base and pulling them up and out.
The cables connecting your hard drive to your motherboard should be located just below these. They will be flat cables leading up to the upper right of your tower. there is a plastic clip holding it in place, simply holding this in the same way you would hold a clip on your average child lock should enable you to take it out.
The graphics card should be located in the bottom left of your motherboard. If it’s a large one then it will likely be held in place by a screw. You will require a screwdriver to take it out, in all likelihood. There will be a plastic clip like the ones that held in your ram on the side opposite the cables that run out of your pc.
It should be obvious, but make sure to unplug everything before doing any of this. You don’t want to get electrocuted and a number of cables will get in your way. Also make sure to be gentle, but firm. Twisting or forcing parts will only break things further, but being gentle yet firm will get you where you need to be.
