I'm having trouble removing my old graphics card from my pre built pc, the m15bc by asus. The screws for the graphics card holding it in place are located outside of the pc on this metal "flap", My motherboard is a few millimeters away from the backside of the case, making it stressful to navigate. I push the blue lever down on my pcie slot to release the card, i push it down so its parallel with my case but im not sure if im pushing it down far enough, but thats as far as it goes without ridiculous pressure. The graphics card wont seem to budge with what i think is more than enough pull force, so i dont go too hard because i don't want to break something. On another note, trying to remove my power connector is just as hard. It wont even budge when i try to pull the thing out. It also has this plastic prong on the to which im not sure if thats causing issues, but i squeeze a little on it because it seems like a clothespin kind of thing and try to pull again, still no luck. It's hard for me to say where the resistance is coming from in removing my graphics card especially, whether its a hidden screw or i didnt push the pcie slot down enough. HELP PLEASE ON ALL OF THIS
