It's not a matter of not being able to do photography, but people don't want to bother with learning the knowledge and putting in the work it takes to make good pictures. (However, you can take many good pictures with minimal effort, still requires a sound foundation in theory though.)
I looked and while your first shot is OK, I'm not impressed by your second shot. Particularly how you framed/cropped it so the heatsink takes up exactly half the frame and how the CPU butts right up against that dividing line. It throws the harmony out of whack.
If you're referring to the awful lighting and camera work in the video in the post preceding yours, then I agree, your work is much better. They would look great in motion, but as stills, they leave much to be desired. Do not assume just because you know how to manipulate light for stills that photography is "easy" for anyone.
