You're facing some issues with your PC not displaying properly after a recent cable change. It sounds like the HDMI connection might be loose or damaged, and even after re-seating everything, the problem persists. Since the GPU was recently replaced, it's possible the issue lies with the motherboard or another component. I recommend checking the physical connections thoroughly and ensuring all cables are securely attached. If the problem continues, a professional repair might be necessary.
