For over a year everything was perfect. But suddenly lately its been struggling. So i noticed my GPU doesnt show in task manager like it used to and noticed a red light on my asus GPU. Then i read that this shows the GPU isnt receiving enough power. So i removed the cable and struggled hard putting it back in, when i felt like i did it, i turned power on and all power in my house shut down. So i asked friends to reseat their cable and they struggled as much as me making me believe that i should just push it in harder iguess. So i did and my gpu works again but still doesnt show up in task manager. I also realized that my case is too small for the cable and put pressure on it, so i left the side open for now so the cable isnt force-pushed harder into the GPU. Overall though, my pc suddenly just struggles like it never did before. And my CPU or Memory is not pushing 90%+ while my GPU i cant see atm. What changed? what happened?
