So this thought came to my mind as I just had my cousin take apart and re assemble my PC . And I am afraid that he didn't insert my graphics card securely. And I am kinda scared to open up my PC and tinkle around as I have never done this before. So just a question I know it sounds dumb but: will there be any symptoms or occurring signs if your graphics card wasn't mounted securely in it's slot when building your PC and then you turned on your computer later. Will it still run smoothly as if nothing happened or will there be any visible problems with the display or gameplay while computer is running ? Would appreciate any comments if anyone has the time
