Hi I'm replacing my graphics card. I've remove the small cross head screws but have a screw as in the attached image. It is like a corkscrew. Where can I find a screwdriver to replace this?
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^You have to do nothing with that screws. Those screws fix the bracket to the GPU. If you want to remove the GPU you remove the bracket too. That's how it goes.
The bracket is mounted to the case with one or 2 screws. And you have to unhook the PCI-e bracket clip.
