*HELP* File type associations for my hard drive (really angry)

This is making my [color=red]extremly angry.[/color]
[color=#ff0000][/color]
One day, my hard drive just randomly decided to not open when i double click and instead search it, i thought fine, so for a couple of weeks i decided to just right click it > Open. (this just happed about 2 weeks after reinstalling windows, and im not doing that again.)

But today i thought id change that… and i was wrong.

I opened up file type associations from the tools menu in my computer, and i found that “open” was missing, so i created open, i tryed this out and it worked, apart from it opened it in a new window, i went back and tried and and again and again. now i cant delete them:

I need help, ive searched in google, and all the file type associations are to do with “right click, open with, select power point, and chose allways open with”… this wont work with hard drives…
