Elderscrolls, mgs, and fallout not appearing on steam store, help?

Like the tittle says, morrowwind, oblivion, mgs, and fallout (og) are not appearing on the steam store. They appear when i ask google if their on the store, but then steam wont send me a verification code to play it. I just got my first pc, so this is a little stressfull. Just got one becuase every time I bought an original 360 to play the original new vegas with out the updates that come automaticly, or that the xbox 1 will force you to update it if your connected before playing. Same with dark souls. Anyways everytime I got too the first bell in dark souls, the consol would break and stop working. Finaly gave up and went back to my xbox 1, but then that broke after the first bell too. Any tips to get the pc working? Thanks
