What do I do with my Dell computer? (Details Inside)

Three years ago I bought a core I5 computer from dell.canada, and it crashed every so often. On December it crashed while updating, and it cost ~$250 for a new hard drive.

I only need it for classes in the distant future.

I use my cell phone for everything now.

I have not used my computer after the hard drive was replaced.

Do I sell it? Keep it for later classes? Or toss in the trash? The computer is an all in one that doesn’t have a tower. I paid $1,500 for it.
