Hi and welcome to the forum:
Is your card a full-size card or micro-SD with adapter?
What size and brand/model is it please?

Have you formatted it in the camera lately?

I suggest you try a new full size card.

I would also like to add what size card are you using. For some reason entry level cameras such as yours don't play nicely with SDXC (64GB) or larger SD Cards. Stick with 32GB (SDHC) or smaller SD Cards. Also avoid using Micro SD Cards in an adapter this causes problems as my colleague Trevor pointed out. If Canon designed the camera use it. It would take them directly without an adapter.

Stick with 32GB or smaller SD Cards and the problems will go away.

Your problem is the card size is too big for your camera use a Full Size class 10 32GB SD Cards. No Micro SD Cards in an adapter. These cause all sorts of problems.
