Can't find a motherboard for my i5-3550

[EndureCoreNas]

Hey guys so I currently have a Gigabyte Z77X-UD3H with my i5-3550, but some of the usb ports aren't working so planning to replace the motherboard and swap out some things like my GPU etc, but it looks like all the compatible ones are now discontinued? I can't seem to find one anywhere.

Could someone suggest me one to purchase? Or do I have to buy a new CPU? I was thinking about the i5-6500, but it doesn't seem to be a large enough upgrade to warrant a new CPU.

Thank you.
