Dell Inspiron 14 motherboard replacement help

My Dell Inspiron 14 just bit the dust—motherboard is officially dead. Is it actually worth fixing? Honestly, the thing feels brand new since I barely use it. It’s running an i3 6006U, 4GB of RAM, and an SSD...

If there's a logical reason to repair it, where on earth am I supposed to hunt down a replacement motherboard?

On the other hand, if this is just throwing good money after bad, can I even get anything for it by selling it as-is?

Thanks

The processor and 4GB of RAM are usually soldered right onto the motherboard, so you don't really have much to work with here.
