My Motherboard Has Become Flexible.I Mean I Can Bent The Board A Little Bit Sideways.What Does That Mean?

i know its a little bit funny question but my 3 years old intel motherboard has become flexible i mean i can squeeze/bent the board (not completely) a little bit.does it mean the board is dying or has a shorter lifespan left or is it just like that?i have tried another board of the same model but it could not be squeezed,its a refurbished board from intel i think.will i get a warranty replacement from intel since the board i am having is still under warranty or will i go with my old motherboard which is working flawlessly with some very minor issues.does intel send new board in warranty replacement or they send refurbished board?if they send refurbished/repaired board,then i dont need it.
