Please help me, what is this?

Just tried to put the motherboard, it didn't work out, took it off. Decided to examine just in case, saw it. What is it, and will it interfere the PC?

The top circle is a screw hole. That is how you affix the board to the case. The lower circled part is a solder joint . It is how parts are affixed to the motherboard.

Верхний круг - это отверстие для винта. Вот как вы прикрепите доску к чехлу. Нижняя обведенная часть представляет собой припойное соединение. Это то, как детали прикрепляются к материнской плате.

If I hurt it a little bit, is it bad?

It doesn't look like you damaged anything. The traces are more delicate than the mount points.
