Hello im new here, i would posted this under PC hardware, but there was no mouse section

. This seems the most adaquate place to post my question. Well here i go, when i press the wheel of my mouse it works. But if i try to scroll anywhere it wont scroll, it is very frustrating because ive grown adapted to the scrolling. The mouse does not have a brand came with computer, but it is a model SAGM002.
