Right mouse click don't make click sound , but works well (1life gm:assault)

Your vids are set to private so I was unable to view them but it's really not necessary. Your mouse button's tactile feedback is gone (sort of obvious). If handy with a soldering iron, you can replace the switch, higher quality mice use switches like these http://www.amazon.com/OMRON-Micro-Switch-Microswitch-D2FC-F-7N/dp/B005NYGK16 while cheaper mice use cheaper momentary switches like this http://www.digikey.com/product-detail/en/B3F-1000/SW400-ND/33150 (those mice usually aren't worth repairing) - you'd need to open your mouse to see which yours has.
Note that if the mouse is under warranty, you may be able to RMA it for that since tactile feedback is an expected feature from a mouse button
