Since I started playing CSGO I have this habit when Im like too concentrated while playing a match, I get scared sometimes when an enemy jumps me by surprise or catches me off guard when Im not ready or just headshotting me from the side/behind, and the game has this loud "dink" sound when someone shoots u in the head if any of you are familiar with the game, so when it happens I kinda bash my mouse against my table a bit.. and after every bash I get nervous its gonna ruin my EC2-A eventually.. Im so self conscious about it that I check the mouse movement recorder (included in MarkC win7 mousefix) to see if the movement of the mouse is like usual and I didn't damage it...
the bash happens like a couple of times each match (45-50 mins matches)
