Guild Wars 2

I’m sorry I forgot to state but im using a laptop and the W and 2 keys are not working properly, they work but will stop working at the same time for a short period of time and i don’t know what is causing this, I have done an anti virus and anti malware scan but it did not help. I do use the W and 2 keys often and when they are unresponsive it is very hard to play the game :l ( I don’t use overwolf )

I don’t know why, but whenever i play WvW or PvP after a while, it starts to become unresponsive and i die because of this and it is frustating. Can anyone help me fix this problem? Also a side note, this happens even out of PvP and WvW, like in PvE but it does not occur as often.
