Hello mmo champion. It apperas i have some problems with my computer and its only effecting my sound.

This is how it is:

Ive been the in the last week been getting static shocks in my hands when picking up my headphones, i have thought its cause i had been petting my cat and gotten static from it. Last night when i picked them up while raiding i got a bad shock and when i put my headphones on i could only hear in the left ear.
the right ear is dead, i tried on 2 diffrent headphones so it must be something with the computer, i checked the audio balance levels in the standard audio control and the one that installed with Motherboard drivers.

Im not really techie so i dont know what the problem could be other than that the audio port got damaged or something? Any help is appreciated.
