A weird problem

[Shady]

everything was working fine
but suddenly my speakers turned mono instead of stereo the right one was only working
i tought may be there is something wrong with the driver (sinceall the wires are ok) then i decided to reinstall windows
and the problem remained

then suddenly it worked fine again stereo

i dont wanna pass this situation i wanna know what really happened

if anyone has any idea what the hell is this ???

Reinstalling windows might have a been a bit drastic solution to begin with, but atleast you got a clean windows now.

Just coz all your wires are plugged in, doesn't mean they can't be bad.
try to move your wires while playing some music and see if the left speaker works perfect. try moving in all directions at all connections to make sure. What kind of speaker system do you have? Are they powered or not?
anyway, it doesn't sound like it is anything inside your pc, rather a wire that has a bad connection.

i dont think u got the idea
the problem is already solved but i want to know the reason
i tried everything u said before i reinstall windows
i even got another speakers and tried them and it worked mono
so my speakers are ok
i reinstalled windows for many other reasons and this is one of them
the problem remained after reinstalling
the problem is suddenly gone with no reason
i just want to know why this could happen
